Answer Key
#
Answer
Explanation
1
C. 1/4
One slice is 1 of 4 equal parts, so it is 1/4 of the pizza.
2
B. 1/6
A unit fraction has 1 as its numerator, and 1/6 is the only choice with a 1 on top.
3
A. 1/3
The first mark after 0 shows 1 of the 3 equal parts, which is 1/3.
4
D. Third mark after 0
With 4 equal parts, each mark is one more fourth, so the third mark is 3/4.
5
D. 1/2
Both fractions have 1 part, but halves are bigger pieces than eighths, so 1/2 is greater.
6
C. 3/6 < 5/6
The pieces are the same size (sixths), so 3 pieces is less than 5 pieces.
7
D. 1/6
With the same numerator, the bigger the denominator, the smaller each piece, so 1/6 is smallest.
8
A. Maria
Both ate 2 pieces, but thirds are bigger than fifths, so 2/3 is more than 2/5.
9
C. Halfway between 0 and 1
1/2 means one of two equal parts, so it sits right in the middle of 0 and 1.
10
B. >
The pieces are both eighths, and 7 pieces is more than 4 pieces, so 7/8 > 4/8.

10. (Multiple choice) Four friends buy 2 pizzas that cost $12.80 each. They split the total cost equally. How much does each friend pay?
• A. $6.40
• B. $3.20
• C. $12.80
• D. $6.04
Answer Key (Teacher Copy)
1. B. 6.25
• Line up the decimal points and write 2.8 as 2.80 so both numbers have two decimal places.
• 3.45 + 2.80: hundredths 5 + 0 = 5; tenths 4 + 8 = 12, write 2 carry 1; ones 3 + 2 + 1 = 6.
• Answer: 6.25. (Choice A comes from lining up the last digits instead of the decimal points.)
2. 7.85
• Write 12.6 as 12.60.
• 12.60 − 4.75: hundredths 0 − 5 needs regrouping → 10 − 5 = 5; tenths 5 − 7 needs regrouping → 15 − 7 = 8; ones 11 − 4 = 7; tens 0.
• Answer: 7.85. Check: 7.85 + 4.75 = 12.60. ✓
3. B. 5.73
• Write 9 as 9.00.
• 9.00 − 3.27: hundredths 10 − 7 = 3; tenths 9 − 2 = 7 (after regrouping); ones 8 − 3 = 5.
• Answer: 5.73. Check: 5.73 + 3.27 = 9.00. ✓ (Choice C, 6.27, comes from subtracting the smaller digit from the larger in each place.)
4. 4.2
• Multiply as whole numbers: 6 × 7 = 42.
• 0.6 has 1 decimal place, so the product has 1 decimal place.
• Answer: 4.2. Estimate check: about half of 7 is 3.5, so 4.2 is reasonable.
5. A. 3.6
• Multiply as whole numbers: 24 × 15 = 360.
• 2.4 has 1 decimal place and 1.5 has 1 decimal place: 1 + 1 = 2 decimal places.
• 360 → 3.60 = 3.6. Estimate check: 2 × 1.5 = 3, so about 3.6 makes sense.
6. 406
• Multiplying by 100 moves each digit two places to the left (the decimal point moves two places right).
• 4.06 → 40.6 → 406.
• Answer: 406.
7. A. 2.1
• Split it up: 8 ÷ 4 = 2 and 0.4 ÷ 4 = 0.1.
• 2 + 0.1 = 2.1.
• Check: 2.1 × 4 = 8.4. ✓
8. 20
• Make the divisor a whole number: multiply both numbers by 10.
• 6 ÷ 0.3 becomes 60 ÷ 3 = 20.
• Check: 20 × 0.3 = 6. ✓ (Think: how many 3-tenths fit in 6 wholes? 10 fit in 3, so 20 fit in 6.)
9. $3.76
• Step 1, total cost: $3.79 + $2.45 = $6.24.
• Step 2, change: $10.00 − $6.24 = $3.76.
• Answer: $3.76. Check: $6.24 + $3.76 = $10.00. ✓
10. A. $6.40
• Step 1, total cost: 2 × $12.80 = $25.60.
• Step 2, split 4 ways: $25.60 ÷ 4 = $6.40.
• Answer: $6.40. Check: $6.40 × 4 = $25.60. ✓ (Choice B, $3.20, comes from dividing only one pizza by 4.)

k = 2/5; $0.40 per pound; $8.00
10
f = (3/4)d; 7.5 cups
Worked solutions
1. Unit rate = total cost ÷ number of ounces = $3.60 ÷ 12 = $0.30 per ounce.
2. Find the price per juice box for each pack.
• 6-pack: $4.50 ÷ 6 = $0.75 per box
• 8-pack: $5.60 ÷ 8 = $0.70 per box
Since $0.70 < $0.75, the 8-pack is the better buy.
3. Miles per hour = miles ÷ hours = (2/3) ÷ (1/4). Dividing by a fraction means multiplying by its reciprocal: (2/3) × (4/1) = 8/3 = 2 2/3 miles per hour (about 2.67 mph).
4. Amount of change = $25 − $20 = $5. Percent change = change ÷ original = 5 ÷ 20 = 0.25 = 25% increase. Common mistake: dividing by the new price (5 ÷ 25 = 20%).
5. Amount of change = 400 − 340 = 60 students. Percent change = 60 ÷ 400 = 0.15 = 15% decrease.
6. Method 1: Discount = 30% of $80 = 0.30 × 80 = $24. Sale price = $80 − $24 = $56.00. Method 2: If 30% is taken off, you pay 70%: 0.70 × 80 = $56.00.
7. In a proportional relationship, k = y ÷ x for every pair.
• 7 ÷ 2 = 3.5
• 17.5 ÷ 5 = 3.5
• 28 ÷ 8 = 3.5
The constant of proportionality is k = 3.5, so the equation is y = 3.5x.
8. Check y ÷ x for each pair.
• Table A: 4 ÷ 1 = 4, but 7 ÷ 2 = 3.5. The ratios are not equal, so A is not proportional. (Its graph would also not pass through the origin: working backward, x = 0 gives y = 1.)
• Table B: 5 ÷ 2 = 10 ÷ 4 = 15 ÷ 6 = 20 ÷ 8 = 2.5. Every ratio is the same, so Table B is proportional, with k = 2.5.
9.
1. An equation in the form y = kx has constant of proportionality k, so k = 2/5.
2. 2/5 = 0.40, so bananas cost $0.40 per pound. The constant of proportionality is the unit rate.
3. y = (2/5)(20) = 40/5 = $8.00.
10.
1. k = cups of flour ÷ dozens of cookies = 3 ÷ 4 = 3/4. So the equation is f = (3/4)d (or f = 0.75d).
2. f = (3/4)(10) = 30/4 = 7.5 cups of flour. Check: 3 cups for 4 dozen and 7.5 cups for 10 dozen give the same ratio, 3/4 = 7.5/10 = 0.75.

Quiz
Name: ______________________  Date: ____________  Period: ______
Directions: Solve each equation. Show all of your work. If an equation has no solution or infinitely many solutions, write that as your answer and explain how you know. Check your answers by substituting them back into the original equation.
1. −2x + 9 = 23
 
 
2. 5x − 4 = 2x + 14
 
 
3. 2(3x + 1) = 4x + 16
 
 
4. 7 − 3(x − 4) = 2x + 4
 
 
5. 4(x + 2) = 4x + 5
 
 
6. 2(3x − 5) + 4 = 6x − 6
 
 
7. ½(8x − 6) = 5x − 9
 
 
8. Gym A charges a $25 sign-up fee plus $10 per month. Gym B charges a $40 sign-up fee plus $7 per month. Write and solve an equation to find the number of months, m, after which both gyms cost the same total amount. What is that total?
 
 
Answer Key
Answers: 1) x = −7 · 2) x = 6 · 3) x = 7 · 4) x = 3 · 5) no solution · 6) infinitely many solutions · 7) x = 6 · 8) 5 months, $75.
1. −2x + 9 = 23 → x = −7
1. Subtract 9 from both sides: −2x = 14
2. Divide both sides by −2: x = −7
3. Check: −2(−7) + 9 = 14 + 9 = 23 ✓
Common error: dividing by 2 instead of −2 and getting x = 7.
2. 5x − 4 = 2x + 14 → x = 6
1. Subtract 2x from both sides: 3x − 4 = 14
2. Add 4 to both sides: 3x = 18
3. Divide both sides by 3: x = 6
4. Check: 5(6) − 4 = 26 and 2(6) + 14 = 26 ✓
3. 2(3x + 1) = 4x + 16 → x = 7
1. Distribute the 2: 6x + 2 = 4x + 16
2. Subtract 4x from both sides: 2x + 2 = 16
3. Subtract 2 from both sides: 2x = 14
4. Divide both sides by 2: x = 7
5. Check: 2(21 + 1) = 44 and 4(7) + 16 = 44 ✓
4. 7 − 3(x − 4) = 2x + 4 → x = 3
1. Distribute −3 (both terms change): 7 − 3x + 12 = 2x + 4
2. Combine like terms on the left: 19 − 3x = 2x + 4
3. Add 3x to both sides: 19 = 5x + 4
4. Subtract 4 from both sides: 15 = 5x
5. Divide both sides by 5: x = 3
6. Check: 7 − 3(3 − 4) = 7 + 3 = 10 and 2(3) + 4 = 10 ✓
Common error: writing −3x − 12 instead of −3x + 12 (forgetting that −3 × −4 = +12).
5. 4(x + 2) = 4x + 5 → No solution
1. Distribute the 4: 4x + 8 = 4x + 5
2. Subtract 4x from both sides: 8 = 5
3. The variable disappeared and 8 = 5 is false, so no value of x works.
Why: both sides have the same x-term (4x) but different constants, so they can never be equal.
6. 2(3x − 5) + 4 = 6x − 6 → Infinitely many solutions
1. Distribute the 2: 6x − 10 + 4 = 6x − 6
2. Combine like terms on the left: 6x − 6 = 6x − 6
3. Subtract 6x from both sides: −6 = −6
4. The variable disappeared and −6 = −6 is always true, so every value of x works.
Why: after simplifying, both sides are identical expressions.
7. ½(8x − 6) = 5x − 9 → x = 6
1. Distribute ½: 4x − 3 = 5x − 9
2. Subtract 4x from both sides: −3 = x − 9
3. Add 9 to both sides: 6 = x
4. Check: ½(48 − 6) = 21 and 5(6) − 9 = 21 ✓
8. Gym word problem → 5 months, $75
1. Write each total cost: Gym A = 25 + 10m, Gym B = 40 + 7m
2. Set them equal: 25 + 10m = 40 + 7m
3. Subtract 7m from both sides: 25 + 3m = 40
4. Subtract 25 from both sides: 3m = 15
5. Divide both sides by 3: m = 5
6. Find the total: 25 + 10(5) = 75 and 40 + 7(5) = 75 ✓
The gyms cost the same, $75, after 5 months.
Suggested scoring: 2 points per question (1 for correct work, 1 for the correct answer) = 16 points. For #5 and #6, full credit requires the simplified statement (8 = 5 or −6 = −6) and the correct conclusion.

Create a 10-question multiple-choice quiz for 4th graders on energy: forms of energy, energy transfer (heat, light, sound, electric current), and conductors vs. insulators. Include 4 choices per question and an answer key with a short explanation for each.

Claude Opus 5.5

The quiz shows each question's explanation after you answer, and you can flip it to flashcard view. Here's the full answer key in one place:

1. **B, Sound.** Sound is energy. A rock, water and a pencil are objects.
2. **C, Motion energy.** Anything that is moving has motion (kinetic) energy.
3. **A, Stored energy.** A stretched rubber band holds potential energy that turns into motion when you let go.
4. **B, From the cup to your hands.** Heat moves from warmer things to cooler things.
5. **C, In straight lines.** This is why flashlights make beams and why things that block light make shadows.
6. **A, Vibrations.** Sound happens when something vibrates. The vibrations travel to your ears.
7. **B, The bulb does not light up.** Current needs a complete, closed circuit, and a gap breaks it.
8. **D, Copper.** Metals are good conductors, which is why wires are made of copper.
9. **C, Wood.** Wood is an insulator, so heat doesn't move through it easily. The metals would get hot.
10. **B, Insulators keep electricity inside the wire.** Plastic and rubber stop current from escaping and protect people from shocks.

If you want to hand this out on paper, I can turn it into a printable worksheet with the answer key on a separate page.

D
Animal cells have no cell wall or chloroplasts, so this is not part of the cell theory.
Part B (4 points each)
8. Sample full-credit answer: Plant cells have a cell wall and chloroplasts, but animal cells do not. The cell wall is a stiff outer layer that supports and protects the plant cell and helps it keep its shape. Chloroplasts capture energy from sunlight to make food (sugar) through photosynthesis.
• 1 point for each correct structure named (2 total); 1 point for each correct job (2 total).
• Also accept a large central vacuole as one structure if the student explains it stores water and helps the plant stay firm. Animal cells may have small vacuoles, so the key idea is the large central one.
9. Sample full-credit answer: Chloroplasts make food (sugar) using sunlight, but they do not release the energy stored in that food. Mitochondria break down the sugar to release energy the cell can use to grow, repair, and do its work. A plant needs both: chloroplasts to make the food and mitochondria to get energy out of it. Mitochondria also keep working at night when there is no sunlight.
• 2 points: chloroplasts make food / store energy in sugar.
• 2 points: mitochondria release energy from that food for the cell to use.
• Watch for the misconception that "plants get energy from the sun, so they don't need mitochondria."
10. Sample full-credit answer: The three parts of the cell theory are: (1) all living things are made of one or more cells, (2) the cell is the basic unit of structure and function in living things, and (3) all cells come from cells that already exist. For example, when I scrape a cut on my knee, new skin cells form by dividing from the skin cells I already have. This supports the idea that all cells come from other cells.
• 1 point for each correct part of the cell theory (3 total).
• 1 point for a reasonable example tied to one part. Other good examples: a microscope view of an onion skin or cheek cells showing living things are made of cells; a single-celled organism like an amoeba or bacterium as a complete living thing made of one cell.
Total: 26 points (Part A 14 + Part B 12)

Answer Key (teacher copy — remove before printing for students)
Part A
#
Answer
Why
1
A
Your body keeps moving forward when the bus stops: an object in motion stays in motion unless a force acts on it (inertia).
2
B
Velocity is speed plus a direction. Only "40 km/h east" gives both.
3
D
Acceleration is any change in speed or direction. A steady speed in a straight line has neither. Turning (C) counts as accelerating.
4
C
Forces come in equal and opposite pairs: gas pushed down, rocket pushed up.
5
B
By F = m × a, the same force on a smaller mass gives a larger acceleration.
Part B
6. Average speed = 5 m/s
• Formula: s = d ÷ t
• Setup: s = 1,200 m ÷ 240 s
• Answer: s = 5 m/s
7. Time = 2.5 h
• Formula: s = d ÷ t, rearranged to t = d ÷ s
• Setup: t = 200 km ÷ 80 km/h (the km cancel, leaving hours)
• Answer: t = 2.5 h (2 hours 30 minutes)
8. Acceleration = 2 m/s²
• Formula: a = (v_f − v_i) ÷ t
• Setup: a = (8 m/s − 2 m/s) ÷ 3 s = 6 m/s ÷ 3 s
• Answer: a = 2 m/s²
9. (a) Net force = 15 N to the right; (b) acceleration = 3 m/s² to the right
• (a) Forces in opposite directions subtract: 40 N − 25 N = 15 N to the right (the direction of the larger force). Students lose the direction point if it is missing.
• (b) Formula: F = m × a, rearranged to a = F ÷ m
• Setup: a = 15 N ÷ 5 kg = 15 kg·m/s² ÷ 5 kg
• Answer: a = 3 m/s² to the right
10. Net force = 3,000 N
• Formula: F = m × a
• Setup: F = 1,500 kg × 2 m/s² = 3,000 kg·m/s²
• Answer: F = 3,000 N (since 1 N = 1 kg·m/s²)
Common mistakes to watch for: dividing time by distance in #6, multiplying instead of dividing in #7, using 8 m/s alone instead of the change in velocity in #8, and adding the forces (65 N) instead of subtracting in #9.

Dancing Directions: Honeybee Communication
Oct 17, 2026 · @Leon
Passage: Dancing Directions
[1] A honeybee colony can hold tens of thousands of bees, and they all need to work together. Because bees cannot speak, they share information through movement and scent. Their most famous message is a dance.
[2] When a forager bee discovers a good patch of flowers, she returns to the hive and performs a "waggle dance" on the honeycomb. She runs forward in a straight line while shaking her body from side to side, then circles back and repeats the pattern. The direction of her straight run tells other bees which way to fly. If she runs straight up the comb, the flowers are in the same direction as the sun. If she runs at an angle, the food lies at that same angle to the left or right of the sun. The length of the waggle signals distance: the longer she waggles, the farther away the flowers are. For food very close to the hive, bees perform a simpler "round dance" that announces food is nearby without giving exact directions.
[3] The inside of a hive is dark, so the other bees cannot simply watch. Instead, they crowd close to the dancer and sense her movements through touch and vibrations. They also smell the flower scent on her body, which helps them recognize the right flowers when they arrive.
[4] Bees also communicate with pheromones, chemical signals that other bees can detect. When a guard bee senses danger, she releases an alarm pheromone that warns the colony and prepares other bees to defend the hive. Interestingly, this alarm scent smells a bit like bananas.
[5] An Austrian scientist named Karl von Frisch spent decades decoding the waggle dance. In 1973, he shared a Nobel Prize for his work. Thanks to his research, we now know that even tiny insects can share remarkably precise information.
Questions
1. (Main idea) Which sentence best states the central idea of the whole passage?
• A. Honeybees live in very large colonies.
• B. Honeybees use dances and scents to share important information with one another.
• C. Karl von Frisch won a Nobel Prize for studying bees.
• D. Honeybees are able to find flowers in the dark.
2. (Main idea) What is the main idea of paragraph 2?
• A. Forager bees collect nectar from many kinds of flowers.
• B. The round dance is more useful than the waggle dance.
• C. The waggle dance tells other bees the direction and distance to food.
• D. Bees can only find food when the sun is shining.
3. (Vocabulary in context) Read this sentence from paragraph 2: "When a forager bee discovers a good patch of flowers, she returns to the hive and performs a 'waggle dance' on the honeycomb." What does forager most likely mean?
• A. A bee that guards the hive entrance
• B. A bee that searches for food outside the hive
• C. A bee that lays eggs
• D. A bee that builds honeycomb
4. (Vocabulary in context) In paragraph 5, the author says bees can share "remarkably precise information." What does precise mean?
• A. Exact and accurate
• B. Loud and noisy
• C. Secret and hidden
• D. Simple and short
5. (Text evidence) Which sentence from the passage best supports the idea that bees do not need to see a dance to understand it?
• A. "Their most famous message is a dance."
• B. "The direction of her straight run tells other bees which way to fly."
• C. "Instead, they crowd close to the dancer and sense her movements through touch and vibrations."
• D. "Interestingly, this alarm scent smells a bit like bananas."
6. (Author's purpose) What is the author's main purpose for writing this passage?
• A. To persuade readers to start keeping honeybees
• B. To entertain readers with a made-up story about a bee
• C. To inform readers about how honeybees communicate
• D. To compare honeybees with other insects
Answer Key
#
Answer
Where to find it in the passage
1
B
Paragraph 1, sentence 2: "Because bees cannot speak, they share information through movement and scent." Paragraphs 2–4 develop dances and scents in turn.
2
C
Paragraph 2, sentence 3: "The direction of her straight run tells other bees which way to fly." Also sentence 6: "The length of the waggle signals distance..."
3
B
Paragraph 2, sentence 1: the forager "discovers a good patch of flowers" and returns to the hive, showing she is a bee that goes out to find food.
4
A
Paragraph 5, sentence 3. Context in paragraph 2, sentences 3–6: the dance gives an exact direction (angle to the sun) and distance.
5
C
Paragraph 3, sentence 2: "Instead, they crowd close to the dancer and sense her movements through touch and vibrations." It follows sentence 1, which says the hive is dark.
6
C
The whole passage gives facts and explanations. Paragraph 1, sentence 2 sets up the topic: how bees share information.

On accuracy: Maryland's charter went to George Calvert, the first Lord Baltimore, but his son Cecilius (the second Lord Baltimore) actually founded the colony. That's why the question says "the Calvert family." For Georgia, the debtor-relief plan is the standard textbook reason, but in practice very few debtors actually settled there.

I can also turn this into a printable worksheet with a separate answer key page.
