This question tests 4th grade ability to solve multistep word problems with whole numbers using the four operations, including interpreting remainders, representing with equations using variables, and assessing reasonableness with estimation (CCSS.4.OA.3). Multi-step problems require performing two or more operations in the correct order to reach the answer. Students must identify what operations are needed (addition, subtraction, multiplication, or division) based on the problem context, perform them in logical sequence, and ensure each step builds toward the final answer. For problems with division, remainders must be interpreted based on context—sometimes round up (need whole vans), sometimes round down (complete groups only), sometimes the remainder is the answer (how many left over). This problem requires 1 main step with remainder interpretation: divide 157 by 6; the sequence is 157 ÷ 6 = 26 r1. The context requires rounding up because all students must go, so an extra van is needed for the 1 leftover student. Choice B is correct because following the steps: 157 ÷ 6 = 26 r1, rounding up to 27 vans to accommodate all; estimation check: 160 ÷ 6 ≈26.7, rounding up to 27, close to exact 27 vans. Choice A represents using only the quotient without interpreting the remainder, which happens when students don't consider the context for needing to include everyone. To help students: Read carefully and identify ALL steps needed before starting. Determine what to find first, then what to do with that result. Write out steps or use mental notes: Step 1 finds quotient and remainder, Step 2 interprets based on context. For remainder problems, consider context: 'How many vans NEEDED' means round UP (26 r1 → need 27 vans). Use variables to represent unknowns: Let v = number of vans, then v = ceil(157 ÷ 6) = 27. Check reasonableness: estimate by rounding (160 ÷ 6 ≈27), close to exact 27 ✓. Practice breaking complex problems into steps. Watch for: stopping after first step, wrong operation choice, computing in wrong order, misinterpreting remainders, and arithmetic errors.

For problems with division, remainders must be interpreted based on context—sometimes round up (need whole vans), sometimes round down (complete groups only), sometimes the remainder is the answer (how many left over). This problem requires two steps: multiply rows by chairs per row, then add additional chairs. The sequence is: 14 × 8 = 112 initial, then 112 + 17 = 129 total. Choice A is correct because following the steps: Step 1: 14 × 8 = 112, Step 2: 112 + 17 = 129 chairs. Estimation check: 10 × 8 = 80, but 14 × 8 ≈112, +20 ≈132, close to exact 129. Choice B represents only the multiplication without adding, which happens when students don't continue through all steps. To help students: Read carefully and identify ALL steps needed before starting. Determine what to find first, then what to do with that result. Write out steps or use mental notes: Step 1 multiplies to 112, Step 2 adds 17 to find 129. Use variables to represent unknowns: Let c = chairs total, then c = (14 × 8) + 17. Check reasonableness: estimate by rounding (14 × 10 ≈140 +20 ≈160, but adjust for 8 to ≈112 +17=129 ✓). Practice breaking complex problems into steps. Watch for: stopping after first step, wrong operation choice, computing in wrong order, misinterpreting remainders, and arithmetic errors.

This question tests 4th grade ability to solve multistep word problems with whole numbers using the four operations, including interpreting remainders, representing with equations using variables, and assessing reasonableness with estimation (CCSS.4.OA.3). Multi-step problems require performing two or more operations in the correct order to reach the answer. For problems with division, remainders must be interpreted based on context—sometimes round up (need whole vans), sometimes round down (complete groups only), sometimes the remainder is the answer (how many left over). This problem requires 1 step with remainder interpretation: divide total candies by candies per bag. The sequence is: 95 ÷ 7 = 13 remainder 4. The context asks for complete bags AND leftover candies. Choice A is correct because following the steps: Step 1: 95 ÷ 7 = 13 R4, meaning 13 complete bags can be made with 4 candies left over. This matches the context which asks for both complete bags (quotient = 13) and leftover candies (remainder = 4). Verification: 13 bags × 7 candies = 91 candies used, and 95 - 91 = 4 candies left over ✓. Choice C represents an arithmetic error in division, getting the wrong remainder. To help students: For remainder problems, understand what each part means - quotient is complete groups, remainder is what's left. Practice checking division: multiply quotient by divisor and add remainder to verify it equals the dividend (13 × 7 + 4 = 91 + 4 = 95 ✓). Watch for common errors in long division that lead to wrong remainders. Always verify your answer makes sense in the problem context.

Multi-step problems require performing two or more operations in the correct order to reach the answer. Students must identify what operations are needed (addition, subtraction, multiplication, or division) based on the problem context, perform them in logical sequence, and ensure each step builds toward the final answer. This problem requires 3 steps: multiply to find notebook cost, add the pencil case cost, then subtract from payment amount. The sequence is: 4 × $7 = $28, then $28 + $9 = $37, then $50 - $37 = $13. Choice A is correct because following the steps: Step 1: 4 notebooks × $7 = $28, Step 2: $28 + $9 = $37 total cost, Step 3: $50 - $37 = $13 change. Estimation check: rounding gives 4 × $7 ≈ $30, plus $10 ≈ $40 total, $50 - $40 ≈ $10, close to exact answer $13, confirming reasonableness. Choice C represents using only the payment amount without calculating costs, which happens when students don't complete all required steps. To help students: Read carefully and identify ALL steps needed before starting. Determine what to find first (total cost), then what to do with that result (subtract from payment). Write out steps: Step 1 finds notebook cost, Step 2 adds pencil case for total, Step 3 finds change. Use variables: Let c = change, then c = $50 - (4 × $7 + $9). Practice breaking complex problems into steps and always check reasonableness with estimation.

Students must identify what operations are needed (addition, subtraction, multiplication, or division) based on the problem context, perform them in logical sequence, and ensure each step builds toward the final answer. This problem requires 2 steps: multiply to find chairs in rows, then add extra chairs. The sequence is: 9 × 14 = 126, then 126 + 25 = 151. Choice A is correct because following the steps: Step 1: 9 rows × 14 chairs = 126 chairs in rows, Step 2: 126 + 25 = 151 total chairs. The equation is c = (9 × 14) + 25, which gives c = 151. Estimation check: 9 × 14 ≈ 10 × 15 = 150, plus 25 ≈ 175, or more precisely 9 × 14 ≈ 9 × 10 = 90 + 9 × 4 = 126, plus 25 = 151, confirming our exact answer. Choice B represents stopping after the multiplication (126), which happens when students forget to add the extra chairs. To help students: Read carefully for ALL chair sources - both in rows AND near stage. Write the equation: Let c = total chairs, then c = (9 × 14) + 25. Practice identifying when to combine results from different sources. Use parentheses to show order of operations clearly. Check by working backwards: 151 - 25 = 126, and 126 ÷ 9 = 14 ✓.

For problems with division, remainders must be interpreted based on context—sometimes round up (need whole vans), sometimes round down (complete groups only), sometimes the remainder is the answer (how many left over). This problem requires 2 steps: multiply daily pages by days, then add extra on last day. The sequence is: 18 × 7 = 126, then 126 + 6 = 132. Choice B is correct because following the steps: Step 1: 18 × 7 = 126 for 7 days, Step 2: 126 + 6 = 132 total pages. Estimation check: 20 × 7 = 140, plus 6 ≈146, but adjusting for exact 18 gives close to 132, confirming reasonableness. Choice A represents forgetting to add the extra pages, just 18 × 7 = 126, which happens when students don't continue through all steps. To help students: Read carefully and identify ALL steps needed before starting. Determine what to find first, then what to do with that result. Write out steps or use mental notes: Step 1 finds base total, Step 2 adds extra. For remainder problems, consider context: 'How many vans NEEDED' means round UP (26 R1 → need 27 vans). 'How many COMPLETE groups' means quotient only (26 R1 → 26 complete groups). 'How many LEFT OVER' means just remainder (26 R1 → 1 left over). Use variables to represent unknowns: Let n = number of cookies left, then n = (5 × 12) - 8. Check reasonableness: estimate by rounding (5 boxes × 10 cookies ≈ 50, subtract 8 ≈ 42, close to exact 52 ✓). Practice breaking complex problems into steps. Watch for: stopping after first step, wrong operation choice, computing in wrong order, misinterpreting remainders, and arithmetic errors.

This problem requires 2 steps: add 8+16=24 total, divide 24÷4=6. The sequence is: 8+16=24, 24÷4=6. Choice B is correct because following the steps: Step 1: 8+16=24, Step 2: 24÷4=6 pencils each; estimation check: 10+15=25, 25÷4≈6, close to exact 6. Choice A represents wrong order like dividing first then adding wrong, which happens when students perform operations in illogical order. To help students: Read carefully and identify ALL steps needed before starting. Determine what to find first, then what to do with that result. Write out steps or use mental notes: Step 1 finds total pencils, Step 2 divides by friends. Use variables to represent unknowns: Let p = pencils each, then p=(8+16)÷4=6.

For problems with division, remainders must be interpreted based on context—sometimes round up (need whole vans), sometimes round down (complete groups only), sometimes the remainder is the answer (how many left over). This problem requires 2 steps: add collections, then divide by box capacity. The sequence is: 96 + 48 = 144, then 144 ÷ 12 = 12. The context requires the exact quotient since it divides evenly, no remainder interpretation needed. Choice A is correct because following the steps: Step 1: 96 + 48 = 144 total cans, Step 2: 144 ÷ 12 = 12 boxes. Estimation check: 100 + 50 = 150, 150 ÷ 10 = 15, adjusting for exact gives close to 12, confirming reasonableness. Choice B represents possibly dividing one collection only, like 96 ÷ 12 = 8, which happens when students don't add both amounts. To help students: Read carefully and identify ALL steps needed before starting. Determine what to find first, then what to do with that result. Write out steps or use mental notes: Step 1 finds total cans, Step 2 divides by box size. For remainder problems, consider context: 'How many vans NEEDED' means round UP (26 R1 → need 27 vans).

This problem requires two steps: multiply boxes by pencils per box, then subtract given away. The sequence is: 9 × 12 = 108 total, then 108 - 37 = 71 left. Choice A is correct because following the steps: Step 1: 9 × 12 = 108, Step 2: 108 - 37 = 71 pencils. Estimation check: 10 × 12 = 120, -40 ≈ 80, close to exact 71. Choice B represents adding instead of subtracting, like 108 + 37 =145, which happens when students misidentify operation needed. To help students: Read carefully and identify ALL steps needed before starting. Determine what to find first, then what to do with that result. Write out steps or use mental notes: Step 1 multiplies to 108, Step 2 subtracts 37 to find 71. Use variables to represent unknowns: Let p = pencils left, then p = (9 × 12) - 37. Check reasonableness: estimate by rounding (9 × 10 ≈ 90 - 40 ≈ 50, but adjust to 120 - 40 ≈80, close to 71 ✓). Practice breaking complex problems into steps.
