This answer key helps fourth grade students and parents check multistep word problems and see every step. Also, each solution names the question for each step, shows the equation, and gives the final answer with a unit.

The key covers all 20 problems, including the estimate in problem 12 and the reasonableness check in problem 20. Then, remainder problems explain why the answer is rounded up, rounded down, or left as the remainder. If your answer differs, find the first step where your work and the key part ways. Also, plan about 15 minutes to check.

Use this answer key to check each multistep problem. Every solution shows the steps in order, with an equation or an estimate where it helps. The final answer, with units, is in bold.

4th grade multi step word problems worksheet answers: worksheet problems 1 to 10

1 – Packs of stickers

Stickers in the packs: $3 \times 8 = 24$.

Total: $s = 15 + 24 = 39$.

$s = 15 + 3 \times 8 = 39$ stickers

2 – Pages read

First 5 days: $5 \times 24 = 120$.

All 6 days: $120 + 18 = 138$.

138 pages

3 – Money left

Four $6 notebooks leave $26.

Cost of notebooks: $4 \times 6 = 24$ dollars.

Money left: $50 – 24 = 26$.

$\$26.00$

4 – Sold bags of apples

Apples in one bag: $36 \div 4 = 9$.

Apples sold: $3 \times 9 = 27$.

27 apples

5 – Card collection

Four bars of 14 make 56.

Ethan: $3 \times 14 = 42$.

Total: $14 + 42 = 56$.

56 cards

6 – Balloons

Balloons in packs: $6 \times 12 = 72$.

Total: $b = 72 + 7 = 79$.

$b = 6 \times 12 + 7 = 79$ balloons

7 – Ticket prices

Adults: $3 \times 12 = 36$. Children: $5 \times 7 = 35$.

Total: $36 + 35 = 71$.

$\$71.00$

8 – Cupcake boxes

Boxes: $144 \div 6 = 24$.

Boxes left: $24 – 9 = 15$.

15 boxes

9 – Canoes

$75 \div 4 = 18 \text{ R } 3$ because $4 \times 18 = 72$.

Three students still need a seat, so round up.

19 canoes

10 – Ribbon bows

$100 \div 8 = 12 \text{ R } 4$ because $8 \times 12 = 96$.

The 4 leftover inches are too short for another piece, so drop the remainder.

12 pieces

Worksheet problems 11 and up

11 – Leftover cards

$53 \div 6 = 8 \text{ R } 5$ because $6 \times 8 = 48$ and $53 – 48 = 5$.

The question asks about the leftover cards, so the remainder is the answer.

5 cards

12 – Estimate and solve

Estimate: $4 \times 20 + 50 = 130$.

Exact: $4 \times 19 = 76$, then $76 + 52 = 128$.

The exact total is close to the estimate, so it is reasonable.

about $\$130.00$; exactly $\$128.00$

13 – Farmers market apples

Three bars of 245 make 735 pounds.

Sunday: $2 \times 245 = 490$.

Both days: $245 + 490 = 735$ pounds.

Bags: $735 \div 5 = 147$.

Check: $147 \times 5 = 735$.

147 bags

14 – School store pencils

Pencils in packs: $8 \times 12 = 96$.

Pencils sold: $3 \times 25 = 75$.

Left: $96 – 75 = 21$.

21 pencils

15 – Team uniforms

Shirts: $8 \times 14 = 112$. Hats: $8 \times 9 = 72$.

Total: $112 + 72 = 184$.

Change: $200 – 184 = 16$.

$\$16.00$

16 – Empty seats

Large sections: $3 \times 1{,}250 = 3{,}750$.

All seats: $3{,}750 + 875 = 4{,}625$.

Empty seats: $4{,}625 – 3{,}980 = 645$.

645 seats

17 – Road trip plan

360 + 4 × 225 = 1,260.

Miles left after day 1: $1{,}260 – 360 = 900$.

Miles each day: $900 \div 4 = 225$.

Check: $4 \times 225 + 360 = 900 + 360 = 1{,}260$.

225 miles

Worksheet problem 18 and after

18 – Cookie bake sale

Bags: $144 \div 8 = 18$.

Money: $18 \times 3 = 54$.

$\$54.00$

19 – Field trip vans

People: $138 + 5 = 143$.

$143 \div 9 = 15 \text{ R } 8$ because $9 \times 15 = 135$.

Eight people still need a seat, so round up.

16 vans

20 – Is it reasonable?

Estimate: about $2{,}450 + 3 \times 130 – 300$, which is about 2,550. Noah’s 7,459 is far too large.

Noah added 128 to 2,450 first and then multiplied by 3. The box books should be multiplied first: $3 \times 128 = 384$.

$2{,}450 + 384 = 2{,}834$ and $2{,}834 – 275 = 2{,}559$.

$2,559$ books

Key facts behind this 4th grade multi step word problems worksheet answers

Key facts

A multistep problem uses two or more of the four operations.
Next, use a letter for the unknown and write an equation, such as b = 6 × 24 − 37.
Solve one step at a time and write units with each answer.
Interpret a remainder by rereading the question: drop it, round up, or use it as the answer.
Check with estimation by rounding the numbers and doing the same steps.

Common mistakes with this 4th grade multi step word problems worksheet answers

Students compare only the last number. Instead, compare each step, because an early slip carries into every later step.
Students skip the unit in the key. Each answer names dollars, pencils, miles, or people, so match your labels.
Students copy the estimate for problem 12 without checking it. Also, round each price yourself and see whether you get the same estimate.
Students ignore the explanation in problem 20. Instead, the key shows how an estimate proves an answer unreasonable.

How to use these solutions

Mark the first step where your work differs from the key. Finally, fixing that step usually fixes the rest.
Redo each missed problem with a bar model. Also, the model shows which operation each step needs. Repeat this habit on every problem for the best results.
Parents can ask the child to explain why a remainder in the van problem makes the answer bigger.

4th grade multi step word problems worksheet answers: frequently asked questions

Why is the answer to problem 19 not 15?

The class has 138 students and 5 teachers, which is 143 people. Dividing by 9 gives 15 with 8 left over. Those 8 people still need seats, so the school needs 16 vans. The remainder forces you to round up.

How does the key solve problem 18?

First divide 144 cookies by 8 to find 18 bags. Then multiply 18 bags by 3 dollars to find 54 dollars. The answer needs both steps, and the unit changes from cookies to bags to dollars.

What if my equation looks different from the key?

Different equations can be correct when they give the same answer. Check that each number matches a step in the story. Then solve your equation and compare the result with the key. A quick check like this takes only a few seconds and prevents most errors.
