Grade 3 Addition and Subtraction

Solve each puzzle to help organize the pantry. Show your thinking with numbers, words, or a quick drawing. Check that your answers make sense.

Warm-Up: Build the Supply Count

Use place value to work efficiently.

1.The pantry has 36 cans of soup and receives 27 more. How many cans are there now? You may break apart the tens and ones to help.
2.A delivery brings 48 boxes of cereal in the morning and 35 in the afternoon. Which equation finds the total number of boxes?
  • 48 + 35 = 83
  • 48 - 35 = 13
  • 48 + 30 = 78
3.There are 72 apples in a crate. Volunteers place 28 apples in bags. How many apples are left in the crate? Show a subtraction strategy.

Pantry Puzzles

4.A volunteer sorts 29 cans on one shelf and 46 cans on another. How many cans did the volunteer sort altogether?
5.The pantry starts with 91 bags of rice. After giving some away, 56 bags remain. How many bags were given away? Write an equation and solve.
6.Choose the number that makes the equation true: 38 + □ = 70.
  • 32
  • 42
  • 48
7.True or false? 64 - 27 has the same answer as 64 - 20 - 7. Explain or show how you know.
8.A delivery includes 25 cans of beans, 18 cans of corn, and 34 cans of tomatoes. How many cans are in the delivery? Show how you grouped or added the numbers.
9.A shelf holds 80 cans when full. It currently has 53 cans. How many more cans are needed to fill it? Show a strategy using addition or subtraction.
