How to explain it
- An equation says two things are equal.
- Use the opposite operation to find the missing number.
- Check by putting your answer back in.
Example: ☐ + 7 = 15. What is ☐? Opposite of adding 7 is subtracting 7. 15 − 7 = 8. Answer: 8
Question 1
What number makes both sides equal?
3 × 5 = + 3
answer box
12
Hint: The = sign means both sides are worth the same. The left side is 3 × 5 = 15. What plus 3 makes 15?
Question 2
What number goes in the box?
295 + = 558
answer box
263
Hint: What do you add to 295 to make 558? Subtract to find it: 558 − 295.
Question 3
Some grapes were shared equally by 7 friends. Each friend got 10 grapes. How many grapes were there?
🍇answer box
70
Hint: Write it as an equation: ☐ ÷ 7 = 10. Multiply to work backwards.
Question 4
Which equation matches the story?
Kenji had 261 stickers.
Kenji gave some away.
Now Kenji has 103 stickers.
- 261 + ☐ = 103
- ☐ − 261 = 103
- 261 − ☐ = 103
- 261 + 103 = ☐
261 − ☐ = 103
Hint: Kenji started with 261. The box is the number given away. Taking it away left 103.
Question 5
Priya had some trading cards and got 40 more. Now Priya has 85. How many cards did Priya have at first?
🃏answer box
45
Hint: Write it as an equation: ☐ + 40 = 85. Subtract to find the box.
Question 6
What is the value of n?
n + 76 = 123
answer box
47
Hint: The letter n stands for an unknown number. Undo the adding: 123 − 76.
Question 7
In which equation does stand for 9?
- ☐ × 5 = 55
- 34 − ☐ = 24
- ☐ + 9 = 16
- 27 ÷ ☐ = 3
27 ÷ ☐ = 3
Hint: Put 9 in the box of each equation and check whether both sides match. It works in 27 ÷ ☐ = 3.
Question 8
Ravi had some trading cards and got 2525 more. Now Ravi has 4185. How many cards did Ravi have at first?
🃏answer box
