About this worksheet

What students practice

  • Students explain that the equal sign means both sides are the same amount.
  • Students decide if addition and subtraction equations within 20 are true or false.
  • Students check equations that have a number sentence on both sides of the equal sign.

How to use

Do the first two questions together and show how to work out each side of the equal sign on its own. Students can use counters to check any equation they are unsure about.

Curriculum

Robot Inspector: Check the Equal Sign

Help a robot decide if both sides of each equation are the same amount.

Equal means the same

Nia built a robot named Bolt. Bolt checks equations. Help Bolt learn what the equal sign means.

1.
What does the equal sign = mean?
  • A. The answer comes next.
  • B. Both sides are the same amount.
  • C. Add the numbers together.
2.
Which equation is true?
  • A. 5 + 2 = 8
  • B. 7 − 1 = 5
  • C. 9 = 6 + 3
3.
Write true or false.
Word bank: true · false

8 = 8 is  .

4.
Write true or false.
Word bank: true · false

5 + 1 = 4 + 3 is  .

Stamp true or false

Find the amount on each side of the equal sign. Are the two sides the same?

5.
Help Bolt sort the equations.
2 + 5 = 710 = 4 + 66 + 1 = 89 − 3 = 68 − 2 = 54 = 9 − 412 = 1215 = 10 + 4
TrueFalse
6.
Bolt stamped all of these TRUE. Circle only the ones that really are true.

6 + 2 = 2 + 65 + 5 = 4 + 63 + 4 = 2 + 68 − 1 = 6 + 110 − 3 = 5 + 1

7.
Which equation is false?
  • A. 13 = 10 + 3
  • B. 7 + 4 = 5 + 6
  • C. 14 − 4 = 9 + 2
  • D. 6 + 6 = 12
8.
Check 9 + 3 = 8 + 4 one side at a time. Then write true or false.

Left side: 9 + 3 =  
Right side: 8 + 4 =  
The equation is  .

9.
Check 15 − 5 = 6 + 3 one side at a time. Then write true or false.

Left side: 15 − 5 =  
Right side: 6 + 3 =  
The equation is  .

Help Bolt think

Bolt makes some mistakes. Help Bolt understand the equal sign.

10.
Bolt says 4 + 4 = 8 + 4 is true because 4 + 4 is 8. What mistake did Bolt make?
  • A. Bolt added 4 + 4 wrong. It is not 8.
  • B. Bolt thought the equal sign means subtract.
  • C. Bolt did not look at the whole right side. 8 + 4 is 12, not 8.
11.
Bolt says 9 = 9 is false because there is no plus sign or minus sign. Is Bolt right? Explain.
12.
Write your own true equation that has a plus sign on both sides of the equal sign. Tell how you know it is true.
