Grade 1 first graders hunt for errors in written equations on this medium-3 worksheet. Nine fill-in items each state an equation is false and ask for the real sum, like '5 + 2 = 8 is false; the real sum is 7.' A four-pair matching activity connects equations to labels such as 'true' or 'false (real sum 7).' Students build the habit of checking both sides carefully.

Equal Sign & True/False Equations
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 5 + 2 = 8 is false; the real sum is 7 .
2. 4 + 3 = 6 is false; the real sum is 7 .
3. 9 = 5 + 3 is false; the right side really equals 8 .
4. 6 + 4 = 9 is false; the real sum is 10 .
5. 7 = 4 + 2 is false; the right side really equals 6 .
6. 3 + 5 = 9 is false; the real sum is 8 .
7. 8 + 2 = 11 is false; the real sum is 10 .
8. 5 = 1 + 3 is false; the right side really equals 4 .
9. 7 + 2 = 10 is false; the real sum is 9 .
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
5 + 2 = 7
→ true
true
4 + 3 = 9
→ false (real sum 7)
false (real sum 7)
6 + 2 = 8
→ true (sum 8)
false (real sum 8)
3 + 5 = 10
→ false (real sum 8)
true (sum 8)
