True or False Addition Equations Worksheets

An equation is true when both sides have the same value. Calculate the sum and compare it with the number on the other side.

The equal sign means the same value

In 4 + 3 = 7, the left side has a value of seven and the right side also has a value of seven. The statement is true because both sides match. Read the equal sign as “has the same value as,” rather than as a signal to write an answer.

4 + 3 = 8 is false.

Four counters and three more make seven counters. Seven and eight are different amounts, so the two sides do not have the same value.

Check each side

First find the sum on the left. Then read the number on the right. Compare those two values before choosing True or False. Pointing to each side can help a child keep the displayed number separate from the sum they calculated.

If a child copies the number after the equal sign: cover that number temporarily and find the sum with counters. Uncover it and ask whether it matches. A printed equation can be false even though it looks like a familiar addition fact.

Explain a false statement

For 6 + 2 = 9, say, “Six plus two is eight, and eight is not nine.” The answer is False. You may write the correct sum in the working space to explain, but keep the original equation visible so the child can show what was wrong.

Explain a true statement too

For 5 + 4 = 9, a child might count on four from five or use a known fact. Ask what each side is worth. A correct guess of True is less informative than an explanation that both sides equal nine.

Keep the meaning broader than this sheet

Equality also works when the number is on the left: 7 = 4 + 3 says that both sides have value seven. Discuss this example aloud, while recognizing that the generated questions on this worksheet all use addition on the left and one number on the right.

About these six questions

Each set contains three true and three false original equations in a varying order. Addends range from 2 through 9. Correct sums range from 4 through 18, and the displayed right-hand number can be as large as 19.

In this original bank, every false equation has a right-hand number one greater than the correct sum. These are focused addition checks, not a complete assessment of equality. Subtraction equations and calculations on both sides are not generated here. Explain every decision rather than guessing from the number of true answers already found.
