7.1 Verifying addition statements
Verifying Addition Statements
Find out how to decide if an addition statement is true or false by checking that both sides of the equal sign match.
What You'll Learn
Check that the sum on one side of an addition statement equals the value on the other side.
Compute both sides of an equation separately before comparing them, such as \( 6 + 5 \) and \( 4 + 7 \).
Recognize that a statement like \( 8 + 3 = 11 \) is true only when both sides give the same total.
Identify a false addition statement and find the correct sum to fix it.
Apply counting, number lines, or known facts to quickly check each side of a statement.
What You'll Practice
1
Determining whether addition equations are true or false
2
Verifying addition statements with single-digit addends
3
Identifying correct sums up to 20
Why This Matters
Verifying addition statements builds your critical thinking and number sense, essential skills for all math. Being able to quickly spot correct and incorrect equations helps you check your work, catch mistakes, and develop confidence in problem-solving.
