Description
Deciding whether a number sentence is correct is one of the first big ideas in early math, and this true or false addition and subtraction worksheet gives first graders a clear, friendly way to practice it. Students look at an equation such as 9 + 4 = 15 − 2, work out both sides, and decide whether the two amounts really match. That one habit — checking both sides of the equal sign — is what keeps a child from reading the equal sign as a signal that the answer comes next. Every problem on this true or false addition and subtraction worksheet stays within 20, so the arithmetic stays comfortable while the thinking gets a real workout.
This first grade subtraction worksheet prints as a two page PDF. Page one holds six equations to judge as true or false, plus three make it true problems where children write the number that balances the sentence. Page two is the complete answer key. Print it for morning work, a math center, a homework page, or a quick check after a lesson on the meaning of the equal sign. Children simply fill in a bubble for True or False, so the page is fast to score and easy to reuse as a warm up later in the year.
What’s Included
- Six addition and subtraction equations to mark True or False
- Three missing number problems that balance both sides
- Fill in the bubble answer format for quick scoring
- All numbers within 20, matched to first grade
- A complete answer key on page two
Three Reasons It Helps Kids
First, it teaches the equal sign as a balance point rather than a command to compute, which is the single misunderstanding that trips children up later in algebra. Second, it builds addition and subtraction fluency without feeling like a drill page, because every item asks the child to reason about two expressions instead of grinding out one answer. Third, the missing number problems move a child from checking someone else’s work to repairing it, which is a real step up in thinking and a natural bridge to early algebra.
Ideas for Teachers and Parents
Work the sample together on the board and say the reasoning out loud: nine plus four is thirteen, fifteen minus two is thirteen, so both sides match and the sentence is true. Ask children to prove a false item by naming what each side equals. For an extra round, have partners fix every false equation by changing one number, then trade papers and check. The missing number section works well with counters or a number line for children who still need a concrete model.
