Description
Understanding what the equal sign really means is one of the biggest steps a first grader takes in math, and this Is It True or False Worksheet makes that idea concrete. Many young students read the equal sign as a signal that says “write the answer here” rather than a statement that both sides hold the same amount. An is it true or false worksheet turns that misunderstanding into a question a child can actually test, because the only way to answer is to add up each side and compare the two totals.
On this printable, students work through eight addition sentences such as 3 + 4 = 4 + 3 and 7 + 6 = 12, add both sides, and fill in the bubble for True or False. Then they finish four number sentences by writing the missing addend that balances the equation. Every sum stays within 20, so the arithmetic is comfortable for 1st Grade and the thinking stays on the equal sign itself. Print the page, hand out pencils, and the whole activity takes about ten minutes.
What’s Included
- One printable page with eight true or false addition sentences
- Fill-in-the-bubble answer choices for True and False
- Four missing addend problems that balance both sides of the equal sign
- A complete answer key on the final page
- Addition facts within 20, written for 1st Grade
Three Reasons This Helps Kids
- It corrects the most common early misconception about the equal sign by asking children to prove that both sides match.
- It builds fact fluency quietly, because each item asks for two sums instead of one.
- It rewards careful reading, since a sentence that looks right can still be false.
Teacher and Parent Ideas
Use this is it true or false worksheet as a warm up before a lesson on balancing equations, or as a quick check after one. Ask students to rewrite each false sentence so that it becomes true, which turns eight items into sixteen. Partners can trade papers and defend one answer out loud, using counters or a number line to show that both sides really are equal. Because this first grade addition worksheet includes an answer key, it also works well at a math center or as homework families can check at home.
