About this resource
Description
Understanding the equal sign is a big step in second grade math, and this true number sentences worksheet helps students see that an equation is only correct when both sides of the equal sign have the same value. Instead of thinking the equal sign simply means “the answer comes next,” children learn to compare both sides and decide whether a number sentence is true or false. This skill builds a strong foundation for addition, subtraction, and the algebra thinking that comes later.
This printable 2nd grade addition worksheet gives students two kinds of practice. In Part A, they read six number sentences and fill in the bubble to mark each one true or false. In Part B, they write the missing number in the box to make each equation balance. Print it for morning work, a math center, homework, or a quick review, and use the included answer key to check work in seconds.
What’s Included
- 1 print-ready PDF worksheet
- Answer key
- 12 true-or-false and missing-number problems (addition and subtraction within 100)
This true number sentences worksheet helps kids in three ways. First, it strengthens number sense by asking students to add and subtract on both sides of the equal sign. Second, it builds real understanding of equality instead of rote answers, which prevents common mistakes later on. Third, the mix of true/false and fill-in-the-blank problems keeps students thinking flexibly about how numbers fit together.
Teachers and parents can extend the skill in playful ways. Build number sentences with counters or a balance scale so children can see when two sides match. Write a sentence on a whiteboard and have your child give a thumbs up or thumbs down for true or false. Challenge students to fix every false sentence by changing just one number. These quick games make practicing equality feel like a fun puzzle rather than a worksheet.
