Missing addend - sums no more than 20 - Exercise 2

This worksheet focuses on helping first graders master the concept of missing addends in addition problems, with sums no more than twenty. Students will see an equation with one number missing and will work to find which number should be added to complete the equation, such as figuring out what plus seven equals fifteen. This engaging exercise builds foundational math skills and helps children develop their problem-solving abilities. It’s great for independent practice, a small-group activity, or as a review before a quiz. Encourage students to use manipulatives like counters if they need extra support to visualize the problems.
