Horizontal Missing Addends

Worksheet Description

This worksheet contains a set of single-digit addition problems where one of the addends is missing, indicated by a blank square. Each problem has a sum provided, and the student’s task is to determine the missing number that completes the addition equation. The problems are sequentially numbered and arranged in a simple, clean format with ample space for students to write their answers.

The worksheet is designed to teach students the concept of inverse operations within the context of addition. By presenting problems with a missing addend, it encourages students to think critically about the relationship between the numbers in an addition equation. This helps to develop their problem-solving skills and understanding of the fact that addition is a commutative operation. Additionally, it provides practice in working with number bonds, which are essential for building mental arithmetic skills and a deeper understanding of number relationships.
