Lost Addends

Worksheet Description

The worksheet is filled with a fall theme, designed to help students practice addition facts that make up the number 10. It features a set of equations with one addend provided and the other represented by a box to be filled in by the student, each accompanied by a visual array of fall-themed items, such as leaves and pumpkins, which correspond to the numbers in the equation. The goal for the student is to determine what number needs to be added to the given number to make a sum of 10. The worksheet uses visual aids to support the numerical concepts and includes a “How Did You Do?” section for self-assessment.

This worksheet is teaching the concept of “making 10,” an important foundational skill in arithmetic that aids in understanding the decimal system and facilitates easier mental math. By associating the numbers with visually thematic items, students can engage in learning that is both educational and seasonal. The activity reinforces the concept of number bonds, which are pairs of numbers that combine to form the sum of 10, and helps to develop quick recall of these essential addition facts. Lastly, the worksheet also aims to boost the student’s confidence in math through a self-evaluation process, enhancing their learning experience.
