Addition and subtraction within 20 - Add by making 10 - Worksheet

The "Add by Making 10" worksheet is an engaging educational resource designed to help children strengthen their addition and subtraction skills within the number range of 20. It primarily focuses on the technique of making 10 to simplify calculations. The worksheet presents a series of activities where children are provided with ten frames, either completed or partially filled, to assist them in visualising the addition process. The first activity requires children to read a given calculation and use a tens frame to make the sum, encouraging them to move counters to reach a total of 10. This hands-on approach helps them to understand the concept and complete corresponding sentences to reinforce their learning.

Subsequent activities vary in complexity, catering to different levels of understanding. Children who are more confident with the concept are given calculations and must use tens frames to determine the necessary moves to make 10. They then draw the counters in the tens frames to visually represent their answers. For those who are ready for an additional challenge, there are options to write the calculations themselves after observing a complete tens frame, and then to create their own calculations. The worksheet culminates in a section where children use a red and a yellow pencil to illustrate the process of making 10 during addition, further solidifying their understanding of the concept. The provided answers aid in the self-assessment of their work, ensuring they can identify and correct any mistakes independently.
