Red and Yellow Numbers

Worksheet Description

This worksheet is a visual and interactive tool for teaching the concept of decomposing numbers. It features rows of circles representing counters in two colors, red and yellow, to illustrate different ways to break down the numbers 5, 6, and 7 into two parts. Each row corresponds to a different number and is accompanied by a number bond diagram where students can record the two parts that make up the whole. The counters are arranged in various configurations to provide visual examples of how each number can be split into two sums.

The worksheet is designed to teach students the foundational concept of decomposing numbers, which is to split a number into two or more addends. By using colored counters, it helps students visualize the part-part-whole relationship of numbers in a concrete way. This method of learning aids in building a strong number sense and understanding that numbers can be made up of smaller numbers. It also prepares students for more advanced mathematical concepts, such as addition and subtraction, by establishing a clear understanding of how numbers can be combined and broken apart.
