This worksheet is a mathematical tool designed to evaluate students’ ability to decompose numbers up to 10. It consists of three sections, each dedicated to a different number: 2, 9, and 4. In each section, the students are presented with a large square containing the target number and a series of empty boxes next to an equation, indicating the decomposition process. The students are expected to fill in these boxes with numbers that, when summed, equal the target number.
The worksheet is teaching students how to break down numbers into smaller addends—a key concept in early mathematics called decomposition. It is aimed at developing their ability to think about numbers flexibly and to recognize that there are multiple combinations of numbers that can add up to a given sum. By completing this worksheet, students enhance their addition skills and deepen their understanding of how numbers can be composed and decomposed. This foundational skill sets the stage for more complex mathematical operations such as regrouping in addition and subtraction.
