create an engaging process with examples and a product differentiated into 3 levels for standard KOA3 Decompose numbers less than or equal to 10 into pairs in more than one way using objects or drawings, and record each decomposition by a drawing or expression.

This learning resource focuses on the concept of decomposing numbers, which involves breaking a larger number into smaller parts. It introduces the Part-Part-Whole model through examples such as breaking the number 5 into pairs (4+1, 3+2, and 5+0). Various activities are provided to practice decomposition for numbers 6, 7, and 8, including drawing circles and filling in equations. The document encourages students to visualize number relationships through counters and balloons, facilitating a hands-on approach to understanding addition and subtraction. In addition, there are independent exercises for decomposing numbers 8 and 9, as well as a challenge to find all ways to decompose 10. The resource culminates with a real-world application and reflection point, allowing students to think critically about number patterns and their practical uses.
