Part-Whole Models - PowerPoint

Part-whole models are an essential mathematical concept introduced in Year 2, focusing on number and place value. These models help young learners to understand how two-digit numbers can be partitioned into tens and ones. For example, the number 37 can be broken down into 30 (three tens) and 7 (seven ones). This visual representation aids children in grasping the concept of number composition and decomposition, which is foundational for their understanding of addition, subtraction, and number patterns.

The teaching resources include a variety of worksheets and PowerPoint slides that encourage students to complete part-whole models. Through these activities, children practice partitioning two-digit numbers in multiple ways. For instance, the number 36 can be seen as 30 and 6, while 47 can be partitioned into 40 and 7. This approach not only reinforces their understanding of the base-ten number system but also develops their ability to think flexibly about numbers. Additionally, the worksheets are designed to accommodate different representations, such as ten frames, which visually depict numbers and their parts using objects like cars, balloons, sweets, and counters, further enhancing the learning experience.
