Introducing part-whole Year 1 WRM Addition and Subtraction

Hi,
Here is a lesson that can be used to introduce part-part whole model to Year 1 (first lesson of WRM). It uses the structure suggested by the NCETM support for teaching addition and subtraction and breaks down the progress into small steps. The overall lesson could be broken down into small sessions over a couple of days and spread the carousal of activities over the couple of days. The worksheet activities have the STEM sentences at the top.

Hope it is useful :)
