In this Year 2 Place Value Charts Discussion Problem, children are challenged to find multiple ways of using Base 10 equipment to complete a part-whole model with a total of 99. This is the perfect extension activity to deepen children's problem-solving skills. We recommend completing our discussion problem resources in pairs or small groups. There are multiple possible answers, so it's great for children to share their findings with a peer. There's an added answer page to support marking too.
