Do you need a resource that has 3-digit numbers and tens addition and subtraction example questions? Look no further than our Year 3 3-Digit Numbers and Tens Modelling PowerPoint. This resource includes a range of varied fluency, reasoning and problem-solving questions to help you teach the skills involved in add and subtracting 3-digit numbers and tens without crossing 100. Each question is followed by a model answer page.

Use this at the start of your lesson to model approaches to answer the questions, or to address any misconceptions. Alternatively, this can be used in an intervention group to offer additional support, or display the questions in class as a challenge activity.
