Let children demonstrate all of their maths skills by completing this Year 3 Add 2-Digit and 3-Digit Numbers Mixed Activity. This resource includes three varied fluency questions, one problem-solving question and two reasoning questions for children to apply their knowledge of adding by crossing 10 or 100 to. We've included different representations for some of the questions for added support in this ready-to-use worksheet.

Use this as your independent activity in your class, or use it as a homework task. Alternatively, this can be used in an intervention group for added support or extra challenge where needed. We've included the answers on a separate sheet to save time when marking, or let children use it as a peer or self-assessment tool. The choice is yours!
