Addition with Regrouping – Year 3 Unit Plan

Teach written addition with regrouping through a clear progression from place-value set-up to confident application. This Year 3 unit helps students understand why regrouping works as they add two- and three-digit numbers, exchange ten ones for one ten, exchange ten tens for one hundred and check that each digit is aligned correctly.

The editable lesson supports explicit teaching and worked examples. Colour displays reinforce the regrouping process, while two hands-on games provide purposeful practice. Five worksheet sets build fluency through calculations, word problems, missing-number challenges and error analysis. Every worksheet page has a matching answer page, and the unit concludes with a two-page assessment, answers and a five-level rubric.
