Exploring Addition: Formal Addition

  • Lesson 3 of 5

Year 4

KS2

SKU: M4IL80683

Start by challenging children to compare and describe similarities and differences between using partitioning to solve addition calculations and using the formal written method.

The included slides explain in simple terms how to use the formal method and show children how to present their work clearly and neatly.

None of the calculations in this lesson require exchanging between ones and tens or between tens and hundreds; allowing children to focus on the fundamentals of this method (exchanging is addressed in lesson 4).
