Students learn how to perform addition with decimal numbers using place value and the column method. Number pyramids sums with missing digits are used to challenge the more able. Less able students are encouraged to use a place value table to aid their working.

The start of the lesson recaps ordering decimal numbers. In the main part students are taught how to use the column method by aligning the numbers with the place value table. At the end, students are challenged to solve a real life problem with decimals to assess their progress.
