Formal written method addition year6

This is a complete lesson that I gave to my year 6 class on the formal written method of addition with up to 3 decimal places; it includes differentiated practice questions which can be done on whiteboards (with answers on a separate slide), a (differentiated) worksheet slide which you can print off or get your class to work from the board and choose their own level.

The lesson also includes a slide with the answers to save our valuable teacher time. Why not get your class to self-assess at the end of the lesson?
The lesson is differentiated three ways for lower attaining, middle attaining and higher.
