Formal written method subtraction year 6 3 lessons

These are 3 whole lessons on Powerpoint that I used to do a lot of revision of the formal written method of with my y6 class last year (they needed the extra practice!). They include lots of opportunities to discuss and model the method, differentiated practice questions (which they can answer on whiteboards) with answers on the next slide so the teacher can quickly check. on each lesson, there is a slide with the Learning Objective and a challenge the children to complete once they have finished independent work. The penultimate slide can be printed off and handed out as a worksheet (subtraction question are differentiated three ways: blue for LAs, orange for MAs and red for HAs). This can also be displayed on the board and the class choose their own level of difficulty. The final slide is the answers which you can use to get the class to mark their own work or the teacher to use -both save time!
