Opens on Chapter 20’s example: the facts grids shaded by strategy: only 15 times facts and 8 addition facts are left once turnarounds and the strategies are counted.
Press New question to start. The grid below shows which facts each strategy covers.
How many facts are left?
From the book, Chapter 20. Of the 100 facts from 0 × 0 to 9 × 9, turnarounds pair most of them up, and the rules for × 0, × 1, × 2, × 5 and × 9 cover many more. What’s left is 15 facts, all from 3, 4, 6, 7 and 8. England’s Year 4 multiplication tables check is 25 on-screen questions, 6 seconds each, with no pass mark.
