EXAMPLE MP1 TASK Dean can remember number facts by rethinking the fact. For example, he remem- bers 7 X 8 by using (7 X 5) + (7 X 3). He recalls 8 X 4 by thinking (8 X 2) + (8 X 2). Use his method to write two ways you could remember 7 X 9. This task depends on students seeing and using mathematical structure. In this case, the number fact is rewritten using a form of the distributive property. This property is the basis for rewriting a different fact in the task challenge
