Students practise problem solving with time tables using multiplication grids, factors and understanding division as the opposite of multiplication.The start of the lesson reinforces multiplication as a more efficient method of long addition. In the development phase students are challenged to complete a series of more difficult multiplication grids and use division as the opposite of multiplication. The plenary is used to introduce factor pairs and square numbers.More able students are challenged to investigate why certain numbers have an odd number of factors. Less able students have access to a 12 by 12 time table grid.
Differentiated Learning Objectives
- All students should be able to recall and apply times table facts up to and including 12 × 12
- Most students should be able to using division as the opposite of multiplication.
- Some students should be able to calculate all the factors of a number.
