Express natural numbers as products of their factors, recognise multiples...

Quick preparation

• express natural numbers as products of their factors, recognise multiples and determine if one number is divisible by another
• using a certain number of blocks to form different rectangles and using these to list all possible factors for that number; for example, 12 blocks…
• researching divisibility tests and explaining each rule using materials; for example, using base-10 blocks to test if numbers are divisible by 2, 5…
