We're going to be investigating multiples - have a watch of this BBC Bitesize clip to wrap your head around what a multiple is, in case you've forgotten:
Basically, it's a number in a times table. So 9 is a multiple of 1, 3 and 9. 12 is a multiple of 1, 2, 3, 4, 6 and 12.
Here's the investigation. Imagine you have ten cards, each with a digit on them, 0-9;
Can you use all ten cards to make 5 numbers that are multiples of the three times tables? You can join the digits together to make 2 or 3 digit numbers if you like! But - you can only use each card once!
For example, if I was after multiples of 4 I could put the 3 and 6 together to show 36. Or I could just use 4 or 8 on its own. The only thing to bear in mind is using them all, and only using them once.
Brainbox challenge: Caution, Brainboxes only beyond this point!
Use all the digit cards to make 5 numbers which are multiples of the 7 times table!
