**Maths Challenge Part 2**

Find as many ways as you can to represent the numbers:

10

32

55

Which number can you find the most ways to represent?

Think about the factors of the numbers e.g. the factors of the number 10 are 1, 2, 5 and 10 (because 1 x 10 = 10 and 2 x 5 = 10)

Which number can you find the most factors for?

**Maths Challenge!**

Find as many ways as you can to represent the number '7'

You could draw seven fingers being shown on two hands, 7 dots, a number story (e.g. I bought three apples and four oranges how many pieces of fruit did I buy?), you could put it in a place value grid (you will only need the ones column for the number seven though), you could draw seven counters on a ten's frame... However you want to do it!

Then I want you to represent 115. Think about how you could represent this without having to draw 115 dots or 115 fingers. Maybe a calculation? Maybe a place value grid? Maybe with counters which represent 5.

And your final number is 14.

Think about the different ways you can represent these numbers. I will be giving you more numbers to try and represent in as many different ways as you can next week!

Here is my example!
