Welcome to 2B's maths page. Last week the children were working on partitioning numbers using their knowledge of place value. For example 35= 3 tens and 5 units. 

This week we are moving on to solving simple problems using our knowledge of number facts.

Have a go at this example:
I am thinking of a number,
I add 7,
I end up with 15,
What number did I start with?


Need some help?
An easy way of working out the answer is to start with the final number and work backwards. With this example I would start with 15 and subtract 7. I am subtracting because it is the opposite to adding. The answer I get is 8. Now, to check that this is correct, I start with the possible number, 8, then add 7. The answer I get is 15, just like in the problem!


For homework this week you have been asked to write three of your own 'Guess my Number' challenges for your friends to solve next week. Write on the sheet and it hand it in on Friday to the maths set teacher.
