Your teachers have set you a challenge on Sumdog with questions all about subtraction. We would like to find out how much you have remembered about subtraction. It is okay if you don’t know an answer, this means your teacher will know to help you with it. We would like it if you could take your time, read the questions and try your best. The challenge is open for the whole week and doesn’t need to be completed all at once. You might want to wait until after you have done a little bit of numeracy this week as it is all about missing number subtraction. It will be posted on the website on Tuesday.
