# What's my Number?

Age Range: 5 - 7
By: Charlotte Hughes

During the Numeracy Hour (for UK schools), there is a big emphasis on getting children to have lots of mental practice. I have devised a good game which the children enjoy playing.

Write the numbers from 1 to 20 up on the board and think of a number.  The children have to guess what your number is by adding two numbers together or taking two numbers away.  The children love it and the the numbers also act as a number line.

Differentiation:

- Children who operate at an lower level can contribute through asking other relevant questions, e.g. is it less than / more than etc.

- For older / more able children, you can make the number line bigger (up to 30, 40 etc.)

This activity is a brillant time filler as well.

I play this game differently but the children are older (secondary). I think of a number between 1-99 and the class get 10 questions which they can ask me to help guess my number. I can only answer yes and no, so questions like "is it odd", "is it prime", "is it more than 50" etc are asked. Most classes enjoy it, but I now make everyone ask a question in turn as it's easy for some children to dominate the activity.

Thanks for this. Trying it tomorrow. Might group the students according to ability after an initial demonstration and get students to take turns thinking of the number.

I did this with my year 4s today. They absolutely loved it. We didn't have a limit on the numbers either, but luckily for me, when they took their turns the numbers they were using were 100 or 1000 and quite round numbers. It still worked really well. Took them a while to get the hang of answering questions that weren't "is it ...?" and guessing a number

basically you have the numbers 1 to 20 on the floor or table and the children will then try to work out the number you are thinking of. For Example: If I was thinking of 15, the children would then use the numbers to guess. 10 + 5 or 20 - 5

Played this today and also changed it for a bit of variety - I got them to write a number on post-it and stick it on my forehead. I then had to ask the questions and work out the answer. This got them really thinking about the questions and the number on my head. The kids absolutely LOVED the game!
