When I went into a classroom earlier this week a child rushed up to tell me she was 8 that day.

Well, Happy Birthday to everyone who has a birthday today!

This challenge is about finding a variety of ways of asking questions which make a 8.

You might think of 6+2, or 22-14 or…

However, try to create examples that use all the different mathematical ideas that you know about.

Perhaps you could challenge yourself to find ways of making 8 that you think no one else will have thought of.

Here are my answers......

0+8=8

1+7=8

2+6=8

3+5=8

4+4=8

5+3=8

6+2=8

7+1=8

1x8=8

2x4=8

4x2=8

3x6=18-10=8

7x4=28-20=8

6x10=60-50=10-2=8

9x4=36-10=16-8=8

2x10=20-9=11-4=7+1=8

3x9=30-5=25-20=5+3=8

11x4=44-14=30-19=11-3=8

9x8=72-20=52-22=30-11=19-11=8

8x6=48-10=38-14=24-16=8

6x9=54-14=40-20=20-12=8

12x4=48-8=40-25=25-17=8

5x7=35-5=30-30=0+8=8

6x7=42-2=40-10=30-25=5-3=3+5=8

This was actually pretty easy and I thought I went well because I mostly just thought of it in my head and then did it. At first I thought I wasn't going to do any questions at all. But then I thought wrong this was actually fun to do. These bottom questions I just made up I didn't even know what I was adding up to. I think this maths was really enjoyable and really fun as well.
