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.
