WTF is a number bond? Hidden partners? WTF is this even saying? And what does this have to do with math?
5 boxes in all, 4 red, 1 blue.
In the top circle in the colored section, goes the 5. In the 2 bottom circles go 1 and 4.
The number bond shown graphically means:
1 + 4 = 5
4 + 1 = 5
5 - 4 = 1
5 - 1 = 4
This is supposed to makes it easier for kids to learn and understand the math facts they memorize at a young age.
When I was a kid, we had to learn the multiplication tables up to 12 x 12. The rest of it, we learned by working arithmetic problems. Not so any more.
