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.
I know I’m replying to my own post! :-)
This method of teaching math facts has been around for at least 15 years ... I remember teaching it to my kids when I homeschooled them, and they are 20 years old now.
Okay, seems confusing...LOL!
Memorizing multiplication tables is too hard for the little darlings, I guess.
It’s a brave new world.
