# Afterschooling with Geoboards

I finally broke down an ordered a 7 x 7 geoboard. It was only \$6 and now I’m thinking “Why didn’t I buy one of these sooner?” There are soooooo many cool things you can do with geoboards, that I thought I might create a new Pinterest board, all about them.

## It’s really hard for classroom teachers to use math manipulatives “enough”.

Even when teachers have training in using things like geoboards, they might not have enough materials for all 30 students in their room. Then, even if they do have 30 geoboards, they are under enormous pressure by the state to makes sure kids learn computation skills like adding, subtracting, multiplication and division. Sometimes math manipulatives like geoboards sit on the shelf of a classroom, unused.

## The sad thing is that geoboards can actually make learning easy.

They are kick-butt awesome at teaching geometry, fractions, division, multiplication, and logic. But to be fair to teachers (I was one of them so I know), managing geoboards, little boys and rubber bands, is really hard. The rubber band part especially!

That’s why using geoboards one-0ne-one with your child at home “for fun” is a great Afterschooling idea.

This month I’m going to be looking at some cool things you can do with geoboards at home:

1. Area of squares and rectangles
2. Area of triangles
3. More area of triangles
4. How many rectangles?
5. Square numbers
6. Symmetry
7. Congruence
8. Fractions
9. Area of circles
10. Challenge

P.S. If you have never bought a geoboard before, be warned that there are two different types out there, 7 x 7 and 11 x 11. We happen to own both. But the 7 x 7 frame is what I’ll be using for these activities.

Is there an advantage to the 7×7 over the 11×11? I’m intrigued, but unsure of which one to get (my kids are doing, roughly, 1st and 3rd grade math, if that matters).

Do you already own square inch tiles? If you do, then you’ll want to go with the 7 x 7 because then you can combine the two manipulatives in cool way. The 11 x 11 ends up with really little squares.

It also depends if you are going to use an official geoboard lesson book, or just go free-styling like me. Free-styling will work on either size board. But most “official” geoboard lessons use the 7 x 7.

• Jen says:

Thanks! This would be totally free-styling, just something fun to do after school or on the weekends. It sounds like the 7 x 7 is the way to go.
