The kids played with one at the Cape Cod Children's Museum over the weekend so I told my oldest I would make him one for his birthday party coming up. We're doing some "science-y" things for the party in the backyard. So today I made it - it's 3 feet by 3 feet (pretty darn huge) - and it cost me a whopping $4.22 out of pocket. It will cost you more if you don't already have some of the materials.
How To Make a Geoboard?
(It took me about 2 hours in total and I had to drop $4.22 on paint and nails - already had the wood in my basement)
First, I started with a 3'x3' piece of wood I had in the basement. This was scrap from some project we did way back when and I keep recycling it for birthday party things. I think this is the 4th birthday party it's had use. That's pretty good for a lonely piece of wood.
So I got my wood, the husband's drill, a pencil, and a level/ruler. I marked every two inches on each sides and drew lines down the entire board.
You should have a huge grid. Again, I measured 2".
Then I drilled holes where every line intersected. Since my board was really 35" by 37" (3'X3' is close enough) - I had 17 X 18 holes - or 306 of them. I picked up this can of spray paint for .99 cents at Lowe's.
I spray painted that sucker black.
I was originally going to use screws - but when I went to Lowe's - the cheapest ones they had in the size I needed were about $5.50 for 100. I was NOT going to drop $22 on screws for this project. So I went over to the nails and got a 1 lbs. box of Roofing Nails for $2.98. I didn't have enough - but knew my husband had some in the basement. There were probably about 260 nails in that 1 lbs. box. So I nailed them in to all the holes (all 306 of them - by myself. It was a great way to let out some aggression).
Then I got some rubber bands - and voila! A fun and educational tool for the kids. I'm going to pick up some misc. sizes/colors at Staples with my Staples Rewards for the son's birthday party.
I know it sounds so simple and basic - but this thing can entertain kids like no tomorrow. You don't have to be so extreme in making one - this one is pretty big but my motto is "Go Big or Go Home."
Now you know what the heck a Geoboard is and you know how to make one. Don't you feel all special now? You can buy these too - but they are much smaller and cost a lot more.
