I made up Lego Geometry to get my nephew excited about area and perimeter. Kids can create big areas by putting legos side by side, or find the area of single bricks. Tell kids not to stress if bricks don't fit perfectly on the grid paper. They can round up. Have them color the area of each of their legos on their grid paper. (Note: For younger kids, you can have them count the lego studs / dots on top to find area and perimeter).

Hi, love this!

ReplyDeleteWe used to use lego in place of quisinaire length rods when my son was younger.

More recently Ive revisited this idea, and added it to my web app GridMaths.com

If you happen to be stuck for gridpaper, this has some nice extras and works on iPad, Chrome, Firefox.

It has some other nice things like counting beans, you can use it do do long multiplication, by putting a digit in each grid square. Its handy when you want to explain multiplication as rectangle area and introduce Distributive Rule etc.

Enjoy, would love your feedback as we make GridMaths more useful.

Hi Erin,

ReplyDeleteDo you also blog here? http://bestactivitiesforkids.com/lego-math/

Just a thought: If you let the younger kids count the dots/studs on the Lego to find the area and perimeter, they are going to incorrectly assume that the area of an object will always be the same as its perimeter. This could cause a lot of confusion down the road.

ReplyDeleteI really like the "Build with Chrome" you recommended, but I can't figure out how to print. Could you point me in the right direction?
