Picture of BLOKL - Cardboard Construction Cubes

This is my third Instructable on the topic of BLOKL which I think really does the math on a math manipulative. A set of building blocks that can be played with freely or used to make math puzzles -

  • Affordable
  • Colorful
  • Adaptable
  • Big

Let's build some big blocks!

Step 1: Here's What You Need

Parts List

1. Three Inch Cube Boxes (gloss finish) - lots of places to get these but I think these are great you get 100 for about $20:
If you want to get something else try it first with the washable crayons. The key to this working well is the gloss finish that makes them colorable, cleanable and "re-tape-able".

2. Hot Glue Gun - maybe you have one already? If not even the little low temperature ones will work for this.

3. Scotch® Wall-Safe Tape - CVS, Target, Amazon. This is great stuff, sticks well and comes of smooth surfaces with out tearing.

4. Crayola Ultra Clean Washable Crayons - there are other washable crayons but Crayola has the most consistent color quality in my humble opinion

Thanks for having a look. Scotch Wall Safe Tape is some pretty amazing stuff and makes this project work. A hundred 3" reusable cubes to decorate and build for about $25.
