DIY Bead & String Puzzle

We love a good brain teaser here at Maths Week Scotland, and in today's craft activity you can get hands on with your very own DIY bead & string puzzle. First you'll need to make it, then you'll need to solve it! You can get the kids involved in both parts. Trying to solve the puzzle will encourage logical thinking, as well as nurturing patience and fine motor skills.

Watch our short video, or scroll down for detailed written instructions.

Making the puzzle

You will need:

  • a piece of cardboard, ca. 8cm x 16cm
  • a pair of scissors
  • a piece of string, ca. 40cm long
  • a large bead
