Are there any single rods which are equivalent to any of these trains

Make this train:  red, white, red, white, red

Which single rod is equivalent to this train?

What about:

  • red, yellow, white
  • green, red, white
  • red, red, green, green
  • white, pink, green

Make your own trains and find which rod or rods are equivalent to them.

I’ve used the Nrich Cuisenaire Environment to make my picture.  You could do the same if you don’t have any Cuisenaire yet.
