Here is an alternative to the Montessori golden bead material that can be used at home. I was inspired to make this for Little-N to practice his golden beads equations, for the past three months he has been totally obsessed with lego and spends a lot of time playing with it. He gives all the piece numerical names, so I took it one step further and we made 10 bars, 100 squares and a 1000 cube [only have enough lego for one 1000 cube].
Here are the ten bars we made.

And here is little-N using the lego golden bead material to do some addition sums. These aren't ideal, but make a good alternative for those who are on a tight budget or to spice up the activity a bit.
