made to order

Description

Number manipulation extension to our cloud ten counting board.

Each cloud has 20 raindrops 🌧

I have added a lighting in the middle of each set of raindrop for
(1) Subitizing
(2) exploring symmetry

You can add and subtract the raindrops.

Or compare which one has more raindrops and add the larger than/lesser than signs.

Just like the cloud ten frame, the intensity of cloud increases and decreases based on the number. Larger the number, higher the intensity.

Comes with
The math manipulative board
42 blue balls aka "raindrops"
22 Numbers aka "clouds" 1-20, 0 and an extra 10.
5 symbols +,-,<,> and =

Board is made of maple and finished with linseed oil. Balls are 0.75" round.
