Thank you for visiting! Mirus Toys began as a personal passion ā€” a way to bring wonder-filled, Montessori-inspired materials into homes and classrooms across the country. But as we've grown, so have the challenges. Earlier this year, I reached a difficult crossroads: either find a partner who could carry the mission forward with integrityā€¦ or consider shutting Mirus down. With great care and hope, I chose partnership. Read more about our transition and stock update.


Description

Number manipulation extension to our cloud ten counting board.

Each cloud has 20 raindrops šŸŒ§

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

This material allows the child to add and subtract or which side has more raindropsĀ using greater than/less than symbols in place of the addition and subtraction symbols.

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

This material comes with:Ā 

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

The material is made of maple and finished with linseed oil. The balls are 0.75" round.
