After all the design challenges that I competed I had to come up with my own.  We had to pick one of the four platform tools we had been using so far (Pixton, Scratch, Tinkercad  or Soundtrap). Since I am planning to teach middle school math, I made my challenge on volumes. For this design challenge you will need a Tinkercad account and some previous knowledge on volumes. If you would like to participate in my challenge, I have left all my resources bellow.
