Wonder Dash and Dot: I have 6 of the Dash robots and we borrowed 3 of the Dots for a few weeks. The students love Dash because he has wheels and can move. Dot, we don't really understand yet. There are free apps by Wonder that can be downloaded to the ipads to code or control the Dashes. The students at first just want to drive them around and race them, but now they have moved on to coding it to make it do anything. We made some mazes using shower curtains from Dollar Tree and tape.
Even the teachers and principal love playing with Dash.
Sphero SPRK: Similar to Dash in that there are apps you can use to drive or code the sphero, but we had to do some troubleshooting for connectivity for these since they run on bluetooth. I have 4 and students would end up controlling someone else's until I labeled each SPRK with their "name" on the bottom with clear tape. The students like racing these and coding them around the mazes as well.
Cubelets: These are sets of different cubes each cube with a different function. When you put the cubes together something happens. We have been using the cards that come with the set to build so far.
Ozobots: Small robots that are coding from colored lines and dashes. Students have been trying to have the ozobots trace their names in cursive and have been designing tracks for them to run on.
All of these have been really fun additions to our makerspace area. I am excited to see what the students will do with them as the year goes on. Now if I could only find a way to keep them all charged.
