40 page booklet of Sphero Indi puzzles (PDF to download)

This printable PDF will keep your students engaged for hours. There are 40 pages worth of puzzles that I use in my Sphero Indi workshops. Several have a problem with a solution on the back. They are designed to be printed on A4 or US Letter-sized paper and each page can be folded to provide either a solution on the back or an extra mind-bending puzzle! 
I put mine in an A5 sized document wallet but originally I made these to be printed, folded and laminated. 

There are plenty of puzzles with missing tiles where students have too work out the best colour to use...or they can flip the page for a solution, which is often fun just to try and duplicate, with their coloured tiles. 
A few puzzles towards the back of the file are even more intriguing as students make patterns with
1) All the tiles!
2) Tiles that make enless loops
3) Tiles that make Figure 8's a reality!
