I made these multicolored base 10 blocks for us to use with our Math U See book. Getting blocks to Germany on the cheap isn’t easy! The colors coordinate with the program as far as the book describes, but I do not have the programs blocks to determine if they are the same size or exact colors.
We printed them off on card stock and laminated them. I am planning on adding magnet strips to the back also so we can “build” our math on the magnet board also!
