Inky Fingers

Keep the bottles of ink well away from the users…

These things are quite fun. They are little rollers which print out sums when rolled down the page. Each roller is in two halves which can be adjusted so that the sums are different. Great for a little someone who just happens to like doing maths. Search for “Roller Teaching Stamp” if you want some.

Just don’t touch the rollers to check whether or they have ink on. They have.
