12 years agoGood but not perfect
I bought this to help my grandson (age 7) better understand number concepts. Bought 2 sets and used a postal scale. It was hard to get the numbers to balance, but he was able to ignore the imprecision. He quickly grasped the ideas of weight as involving numbers, the meaning of "=" (e.g. 7+3=10) and that there are multiple combinations of numbers that add up to the same total. Great learning experience.
