I think its great. I use it for my lower ability y5 children who still need something practical to help their understanding. Great for addition, multiplication, division, subtraction and we also use a letter box that comes with the pack to ask them to post something greater than, less than, equal too etc. Agree with above comment about the amount you need. When I use it I try to borrow other classes so my la table can have a box each. Oh and it is also great for odd and even numbers as they quickly remember which tile has a bit sticking out making it odd.
