Who has more beans?
Ayu and Wei sort beans at the market. Ayu has 12 beans and Wei has 7 beans. Ayu says she has more. Wei asks, how many more does she have? Counting every bean is slow and easy to get wrong. A picture of two bars might show the answer fast. By the end I can draw two bars and find how many more one has.
