Strip Diagrams to Model Computation

Most students at this point can read a word problem, figure out the operation(s) needed, and solve the problem(s). What might be a little more difficult for them is modeling their operation(s) with a strip diagram. This week we worked through all four operations, and discussed what the strip diagrams for each operation could look like. If a student truly understands what is happening with each operation, he/she should be able to model it.
