Following a 3-Part Format For Problem-Based Lessons from Teaching Student-Centered Mathematics by John Van de Walle. Have students express a given problem as an equation in which a symbol is used to represent an unknown number. Then, have the student solve the equation. Here are some pictures that I took on the number balance at the NRich site: 2 + ? = 5 or 2 + _ = 5 etc. 2 + 3 = 5
