Mental Math in Unit I

Students are learning how to employ the power of mental math in Margaret Walsh’s Unit I class. The students are working through number stories and using number charts to add numbers. Walsh talked over story problems and asked students to check their equations. “If you know one of the parts is 5 and you know the total is 8, how do you figure out the other part of the problem?” Walsh asked. The students worked together to understand number families, which helped build their confidence with number sense.
