# Number Operations

This lesson helps students who are challenged by interpreting language in math ... (more)

This lesson helps students who are challenged by interpreting language in math problems. In the exploration problem the words Ňthree timesÓ becomes a division problem or a missing factor problem. Students with fragile understanding of how multiplication and division are connected are challenged by this language. The intermediary step of drawing a Ňmath pictureÓ or model of the problem, poses a challenge for many students who have limited exposure to models. (4th Grade Math) (less)
