In this lesson the children need to first make a judgment of equality or inequality using a concrete place-value model and then translate that understanding to the appropriate symbol system. They must also interpret the inequality symbols in two directions: 57 > 39 means both that 57 is greater than thirty-nine and that thirty-nine is less than fifty-seven. As you plan, consider the variability of learners in your class and make adaptations as necessary.
