EngageNY 60 min(s)Support for English Language Learners
In this lesson, students use Rekenrek bracelets and simple math drawings to show 1 less and 0 less than a number 1-10, and create number sentences to represent each situation. For example, push 1 bead away from a set of 8 beads or cross off 1 picture from a set of 8 pictures, and relate this action to the expression 8 - 1.
