We're about to begin our rounding and estimating unit. Our district utilizes the Eureka curriculum. I created the reference sheet and worksheets to help my students practice rounding on the vertical number line. It was a little daunting at first but actually makes more sense than just thinking about the good ole 0 to 4 rounds down and 5 to 9 rounds up. This is a great strategy for visual learners. I would recommend sending home the reference for parents and a support at home.
