Rounding is a frustrating skill for students to learn, but it doesn’t have to be. As teachers, we have lots of tricks to teach students to round (I used to use the rounding rap), but these aren’t effective because they don’t teach students the mathematical reasoning behind rounding. These 48 task cards can help. Each task card provides a number line for students to use when rounding to the nearest ten. Once students understand why rounding works, you can reintroduce those other tricks (although you may find that your students don’t need them!).
