Rounding to the Nearest 10 and 100 explores rounding on a number line and on a place value chart. Students begin exploring the rules of rounding with a hundreds chart to discover the rules on their own without being told the rules. Next, guided practice sheets with thinking steps are provided. Display the guided practice on your SMART board, as handouts for small groups, or send home for homework with struggling students. Guided practice is followed by independent work where students construct number lines on their own. Rounding Riddles and Sidewalk Chalk Rounding are fun ways to stretch the students' brains or offer differentiation for advanced learners.
