Rounding to the Nearest 10 A hundreds chart is a great way for students to visualize numbers that round to each group of ten. Use one color to highlight numbers that round to another color to highlight numbers that round to and so on.
Spinner with ones and tens. Students get three spins to build the value. Great hands-on tool for teaching place value through billions. Students use a file folder to make a lapbook and then practice working with numbers. Perfect for grades
