HOW IT HELPS

The Color by Code format keeps practice engaging while still maintaining a clear academic focus.

DIFFERENTIATION
Use the pages in the order that works best for your students. Begin with supported practice during a small-group lesson, and then use the remaining worksheets for independent practice or review.
Students who need additional support may use a hundred chart or place value blocks before progressing to mental math. Students who are ready to work independently can complete the problems without manipulatives or a number chart.
