These are the perfect task cards to support students to understand the place value system. These cards provide the opportunities for students to rename, add, subtract and regroup. They are designed to be used flexibly with students - a card could be unpacked within a mini lesson or students could work on them independently, in partners or in small groups. The concepts on these task cards will highlight student misconceptions and allow the teacher to identify what stage of learning that student is at. We suggest having concrete materials, such as MAB, accessible to students for support.
