This engaging Part Part Whole and Partitioning Unit guides students through partitioning numbers to 20. This unit uses many visuals to illustrate the part part whole relationship to students. It also includes numerous hands on experiences to consolidate their knowledge of partitioning and the part part whole strategy. Students learn how to use their part part whole knowledge of number to complete addition and subtraction of collections within 20.
