Introduce non-standard partitioning and explore how numbers can be split in flexible ways to make subtraction easier with these editable slides. Students compare standard and non-standard partitioning, then practise partitioning one number to solve subtraction problems, with each answer revealed one step at a time.
What's included:
Introductory slides explaining what partitioning is and comparing standard and non-standard partitions with modelled examples showing subtraction solved by partitioning one number
10 practice slides where students work through step by step partitioning to find the difference, with answers revealed one at a time
