Introduce non-standard partitioning and explore how numbers can be split in flexible ways to make addition easier. Students compare standard and non-standard partitioning, then practise partitioning one number and adding each part on to solve addition problems.
The introductory slides model how splitting numbers into flexible parts creates easier intermediate totals, preparing students for independent work on mats and worksheets.
What's included:
Introduction slides showing how numbers can be split in standard and non-standard ways
10 practice slides where students work through step-by-step partitioning to find the sum, with answers revealed one at a time
