Introduce addition by partitioning and regrouping with these teaching slides, showing students how to break numbers into hundreds, tens and ones before recombining to find the total. Students explore when regrouping is needed, when the partitioned parts add up to 10 or more of that unit, then practise solving addition problems step by step.
What's included:
Introductory slides explaining partitioning and regrouping, including a clear explanation of when regrouping is needed
Modelled examples showing 2 and 3 digit addition solved by partitioning both numbers, with and without regrouping
9 practice slides with problems worked out step by step, with answers revealed one at a time
