Math teaching resources by Carole Fullerton
This teacher resource goes beyond mastery of the facts to focus on the manipulation of larger numbers.
Here you'll find lessons for addressing place value and partitioning as precursors to adding and subtracting numbers with sums and differences to and from 1000.
Whole number strategies like compensation, partitioning and using partial sums and differences are taught in a developmental sequence. Games, written practice, real world problems and assessment tasks are included in this 200 page resource.
