Written Addition and Subtraction - Worked Examples of Exchange

16 different worked examples of being able to exchange across 10s and 100s when using written addition and subtraction.

The examples are set out as following:
Written addition (across 10)
Written addition (across 100)
Written subtraction (across 10)
Written subtraction (across 100)

For each one, there are four different examples. These include two 2-digit examples (one with place value counters and one with Base 10) and two 3-digit examples (again with place value counters and Base 10).

The only exception to this is the written subtraction across 100 where all four examples are 3-digit (2 place value counters and 2 Base 10).

This resource can be used in a number of ways including for display or to be a supportive resource in the classroom to enable children to be independent when completing written addition and subtraction.
