#TheCompleteSeries5lessons

They will tackle subtraction questions using a variety of different methods. They will also be challenged to use what they know about numbers to help them use partitioning and landmark numbers to solve problems. Over the course of the five lessons in this ‘How can we subtract numbers?’ Complete Series, children use objects, pictures, number lines, hundred squares and mental methods to solve number sentences.
