Activities in this teaching pack include a differentiated set of worksheets to identify and record how to use addition and subtraction number calculation skills to solve puzzles involving decimals to one place for support ability levels, to two places for core ability levels and to three places for extension ability levels.

The interactive presentation gets the children to explore how to use addition and subtraction number calculation skills to solve puzzles involving decimals to one, two and three places.

This lesson is part of a maths scheme of work to get the children to practise using written calculation methods for decomposition to subtract decimal numbers using different real world contexts and abstract number values. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
