Activities in this teaching pack include a set of differentiated worksheets to practise using written methods for addition to calculate the mass of meals that could be served for a school dinner when working with whole and decimal numbers to one and two places.

The interactive presentation gets the children to explore and record how to add ingredients that have been measured in grams for a school dinner meal.

This lesson is part of a maths scheme of work to get the children to explain and model how to use standard written calculation methods for addition, subtraction, multiplication and division when solving measurement problems for mass. There are teaching activities for shared learning, differentiated worksheets to support independent learning and interactive presentations to introduce concepts and key skills.
