Additive strategies: Video and teaching guide

This video explores the use of computation strategies, rounding and estimation in real-world, additive situations. Use the video with the supporting teacher guide as a springboard to explore mathematical concepts. A range of strategies such as compensation and partitioning are demonstrated. Estimation and rounding are highlighted before mental computation strategies are used to find a precise answer. The teacher guide highlights the key concepts of each video with suggestions on how to follow up in the classroom. The video is one in a series that cover a range of mathematical concepts and are intended to demonstrate maths used in everyday situations.
