Year 6 Adding and Subtracting Decimals Unit

Teach decimal addition and subtraction through a clear sequence of explicit instruction, place-value alignment, estimation, calculation, checking and applied problem solving.

This Year 6 mathematics unit helps students align decimal points, use placeholder zeros, add and subtract decimals accurately, estimate to predict and check results, total lists of decimal values, and solve money, measurement and multi-step problems. The editable presentation supports whole-class modelling, while colour games, structured practice, complete answers, assessment and a five-level rubric support guided and independent learning.
