Subtraction with Regrouping - Year 3

Subtraction with Regrouping - Year 3 provides a structured week of explicit teaching and varied practice. Students first align place values and decide when regrouping is required, then trade tens and hundreds, solve two- and three-digit calculations, regroup across zero and check differences using addition.

The editable presentation supports whole-class modelling and guided discussion. The printable displays and Build It, Trade It, Solve It activity make the regrouping process visible, while Regrouping Quest adds collaborative game practice. Five two-page worksheet sets move from identifying the first trade to calculations, error analysis, a deterministic puzzle and word problems. A two-page assessment, matching answers and a five-level rubric support review and reporting.
