Year 5 Pre-Algebra Unit
Click here to preview this resource
Build strong foundations for algebraic thinking with a practical Year 5 unit on missing-number equations and inverse operations. Students connect addition with subtraction and multiplication with division, find unknown values, solve mirror equations and word problems, work through multi-operation challenges, check solutions and explain their strategies.
The resource combines an editable teaching presentation and quiz with a classroom display, eight student worksheet pages, matching answers, two multi-page games, assessment and rubric. The verified unit-plan PDF has 26 A4 pages: one clean Table of Contents page followed by 25 printable resource and answer pages.
