Year 7 Algebra: Forming Expressions

A fully resourced, mastery-aligned introductory lesson designed to transition Year 7 students seamlessly from arithmetic to algebraic thinking. Built on explicit instruction and cognitive load theory, this pack eliminates foundational misconceptions—such as confusing x + 2 with 2x, writing coefficients after variables, or misinterpreting 30x as place value—before bad habits form.

Students learn to translate additive, subtractive, and multiplicative worded scenarios into clean algebraic expressions, reverse multiplicative structures to extract unit values (e.g., if x pencils cost 12x, finding the unit cost), and interpret constant differences.
