KS3 Numeracy Year 7
This unit is part of Around ARE Algebra Through Numeracy Problem Solving and Above ARE Algebra Through Numeracy Problem Solving

Objectives

KS3 Programme of Study Statements
-- Model situations by translating them into algebraic expressions.

-- Use and interpret algebraic notation.

-- Simplify and manipulate algebraic expressions to maintain equivalence by collecting like terms.

-- Use the 4 operations, including formal written methods, applied to integers.

-- Solve problems.

-- Use algebra to generalise the structure of arithmetic, including to formulate mathematical relationships.

Lesson Planning

Algebra
Model situations using algebraic expressions; Simplify algebraic expressions involving adding negative integers

Numeracy and problem solving
Investigation: Stars and Crosses (involving revision of adding five or more two-digit numbers; developing fluency)

Algebra and problem solving
Continuation of investigation: Stars and Crosses (including generalisation, using algebra learnt in B1)
