# Algebra Makes Sense

This resource from SMILE contains twenty activities focusing on algebra. The activities address different aspects of algebra and are appropriate for a range of learning styles and abilities. The activities in order of difficulty are:

Mapping jigsaws - laws of arithmetic and inverse operations, express functions in words then symbols

Function codes - express functions in words then symbols, find a function given an input and output

Mapping machines - express functions in words then symbols

Straws and triangles - generate and describe integer and practical sequences, find the nth term for a simple sequence

Think of a number - construct and solve simple linear equations

Matching mappings - substitute into expressions and formulae, express functions in words then symbols

Number problems - understand algebraic conventions, construct and solve linear equations

Complete the mappings - substitute into expressions and formulae, express functions in symbols, represent mappings algebraically

Solve it - multiply out a single bracket, solve linear equations, substitute into formulae

Algebra match - express functions in words then symbols, understand algebraic operations

Algebra game - substitute into expressions and formulae, express functions in symbols

Mapping diagrams - generate sequences, including from term to term and position to term definitions

Random code - construct and solve linear equations, substitute into expressions and formulae.

Algebra problems - construct and solve linear equations, express functions in symbols

Algebra sort - express functions in symbols, understand the difference between equations, identities, formulae and functions

Equivalent expressions - construct and solve linear equations including brackets and negatives, derive and substitute into a formula and change its subject

Whose rule is correct? - construct and solve linear equations including brackets and negatives, generate sequences from term to term or position to term definitions, find the nth term

Algebra trail - use index notation, expand the product of two expressions, substitute into expressions and formulae

Letters for lengths - use index notation, construct and solve linear equations including brackets and negatives, substitute into expressions and formulae

Fibonacci-type sequences - construct and solve linear equations including brackets and negatives, generate sequences, find the nth term, substitute into expressions and formulae
