Year 7 - Number and Algebra
Standard 7.OA.1.4 - Practice simplifying variable expressions using the distributive property.
Included Skills: Number Properties, Algebra, Mixed Equations
Patterns and algebra • Introduce the concept of variables as a way of representing numbers using letters - understanding that arithmetic laws are powerful ways of describing and simplifying calculations and that using these laws leads to the generality of algebra • Create algebraic expressions and evaluate them by substituting a given value for each variable - using authentic formulas to perform substitutions • Extend and apply the laws and properties of arithmetic to algebraic terms and expressions - identifying order of operations in contextualised problems, preserving the order by inserting brackets in numerical expressions, then recognising how order is preserved by convention - moving fluently between algebraic and word representations as descriptions of the same situation
