Year 7 - Number and Algebra

Standard 7.OA.1.4 - Use the fact that the angle sum of triangles is 180º and quadrilaterals is 360º to find the missing interior angle.

Included Skills:

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
