VIII - Algebra
Standard 8.OA.1.1 - Practice simplifying variable expressions with addition and multiplication.
Included Skills: Number Properties, Algebra, Mixed Equations
Algebraic Expressions • Multiplication and division of algebraic exp. (Coefficient should be integers) • Some common errors (e.g. 2 + x ≠ 2x, 7x + y ≠ 7xy) • Identities ( (a±b)^2 = a^2 ± 2ab ± b^2) Factorisation (simple cases only) as examples the following types: a(x+y), (x±y)^2, (a^2) - (b^2), (x+a)(x+b) • Solving linear equations in one variable in contextual problems involving multiplication and division (word problems) (avoid complex coefficient in the equations)
