In 2020 I created quite a few algebra videos for the students of Glendowie Primary School. You can locate them on my 2020 Google Site. You might find them helpful. Year 8 includes Algebraic Graphs, which we have been doing also. We are also going to take a little time this week to check out the best way to use Mathletics, and decide if we think it is worth the money.
Note that working with quadratics is Level 5 (Year 10) of the New Zealand Curriculum.
Equations and expressions: Form and solve linear and simple quadratic equations.
In order to solve simple quadratic expressions we need to know how to expand and factorise them. Quadratics are not in Level 4 of the NZC at all, however, this causes issues at secondary school level as students are expected to learn way too much content in too short a space of time. Learning some of the basics now will really help students succeed at secondary school mathematics.
