In this article we are going to demonstrate grade eight mathematics (growing patterns) by using computational thinking to support student learning in the 21st century here in Ontario. It is understood you have some knowlege of block coding (eg: Scratch).
To begin, let us take a look at the expectations this task will cover.
- represent linear growing patterns (where the terms are whole numbers) using graphs, algebraic expressions, and equations;
- model linear relationships graphically and algebraically, and solve and verify algebraic
equations, using a variety of strategies, including inspection, guess and check, and using
a “balance” model.
- represent, through investigation with concrete materials, the general term of a linear pattern, using one or more algebraic expressions
- determine a term, given its term number, in a linear pattern that is represented by a graph or an algebraic equation
- make connections between solving equations and determining the term number in a pattern, using the general term
- model linear relationships using tables of values, graphs, and equations
To watch the tutorial, please see below:
As an educator, you cover every expectation listed above but also get an opportunity to make anecdotal notes through conversation about the Learning Skills and Work Habits. Growing Success says you must assess based on conversation, observation and student product. This task provides the perfect opportunity for all three.
As an educator you can extend this task to have students write an app that either a) determines the term value of a specified figure, or b) determines the term number that has said value. Of course, adding the graphing component is always an option.

Can we get high school teachers to do stuff like this?!?!? No offence to high school teachers at all this just seems like a great way of learning!
