## Stained Glass Window Investigation

Stained Glass window – Enrichment (Type 1) Activity

Students use a graphics calculator app. on their iPads to try and create a digital version of their paper version.

Students record their understanding of the differences between linear and quadratic equations and outline other possible uses of this knowledge in the world.

Linear and Quadratic Equations, Graphing Linear and Quadratic Equations, Finding Solutions for Linear and Quadratic Equations, Slope, Y-Intercept, Coordinate Plane, Ordered Pairs, and Coordinates

3 Weeks.

__Description:__**Stage 1:**On a single sheet of graph paper (broken into four quadrants), students create a stained glass window with curved and straight lines.**Stage 2**: Students analyse the lines and curves/parabolas and write down the linear or quadratic equations on top of the lines.**Stage 3:**Students complete their analysis of the lines. In this analysis, you have to include: The gradient, the x and y intercepts, the equation of the line, how you found the equation of one line.**Stage 4:**Reflection/Evaluation: What did you like/not like about this investigation? Did it help you learn the concepts behind linear equations better? How?**Stage 4:**Students display their work for the Maths/Science and technology expo.**Enrichment – Stage 4**:Students use a graphics calculator app. on their iPads to try and create a digital version of their paper version.

Students record their understanding of the differences between linear and quadratic equations and outline other possible uses of this knowledge in the world.
