The end of this term has had a focus on Linear Equations and Algebra for Year 8 Maths.
Students have been using their mathematical investigative skills to have Bratz dolls safely but excitingly bungee jump from the monkey bars.

Students outlined the problem and determined key information they needed to investigate. This included how much each rubber band would stretch, the length of the Bratz doll from the tip of her head to the knot of the bungee cord and the total height from the top of the monkey bars to the ground. Students experimented with this and took measurements of up to five rubber bands using tables graphs and diagrams to record their information.

Using their knowledge of a definition of a slope and y-intercept, students created a linear equation for their bungee jumps.

Students then either rearranged the equation or extrapolated their data using Demos Graphing calculator do determine how many rubber bands would get the Bratz doll safely close to the ground to create an exhilarating jump based on their goal jump height.

The bungee jump then brought a lot of laughs and analysis as there were some unfortunate Bratz dolls who did not survive the jump (immediate disqualification) and some groups that came very close to the ground which prompted a video assisted review.
