In this lesson there are five grade 8 and 9 maths problems for higher ability students. Each of the questions require students to connect multiple high-level topics within a single problem.
The five questions connect the following topics:
Fully worked solutions are provided for every question as well as a student handout
Here is a sample of three questions from the five.

In this question students make a comparison between two crops of beans. To make this comparison they will need to use interpolation to estimate the interquartile range and median from the histogram.
Their comparison should use these values to comment on the spread and measure of central location for each crop.
Students are asked to work out the average density of the composite solid. To do this they begin by working out the individual volumes of the frustum and hemisphere.
Should the students need further prompts I encourage them to present the information within a table as shown below.
By laying out the information in this way the majority of the students were able to go on and calculate the total volume and mass of the composite solid.
