Margin of Error When Estimating a Population Proportion (part 2)
Error does not mean something went wrong! Learners complete a problem from beginning to end using concepts developed throughout the last five lessons. They begin with a set of data, determine a population proportion, analyze their result...
Balanced Assessment
Who's Left?
If you're not right-handed, are you wrong-handed? Young statisticians calculate the percentage of left-handed people using a given data set in the assessment task. They plot data on a scatter plot and consider how the line of best fit...

Design the Mascot
Explore how resizing an object affects its area. The set of lessons challenges young mathematicians to design a mascot for electronic devices. These designs undergo resizing to determine how scale factors of dilation affect area.
Balanced Assessment
Oil Consumption
An assessment presents a chart displaying oil consumption Pupils use the chart to determine the greatest increase in consumption, and then apply that information to figure out when the consumption may reach 100 million barrels a day.
