Full assessment:

• general aim with guiding questions
• background data for authentic context
• criterion D rubric for MYP2/3
• strand-aligned task-specific clarifications
• solutions
• additional marking guidelines

In this task, students are given data for when records were broken by men and women running one mile. They create linear models based on two points at a time and use this to calculate when men will reach a 3.5 minute mile and women a 4 minute mile. They are then directed to reflect on the models and their answers through prompts. This can be completed by hand (on a separate paper) or on the computer. A calculator will be needed.

Students should be able to:

• calculate the gradient of a line
• identify the y-intercept
• find the equation of a line given two points
• solve linear equations
• substitute
• interpret points on a scatter graph

While this was made for MYP2/3 (grades 7/8, years 8/9), it can be used with other year groups by adapting the task-specific clarifications (e.g. MYP4/5 should have a more in-depth reflection to critique the models).

This can be completed in a 50 minute (or longer) lesson, but more time would be beneficial for thorough reflections. If more time can be given, this would work well to be assessed with criterion C (communication) as well.
