من الملائم في هذه مهمة استخدام الطلبة للتكنولوجيا كالآلة الحاسبة البيانية أو حزمة من البرامج الرياضية المجانية، مما يجعل منها أدوات مفيدةً للطلاب للانخراط في معيار رقم 5 في تعليم الرياضيات باستخدام الأدوات المناسبة استراتيجيًا.
This problem includes a percent increase in one part with a percent decrease in the remaining and asks students to find the overall percent change. The problem may be solved using proportions or by reasoning through the computations or writing a set of equations.
This task asks the students to solve a real-world problem involving unit rates (data per unit time) using units that many teens and pre-teens have heard of but may not know the definition for. While the computations involved are not particularly complex, the units will be abstract for many students.
This real world problem is appropriate for mental mathematics and students should be encouraged to think through the solution mentally.
This is a multi-step problem since it requires more than two steps no matter how it is solved. The problem is not scaffolded for the student, but each step is straightforward and should follow from the previous with a careful reading of the problem.
Parts (a) and (b) of the task ask students to find the unit rates that one can compute in this context. Part (b) does not specify whether the units should be laps or km, so answers can be expressed using either one.
