This this task about mixing paint requires students to graph ratios on a coordinate plane. It is a standard language in ratio problem.
This this task about mixing paint requires students to graph ratios on a coordinate plane. It is a standard language in ratio problem.
This is a task where it would be appropriate for students to use technology such as a graphing calculator or GeoGebra, making it a good candidate for students to engage in Standard for Mathematical Practice 5 Use appropriate tools strategically.
This task requires students to solves multistep ratio and percent problem.
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 word problem requires students to compute sales tax.
This real world word problem requires multiple steps.
This task requires graphing time and distance.
In this task students use ratio and rate reasoning to solve the real-world problem of a runners rate and distance.
This real world word problem requires students to figure out the scale ratio and unit rate.
In this task students use ratio and rate reasoning to solve the real-world problem of placing a security camara in a shop.
There are a couple of ways to solve this real world word problem.
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.
This real world word problem about calculating a tip in a restaurant requires multiple steps.
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.
