Mixtures, weighted percentages, and varying speeds make problem solving difficult. The resource give learners a strategy for tackling these types of problems effectively. 

Simply find the slope to find the average rate of change. A short video provides the definition of the average rate of change. Using the definition, pupils calculate the average rate of change to solve problems that cover finding average...

Use proportions to determine the travel distance in a given amount of time. The 10th installment in a series of 33 uses tables and descriptions to determine a person's constant speed. Using the constant speed, pupils write a linear...

Ramp up the average rate of change—instantly. Learners use their knowledge of the formula to find the average rate of change to find the instantaneous rate of change. The presenter shows pupils an interactive that demonstrates finding...

An informative presentation covers motion, metric system, conversions, graphing of coordinates and lines, speed, velocity, and acceleration problems, as well as mean calculations. This is the first lesson in a 26-part series.

A middle school test contains two 40-minute sections covering material through algebra. All questions involve applied problem solving or mathematical analysis.

Revisit the 2012 Summer Olympics by having seventh graders calculate the unit rate sprinting speed of the 100-meter gold medal winner. 

Determine just how far to run before dinner. The short assessment asks pupils to determine the distance a person can jog in the time left before dinner. To answer the question, scholars determine the distance if the person jogs one...

How do you graph a sentence? Scholars do just that as they represent relationships between independent and dependent variables with a graphical representation. Given a sentence, they determine the pertinent relationship and create a...

Patterns are extremely helpful when solving a puzzle. Young scholars attempt to find times a bus will pass each stop. They identify a pattern in the known stop times to identify the solutions.

Plan the way to school. Given a map of a school district, class members portray a transportation consultant hired to develop a bus transportation plan that will pick up the eligible riders and get them to school. The plan must contain...

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

Find the faster rate. The resource tasks the class to compare proportional relationships represented in different ways. Pupils find the slope of the proportional relationships to determine the constant rates. They then analyze the...

This program asks students to determine the average KE of a gas molecule in a sample and then find the rms speed of the particles that make up the sample.

Solve problems where you must find the average velocity or speed by analyzing graphs. Hints and helpful videos are available when needed.

Students must find the time it has been falling and the average speed it has been falling between to stories of a garish tower.

This program asks students to determine the average KE of a gas molecule in a sample and then find the temperature of the particles that make up the sample based on the rms speed of the particles.

Practice calculating average velocity and speed from word problems when an object changes directions.

Practice calculating average velocity and speed from word problems when an object moves in one direction.

This lesson provides the learner with example problems on calculating the average velocity of an object undergoing constant acceleration. It is 1 of 2 in the series titled "Practice w/ Average Velocity & Constant Acceleration."
