Fall back and slow down. The fourth lesson in a six-part series on air traffic control leads the class to find the difference in distance traveled based upon the difference in speed. Pupils work through a problem related to walking...

Add a sense of excitement to your math class with this race across the country. Using their knowledge of all things circular, young mathematicians work in pairs answering a series of pi-related word problems as they hop from one city to...

See how a marshmallow can hold up a bridge load. Teams take a closer look at the design of bridge piers. They determine the types of loads that might affect a bridge, and, using that information, they calculate the needed cross-sectional...

A great way to practice with unit rates, the activity gives your mathematicians an opportunity to compare different statements and select which are true. They can practice with "choose all that apply" by setting each statement into its...

It's a great day for a bike ride, but how long will it take? Your learners will have to calculate multiple variables in the problem using scaffolded questioning. Different answer choices are given, but you will need to create the table...

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

Your pupil's pet dog and bird are racing down the city streets. In order to know who is going to win, they better know something about calculating rates, the Pythagorean Theorem, and applying those topics to the map of the city. 

In an open-ended problem, learners calculate costs involved in driving an ice cream van. Is it better to park in one place or drive through different neighborhoods? Learners look at these and other factors and must make reasonable...

Educate your class about blood alcohol levels by combining health with math practice. Class members read a little bit about blood alcohol concentration and then solve some problems related to determining alcohol levels and alcohol...

Tired of your students taking you for granite? Use a unit that offers multiple hands-on weathering and erosion labs and interactive activities. Some of the exciting lessons include planning a tour of Australia, using ice...

You can pick up some valuable pointers and practice how to compute problems involving distance, speed, and time. When you finish working your way through the pages you can take an on-line "Test Bite" and check your understanding.

Based off of the hit television show NUMB3RS, this lesson builds upon the familiar d=rt formula for distance to include elements of acceleration as well. The lesson is framed in the context of traffic flow theory, but makes some very...

Students strengthen their communication skills by first learning the meaning of base units and derived units. Then, working in groups, students measure the time for LEGO MINDSTORMS NXT robots and calculate the robots' average speeds at...

Student groups are provided with a generic car base on which to design a device/enclosure to protect an egg as it rolls down a ramp at increasing slopes. During this activity, student teams design, build and test their prototype...

A challenge that combines skills in problem solving and logical reasoning. See if you can figure out who will win the race by determining the rate of speed of each runner. A one page activity from NCTM Math Challenges for Families...
