Speeding By The Numbers

Compare two different proportional relationships on a graph. It is up to your mathematicians to determine which of two moving objects have greater speed. A good example of a Common Core multiple choice question. 

Your mathematician's job is to explore the relationship between hours and miles walked during a walk-a-thon. The activity compels your learners to experiment with different means in finding out this proportional relationship. The answer...

Investigate vectors and learn how to use them. Explore why size and direction, as well as knowing speed and distance, are important components of the vector problems you are trying to solve. This is an extensive instructional activity...

Looking for a lesson on vectors?  Here is a PowerPoint that has six examples for finding velocity, acceleration, speed and direction of motion. One of the examples demonstrates the use of the TI-89 Graphing Calculator to solve a problem.

Teaching young mathematicians to use consistent units in their expressions as well as numbers, Sal demonstrates several ways to translate speed units in pre-algebra. He encourages viewers to memorize common speed units, such as the...

Teach the process of multiplying and dividing mixed numbers with a video lesson. The tutorial shows how to multiply and divide these fractions by first converting to improper fractions. After working through two multiplication problems,...

Apply the concept of scientific notation to a word problem involving the rate of speed. Sal explains how to express the answer in scientific notation.

Which numbers are rational and which are irrational? Play an initial speed round with a linked online game to see where kids are at with this concept (you should have already covered it at the basic level). Challenge scholars to consider...

Find the right number of vectors to get to the finish line. Using a boat race scenario, pupils add multiples of the same vector together. The scholars use scalar multiplication to speed up the boats in an exciting race to the finish. 

After viewing an introductory illustrated podcast on speed, distance, time, and velocity, students explore distance-time graphs using interactive websites. Cooperative groups investigate the motion of toy pull-back racers and collect...
