Mach Number Problem Set

Keep the planes from crashing. Pupils work with three airplanes and change their flight paths to keep them at a safe distance from each other. Individuals work through three problems in the third interactive in a set of six with...

What do you do to change arrival times of airplanes when a different route is not available? The fifth interactive in a series of six presents problems where pupils must find solutions to conflicts of safety rules. They must decide how...

What is an annulus? Pupils first learn about how to create an annulus, then consider how to find the area of such shapes. They then complete a problem set on arc length and areas of sectors.

Young biochemists examine the reactions that make life possible with this set of practice problems. Focusing specifically on carbohydrate compounds, these multi-step questions challenge students to demonstrate their understanding of the...

This worksheet manages to provide both fun and serious work solving exponential and logarithmic application problems in engaging story lines and real-life situations. A strong emphasis on science applications and numbers pulled straight...

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...

Get three planes to line up safely. Individuals work through a set of problems to eliminate spacing conflicts between three airplanes in flight. The pupils use their knowledge to change the airplanes' speed or route to meet a...

Do pilots create appropriate spacing between aircraft by traveling a longer or shorter path? An interactive presents two airplanes that violate safety protocols. Pupils must determine how to change the path of one plane to create the...

The basics of number theory and set notation are explained in a highly approachable way in a self-contained instructional activity and worksheet. Introducing the vocabulary and concepts from ground zero and building to more complex ideas...

Multiple worked examples and clear explanation of arithmetic steps really make this presentation on conditional probability stand out.  Specifically, an emphasis on the reasoning behind the calculations helps young statisticians develop...
