While the lesson focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can they...

RJ and Zoey are at camp and need to get back to the mess hall for lunch, but they don't know how far they have to walk. Help them figure out the distance while teaching young mathematicians how to add and subtract fractions with this...

High school physical scientists collide with motion. They work in pairs to design a paper car that will protect a raw egg during a head-on collision. Measurements of distance traveled, time of run, vehicle specs, and photo gate flags are...

Conversations around the fire, smoke signals, drums. Books, letters, newspapers. Telegraph, radio, television. Telephones, cell phones, the Internet, Twitter, Pinterest. These developments in communication devices, which we take for...

Your young basketball players will build a table and develop a general formula for a decaying exponential scenario involving the rebound distance of a bouncing ball. Using a CBR and graphing calculator can make this even more hands-on...

Your geometry learners use their knowledge of various geometric concepts to write proofs. Starting with givens containing parallel line segments with transversals and triangles and quadrilaterals, and the mid-point and distance formulas;...

Put your students' map skills to the test with this engaging cross-curricular project. Given the task of developing new hiking trails for their local community, young cartographers must map out beginner and intermediate...

The accuracy required by the design and measurement of an Olympic running track will surprise track stars and couch potatoes alike. Given a short introduction, the class then scaffolds into a detailed analysis of the exact nature of the...

Awareness, Avoidance, Distancing. Class members consider the types of protective strategies that would be appropriate in particular situations.

Zoom into the distance with a reading game based on Disney's Cars. Kids use the rules associated with Uno® to match either the character or the word on each card during their turn, or they can skip players, reverse the...

Young musicians are asked to name the eight different intervals pictured on a worksheet that also asks them to identify the low and high notes, the half steps, and the distance between the notes.

Which will make it fly better? Individuals build paper rockets with fins that are launched using straws. After determining an average flight distance, they make adjustments, such as size and location of fins, and try again. A second...

How do you demonstrate radio transmissions? Pupils build a low-energy radio transmitter by constructing two coils from magnet wire and connecting them to audio/phone plugs. The resource provides the details on how to build the...

Add a visual aid to your solar system lessons. Enthusiastic astronomers create a model depicting the nine planets and their distance from the sun. 

Between the time scientists discovered Pluto and reclassified it as a dwarf planet, it did not even make one full revolution around the sun. In two activities, scholars investigate scale models and their properties. Pupils find that it...

How many sides does that polygon have? Building directly from lesson number eight in this series, learners now find the area and perimeter of any polygon on the coordinate plane. They decompose the polygons into triangles and use Green's...

Small groups use the engineering design process to build and test a vehicle capable of carrying 250 grams a distance of five meters. The design must allow for the storage of potential energy and turn it into motion,...

Everyone loves a vacation and a set of three activities has groups planning a tour of the U.K. using given distance, time, and price data. They solve a variety of problems related to the trip and produce a report on the success of...

As of 2015, there are 53,481 oil wells in the Gulf of Mexico. Scholars determine how species diversity is impacted based on the ecosystem's distance from a drilling platform.  It focuses on finding the mean of data sets...

How can a robot measure the length of something when we don't know how far the camera is from the object? The lesson explains the concept of perspective and many others. Scholars apply this knowledge to judge the length of fish and the...

Investigate the complexities of design problems using geometric concepts. The task asks scholars to design a fence for a horse based on the distance it can travel within one hour. It is a seemingly simple task — until individuals learn...

Who knew atoms could be attracted to each other? A simulation allows learners to see how forces between atoms influence the attraction between them. Classes see the attractive and repulsive forces adjusting as distance between atoms...

Show budding mathematicans how to find the sine of pi over 12. The third instructional activity in a series of 16 introduces the addition and subtraction formulas for trigonometric functions. Class members derive the formulas using...

Class members take scale drawings and examine scales to determine distances in the actual objects. Pupils convert the scales of different units to scale factors that can be used in proportional equations.
