The original drawing is eight units — how big is the scale drawing? Classmates determine the scale percent between a scale drawing and an object to calculate the length of a portion of the object. They use the percent equation to find...

Design your dream classroom. The lesson plan contains an exercise to have teams create a scale drawing of their dream classroom. Pairs take the measurements of their classroom and furniture and create a scale factor for them. To finish...

Calculate the areas of scale drawings until a more efficient method emerges. Pupils find the relationship between the scale factor of a scale drawing and the scale of the areas. They determine the scale of the areas is the square of the...

Pupils determine scale factors from one figure to another and the scale factor in the reverse direction. Scholars compute the percent changes between three figures. 

Review the principles of scaling areas and draws a comparison to scaling volumes with a third dimensional measurement. The exercises continue with what happens to the volume if the dimensions are not multiplied by the same...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

Can you hear me from there? Pupils determine the place to build a cell tower on a hill. The class uses constraints and creates a scale drawing on a coordinate system to calculate the exact location of the base of the cell tower.

Pack just enough to fit. Crews determine what personal items to take with them on a trip to Mars. Each team must decide what to take with them on a two-and-a-half year trip to Mars and whether their items will fit within the allotted...

Let me break it down for you! Introduce your class to a way of breaking up a complicated task into its component pieces. Individuals draw a complex figure using JavaScript and then break it down to help determine the...

Scholars use interactive resources to figure out how to mathematically draw a reflection of a geometric shape viewed in a mirror. To conclude the activity, class members are asked to deduce the result of multiple reflections across...

Develop a more precise definition of similar. The lesson begins with an informal definition of similar figures and develops the need to be more precise. The class learns about dilations and uses that knowledge to arrive at a...

How are messages to the right recipient? Introduce the concept of routing Internet traffic by drawing a comparison to sending a letter. Groups use the Internet Simulator program to send messages to others using the same router...

It's a balancing act! Pupils balance pennies on a ruler to create a physical representation of a dot plot. The scholars then find the distances of the data points from the balance point, the mean.

Just about every public building that your high schoolers are familiar with has an access ramp which complies with ADA requirements. As it turns out, designing such a ramp is an excellent activity to incorporate slope, the Pythagorean...

Teams use the design process to design, build, and test a model levee to protect the town from a wall of water. A handout provides a price list for the materials learners can use to build their levee within a budget.

Find the percent of the population that meets the criteria. The 17th segment of a 20-part unit presents problems that involve percents of a population. Pupils use tape diagrams to create equations to find the percents of subgroups...

Preparing for an AP test is about more than bubble sheets and memorization. The two activities in this resource require a direct application of skills learned throughout an AP Physics course.

Challenge the class to prove that the dilation properties always hold. The activity develops an informal proof of the properties of dilations through a discussion. Two of the proofs are verified with each class member performing the...

Show your class how to experience their world with the five sense. With worksheets on each sense, learners investigate their surroundings and categorize them into sight, smell, touch, hearing, and taste.
