Scale Factors
Is it bigger, or is it smaller—or maybe it's the same size? Individuals learn to describe enlargements and reductions and quantify the result. Lesson five in the series connects the creation of a dilated image to the result. Pupils...

Spring Scale Engineering
After examining how a spring scale works, teams work together to design their own general measurement device. Reading material provides background information, but there is no part of the procedure in which learners handle an actual...

A Model Solar System
If Earth is modeled by a grapefruit, what planet could be represented by a golf ball? This activity uses everyday and not-so-everyday objects to create a model of the Solar System.

Proportions and Scale: Problem Solving Plan, Proportions
Slide into a lesson on proportions. A slider interactive lets users adjust three of the four values in a proportion and automatically updates the fourth value. Scholars use the interactive to help answer a set of challenge questions on...
Balanced Assessment
Don't Fence Me In
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...

Exploring Scale And Ratio
Students measure the actual size and distance of the solar system using scale and ratio. They watch and discuss a video, create a distance-scale solar system model, and compare the scale sizes of planets to their actual sizes.
Balanced Assessment
Scaling the Stars
Examine ratio and scale through coordinate geometry. Scholars use two diagrams of different scale to calculate perimeter and area. Then, individuals use the perimeters and areas to find ratios.
Beyond Benign
Build-A-Math
We can't build our dream house yet, but we can definitely build a model. Scholars use floor plans to build models of their dream homes. Cardboard is as good as any material for this purpose.

Solving Equations Using Balance Scale, Decomposition, and Graphing
There's more than one way to solve an equation — three, actually. Scholars learn how to solve simple linear equations in one variable using three different methods, which include using balance scales, using decomposition (e.g., turning...

Scale Drawing Lesson Plan
Students calculate actual building measurements from a village map using concepts of ratios and scale in this ten lesson mini-unit. They practice measuring angles, multiplying decimals, estimating height and length, and converting metric...

Scale/Ratio
Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

Moons in Comparison
Just how big is Earth's moon? With a hands-on simulation, scholars use Play-Doh to model the sizes of the planets Earth, Mars, Jupiter, and their moons. They make predictions as a class, work together to make their models, and discuss...
