#### Measure the Diameter of the Sun

Measuring the diameter of the sun may get a little heated, but using an indirect approach can help individuals keep their cool. Learners use the reflection of the sun to measure how long it takes for it to move one diameter. Using the...

Lesson Planet

#### Modeling Eclipses with Size and Distance Scales

Size within the solar system is a difficult thing for pupils to imagine. Using everyday objects, they build models to show the scale between the sun, moon, and Earth. They situate their props in proportional distances between the objects...

Lesson Planet

#### Scale Ella

Develop a sense of scale. After watching a video about scaling up and scaling down objects, the class participates in a discussion around scale factors. Pupils make a connection between scaling using division and scale factors between...

Lesson Planet

#### Finding Your Place on the Scale (Logarithms)

Linear scales are the standard that most graphs and data use. Converting data to a logarithmic scale can be tricky, but a video presentation thoroughly describes the process. Using visual imagery and specific examples, the lesson...

Lesson Planet

#### Looking at Numbers of Births Using a Line Graph

Was there a baby boom? Using census data, class members take a look at the number of 8-11 year olds and determine their birth years. Scholars create a double line graph to compare the number of births for two states for several years....

Lesson Planet

#### Build-a-Toy

Don't toy with using a fun lesson. Scholars design new toys and then create scale drawings. They determine the volume and surface area of the toys, and then research prices of raw materials to estimate the manufacturing costs.

Lesson Planet

#### How do I Create a Scaled Model of a Full-Sized Basketball Court?

Take mathematics to the hoop! Pairs first measure the linear distances on a basketball court. Using those measurements, they determine the scale lengths to create a scaled model. To finish the activity, learners create models of the...

Lesson Planet

#### The Wheels on the Bus

Find a cheaper way to keep buses going round and round. Small groups use their knowledge of ratios and proportions to find ways to save money on school transportation. The teams determine the number of miles buses currently travel by...

Lesson Planet

#### Area and Volume of Similar Solids: Similar Solids

Five questions make up an interactive designed to boosts knowledge of area and volume of solid figures. Question types include multiple-choice, true or false, and fill-in-the-blank. A scale model changes measurement to provide a visual...

Lesson Planet

#### Solar System Scale

Extremely large or extremely small numbers are difficult to comprehend. To help understand the massive scale of the solar system, learners complete two activities. First, they create a model to compares the size of the bodies in the...

Lesson Planet

#### Grades 7-8 Solving Equations

Create a similar blueprint. The differentiated lesson has pupils work in teams to create a brochure, scale model, or blueprint of a selected house with some minor changes. Once finished, team members present their final projects to the...

Lesson Planet

#### Recipes

Just how much of each ingredient is required? The resource works a few examples of scaling a recipe to feed more or fewer people than outlined. Pupils follow the examples to work out similar problems.

Lesson Planet

#### 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...

Lesson Planet

#### 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...

#### Explore 3D Design

Explore the creativity of your pupils in a design challenge! Learners use a two-dimensional image as inspiration to design a three-dimensional object that has a practical use. Their designs are specific to assigned professions, and they...

Lesson Planet

#### Which Life Form Really Dominates Earth?

Humans only make up 0.01 percent of all life forms on Earth. We sure know how to make an impact though! An episode of the It's Okay to be Smart series examines the proportion of different species that inhabit Earth. The narrator compares...

Lesson Planet

#### Similar Shapes

Similar shapes are all about the scale. Given seven problems, pupils use scale factors to determine measurements within similar shapes. While solving the problem, scholars also determine whether two figures are similar and use area and...
