Comparing the Ratio Method with the Parallel Method
Can you prove it? Lead your class through the development of the Side Splitter Theorem through proofs. Individuals connect the ratio and parallel method of dilation through an exploration of two proofs. After completing the proofs,...

A Scale of the Earth
Students create a scale model of the different eras, periods, and epochs of Earth's 4.6 billion year history. In addition to different time periods, other major events will also be added to the model from fabricated radioactive decay...

Ratio Relationships
Students solve for the different ratio and proportion of a problem. In this geometry lesson, students show their knowledge of how to solve proportional relationships. They convert between percent, decimals and fractions.

Population Problems
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...

Using Ratios to Taste the Rainbow
Students solve problems using ratios and proportion. In this algebra instructional activity, students analyze skittles and their different colors as they apply the properties of ratios and proportions to solve their problems.

Design a Track
Young scholars investigate track and field dimensions, measure an actual track, and construct a scale model. The use of a meter stick, dimensional analysis, and the application of the distributive property to variables forms the main...

Layering the Air
Students study the layer of the atmosphere. In this lesson on the atmosphere, students discuss the composition of the air around us and how the atmosphere was formed. Students create a scale model of the layers of the atmosphere.

Searching a Region in the Plane
Programming a robot is a mathematical task! The activity asks learners to examine the process of programming a robot to vacuum a room. They use a coordinate plane to model the room, write equations to represent movement, determine the...
Curated OER
Graphs
Students graph ordered pairs to model the relationship between numbers. After observing the patterns in ordered pairs, they describe the relationship, and create graphs from a data table. Students describe intervals in the graph, and...
