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...

Having a good working knowledge of math vocabulary is so important for learners as they progress through different levels of mathematical learning. Here is 125 pages worth of wonderfully constructed vocabulary and concept review cards....

Third graders investigate ratios and rates.  In this third grade mathematics lesson, 3rd graders identify equal ratios and rate and test for proportionality.  This lesson is created to be use in conjunctions with a particular...

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.

Students explore the relationship between a scale drawing and actual distance. In this mapping instructional activity, students use an amusement park map to determine distances and what they would be like in real life.

Students describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...

Students draw a swan and heron from step-by-step instructions. They discuss characteristics of the swan and its environment. Students study and write a paragraph, story, or report illustrating their picture.

Students discuss the importance of scaling drawings. In this math lesson plan, students create a scaled drawing of circuit boards. They explain why accuracy is very important when scaling.

Students examine folk’s tales for Cause and Effect. In this literature lesson, students read "The Origin of Fire" and "The Origin of Medicine” and look for cause and effect. They use a TI Navigator to write down their findings.

Students use the correct tool to measure distances. For this geometry lesson, students use an odometer and ruler correctly as they study maps. They describe how far way something is.

Scaling needs to be picture perfect. Pupils use proportional reasoning to find the missing dimension of a photo. Class members determine the sizes of paper needed for two configurations of pictures in the short assessment task.

The title says it all: Could King Kong exist? Investigate how increasing the dimensions of an object affects its surface area and volume to mathematically conclude whether a creature with the weight and height of King Kong could actually...

How hard can it be to measure out two pounds? A short performance task introduces a situation where a balance scale is broken. It gives a method for measuring out two pounds and asks learners to evaluate the procedure. They must prove...

Determine whether two triangles are similar. The lesson presents opportunities for pupils to find the criterion needed to show that two triangles are similar. Scholars use the definition of similarity to find any missing side...

Here's a resource teachers won't want to wash their hands of. Given a task where a full bar of soap is on one side of a balance and 3/4 of a bar of soup and a 3/4-ounce weight is on the other side, young mathematicians must determine the...

Host a design challenge of Olympic proportion! Junior engineers build their own bobsleds using simple materials. The activity focuses on kinetic and potential energy and how the center of mass affects motion on a downhill track....

Feel like a detective yet? Pupils first watch a brief clip from the movie The Bone Collector. Using a photo of the suspect's footprint next to a dollar bill, they then use proportions to determine the size of the suspect's shoe.

High schoolers explore Italian Renaissance artwork. In this visual arts lesson plan, students examine "Madonna, Saint Thomas Aquinas, and Saint Paul'" by Bernardo Daddi. High schoolers investigate the use of space, scale, and proportion...

Students utilize mathematical concepts such as: measurement, ratio and proportion and geometric probability to analyze the components of the U.S. Flag. They collect, organize and interpret data by constructing charts, tables and graphs...

Students explore proportional reasoning.  In this middle school mathematics lesson students investigate scale drawings as they create a proportional representation for the carvings on Mt. Rushmore.
