Students investigate the purpose of map scale and how it is used to measure the distance and the size of objects.

Elementary learners listen to a story, then sort objects from largest to smallest at six different stations around the classroom. Adaptable for a large range of age and ability groups. 

Students meet NASA researchers who describe the relationship between force, energy and motion. They discuss how NASA's experimental X-plane is being tested to make space travel more reliable and show how proportionality and ratios are...

Students figure out the mileage from one state to another using a map. In this map lesson, students look at the scale factor and turn it into a fraction. They measure the distance between two cities and use the proportion to find the...

Learners construct three-dimensional models of the three pyramids at Giza. They research the building of the pyramids and record the height, base and angle measurements of each pyramid. They create a file of facts regarding the pyramids.

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 create their dream house using a spreadsheet for measurements. In this measurements and drawings lesson, students apply concepts of units and conversions as they build and create different shapes. They use Google Sketch-up...

In this chemical reactions worksheet, students review the law of conservation of mass, the principle of definite proportions, and balancing equations. This worksheet has 3 problems to solve.

Young mathematicians work to recognize the relationship between their scale models of the Joides research vessel and the real vessel. They calculate the relationships between various parts of the ship using fractions, ratios, and...

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...

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....

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....

Learners are introduced to the concept of ratios. In groups, they convert sets of numbers into a ratio. After practicing, they use the ratios and proportions to solve story problems. They also calculate map distances and discover map...

Young scholars build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

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.

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.

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 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.

Sixth graders pariticipate in a lesson that focuses on the finding of a ratio and using it to set up a proportion in realtionship to creating a scale drawing. This is done using given problems. It would be valuable for students to have...

Students use centimeter rulers and the attached worksheet containing a scale drawing of a stained glass window. The actual measurements of the stained glass window are given, and students are asked to find the actual measurement of the...

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.

In this similar figures worksheet, students identify the meaning of similar, corresponding sides, and congruent.  They use proportions to find the length of a missing side.  Students dilate given figures according to a scale...

In this nebula worksheet, high schoolers read about the Chandra X-ray Observatory that captured the given image of a pulsar and its nebula. Students solve 3 problems including using similar triangles and proportions to find the image...

Students solve problems of ratio and proportions using hands on. In this algebra lesson, students vary the concentration of a fruit drink using parts of a ratio.
