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...

Pupils take photos from a given distance and determine the height of the person using a scale factor. Pupils calculate the ratio of student actual height to student photo height. They take pictures from 3 different distances to see if...

students investigate the concept of using a ratio in the work of construction and solve problems using real life applications. They read descriptions of how various types of construction professionals use ratios on the job. The lesson...

Inventor, astronomer, surveyor, mathematician, clock maker. Learners celebrate the life of Benjamin Banneker by building creative analog clocks, making scale models, and solving problems related to surveying. The activities model the...

Engage scholars in a ratio lesson that employs real-world scenarios. Learners will compare the length and width of pictures and use a table to identify ratio patterns. They watch "Math Can Take You Places" and discuss jobs that use math...

Let's play ball! A great springtime activity to learn about ratios. This activity challenges learners to draw stadiums to scale on standard letter paper and also on construction paper. This three-day lesson includes a pre-assessment...

Sixth graders explore a relevant application of ratios and proportions. They apply this concept through guided practice and interactive feedback.

Students change the scale of a work of art using ratios, percentages, and proportions. While this is technically an art lesson, there is quite a bit of mathematics involved in converting to the correct scale.

Students apply estimation strategies and proportional reasoning to determine a scale comparing the planetary bodies to Earth. They convert measurements of time and distance using scientific notation. Both the metric and customary units...

Students research measurements of the moon and Earth as well as the distance between the two in order to create scale models of the Earth-moon system. With a marble to be used as the moon, they must determine how large to make Earth...

How do scientists determine the best method for removing pollutants from our water sources? Environmental scholars experiment with pollution clean-up options to discover which are the most cost-effective, fastest, and most thorough....

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...

What an impressive task it is to make dental impressions! Pupils learn how dentists use proportional reasoning, unit conversions, and systems of equations to estimate the materials needed to make stone models of dental impressions....

High schoolers review the units of the metric system, and practice estimating measures before actually converting between the two systems of measurement. They participate in activities to visualize a concentration of one part per...

Inspire first grade artists to learn about abstract and realistic art while reading Eric Carle's Where are you Going? To See My Friend. Young artists design and make a mural collage by tearing shapes of paper while comparing English and...

Students identify the elements and principles that appear in an illustration of a room and explain each concept in writing. They watch this movie identifying each of the elements and principles of design portrayed in the interiors of...

In this chemical reaction principles worksheet, students read about definite proportions and the law of conservation of mass. Students read about how to balance a chemical equation. Then students complete 20 fill in the blank, 2 short...

For this geometry worksheet, students use the properties of similar polygons to find the indicated missing length or the scale factor. The two page worksheet contains twenty-two questions. Answers are included.

Students discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl reasoning to...

Eighth graders measure regular baseball bats and souvenir bats in centimeters. They determine how tall a person would be to be in proportion to the souvenir bat, create a poster depicting the person, and explain the proportional...

Now you can create your own monster movie. Learners estimate the size of a scale model monster given comparison statements and analyze these estimates to determine if the scale model accurately portrays a lizard.

A short assessment has individuals determine the scale of a house plan. They use the scale to calculate the size of a door and window that need to be replaced, and then divide a bedroom in two, calculating the size of rooms created.

Explore how resizing an object affects its area. The set of lessons challenges young mathematicians to design a mascot for electronic devices. These designs undergo resizing to determine how scale factors of dilation affect area.
