In this lesson, students use geoboards to explore the relationships between the area of a square and its side length. They also gain a numeric and geometric understanding of squaring a number and envision what the square root of a number looks like.
6-8
In this lesson, students use geoboards to construct non-traditional, "tilted" squares whose side lengths are irrational numbers. This lesson addresses standards in both Number Sense and Measurement.
6-8
In this lesson, students explore regular and semi-regular tessellations. Students use manipulatives to discover which regular polygons will tessellate and which will not. Students will use geometry and measurement to investigate the three regular and eight semi-regular tessellations.
6-8
In this lesson, students learn how to measure the area of the tire footprint on a car and to find air pressure using a tire gauge. Students then find the weight of the car using their fraction multiplication skills.
6-8
In this activity, students work in groups as contestants on a fictitious game show,
Now and Then.
They use their knowledge of percent computations and percent change to
answer each game show question. As a culminating activity, the students
create their own game show and host it in front of the rest of the
class.

The National Bank of Illuminations has been robbed! Students apply their knowledge of ratios, unit rates, and proportions to sort through the clues and deduce which suspect is the true culprit.
6-8
In this lesson, students determine the time it takes for a roller coaster to reach the bottom of its tallest drop. They use tables and graphs to analyze the falls of different roller coasters. Students conclude the study by creating their own roller coaster and providing an analysis of its fall.
6-8
In this lesson, students look at patterns in calendars to determine the day of the week for a particular date. Students also use division to explain why those patterns occur, and then relate them to modular arithmetic. The final assessment is for students to find the day of their birth.
6-8, 9-12
In this lesson, students use proportions and similar figures to adjust
the size of the New York City Subway Map so that it is drawn to scale.
Students are asked to evaluate whether these changes are necessary
improvements.

We are lucky to live in an age where there is a lot of nutrition information available for the food we eat. The problem is that much of the data is expressed in percents and some of those percents can be misleading. This lesson is designed to enlighten students about how to calculate percent of calories from fat, carbohydrates, and protein. The calculations are made to determine if a person can follow the Zone Diet with only McDonald's food items.
