Positive and negative numbers become more than marks on paper when students play this variation of the card game, Rummy. Engaged in a game involving both strategy and luck, students build understanding of additive inverses, adding integers, and absolute value.

What's at the end of the rainbow or, in this case, the ruler? In this
lesson, students find a treasure using directions involving bearing
(angles) and range (length). In the process, they measure angles
from 0° to 360°, use map scales, and measure lengths.

In this lesson, students analyze ways for calculating weight loss. Students compare the results and choose the method they consider to be the best and most fair.

In this lesson, students use an interactive applet to investigate the formula for the volume of a rectangular prism. Students will construct two origami boxes and use centimeter cubes to measure and compare the volume of the boxes. Students will also analyze how changing the dimensions of the prism affects its volume.

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.
