Socratic questioning to teach Euclidean geometry? "The Nouns of Geometry," followed by "The Verbs of Geometry," and the misfit, "A Beginner's Story - The Equilateral Triangle" are designed to encourage learners to explore various...

What's in a name? Pupils create a data set based on the number of letters in classmates' names. Each group then uses the data to create a visual representation, such as a histogram, circle graph, or stem-and-leaf plot.

Explore websites, complete research, and use technological tools to create a final multimedia presentation on what makes a community special. Learners of all ages work with a partner to research an interesting aspect of their community,...

Examine the consequences of varying speed.  An engaging set of five problem sets challenges young mathematicians by targeting a different grade level from K-12. In the initial lesson, scholars make conclusions about the time it...

More than 100 cities around the world have shifted from fossil fuels to renewable energy sources. Scholars investigate a city wanting to make this switch, but needs help determining how to make the shift. Groups consider all options,...

Just because one integer is larger than another doesn't mean it will make sense right away. Go beyond note taking and show learners, through the use of algebra tiles and a Four-Pan Algebra Balance, how the numbers relate to one...

Students create a search and rescue party. In this geometry lesson, students simulate a rescue operation using math. They calculate the time, rate and solve word problems related to the real world.

Students create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground safety...

Pupils explore the many applications of mathematics in their environment . They formulate and solve mathematics problems. Students describe geometric elements, shapes and relationships. Pupils use technology such as digital cameras and...

Students work cooperatively in groups to research a topic of their choice. They create a multimedia presentation of the information researched. Throughout the project they generate their own progress journals.

Seventh graders review the steps in writing a math problem. They write story problems stating the situation, the problem to be solved, explaining the process used to solve the problem, and state the answer. Students view a PowerPoint...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

It's probably a good idea to use the unit. Young mathematicians learn about conditional probability using Venn diagrams, tree diagrams, and two-way tables. They also take into consideration independence and the addition rules.

Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a...

First there was pi and now there's e. A discovery-based lesson helps learners find a pattern in compound interest as the compounding period changes. Their investigation results in the discovery of the number e. The lesson is the first in...

Ninth graders identify different sources of renewable and nonrenewable energy. In this math lesson, learners calculate their own carbon footprint based on the carbon dioxide they create daily. They use statistics to analyze data on power...

Patterns, patterns, everywhere! Young scholars examine the multiplication table to identify patterns. Their exploration leads to an understanding of the difference of squares and sum of cubes by the completion of the algebra project.

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson to create 3 dimensional...

Students work in small groups to solve the problems presented. The main project, mapping the classroom, use these discussions to collaborate in creating a tangible demonstration of their understanding.

What is an annulus? Pupils first learn about how to create an annulus, then consider how to find the area of such shapes. They then complete a problem set on arc length and areas of sectors.

Right triangles are so special! Use special right triangles to discover the trigonometric ratios. Pairs construct special right triangles and find the values of the ratios of the sides. In the process, they discover the ratios stay the...

Learners add numbers to ten.  In this addition to ten lesson, students play the Ten frame interactive game to learn about addition and facts to number ten.

Approach the lesson from the right angle. A discussion-based lesson leads helps learners understand angles in terms of rotation. Individuals use manipulatives to explore the properties of angles and learn how to name them. The lesson is...

It's all relatively simple once you get the gist. Young mathematicians learn about sample spaces and simple probability by conducting an activity with dice. To complete the second of six parts in the Statistics and Probability unit, they...
