Students identify triangles as similar or congruent. In this geometry activity, students drag triangles around on the navigator to see the effect of different angles on the shape of the triangle. They discuss angle similarity and angle...

Young scholars select appropriate tools and technology to perform tests, collect data, and display data. They construct appropriate graphs from data and develop qualitative statements about the relationships between variables.

Students measure the volume of a clear container using a candle and sand. In this measuring volume lesson plan, students time how long a candle stays lit in a clear glass container. They fill it with sand and find the volume and then use...

Students collect data, use a computer spreadsheet program to create various graphs, and compare the graphs. They state the findings of each graph in writing and decide which graph type best represents the data.

Students construct a bar graph with a given set of data. They calculate the ratio and percent of the data. Students discuss alternate ways of graphing the data as well as multiple strategies to approach the task.

Tenth graders solve for missing sides on a triangle using the Pythagorean Theorem. In this geometry lesson, 10th graders are introduced to basic trigonometry functions as they solve problems of right triangles. They discuss the...

Student are assigned one of the sections on whole numbers. After reviewing the content, they teach their assigned sections to other class mates. They publish their findings on a PowerPoint slide show to use when they teach their section.

Students apply concepts of scales to solve problems. In this geometry activity, students solve real world problems using scales, proportions and ratios. They predict the actual size of a model given the scale drawings.

Sixth graders examine the causes of the stock market crash of 1929.  In this integrated math/history unit on the stock market, 6th graders study, research, and read stocks, visit a local bank, and create a PowerPoint to show the...

In this understanding percent worksheet, students fill in the missing parts for examples of number of colored parts and total numbers and use them to complete charts and rewrite sentences using the exact amount of things and percents....

Students explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...

In this math learning exercise, learners solve three digit addition problems. Some of the addition problems require regrouping. The problems are set up to solve vertically.

In this online percentages worksheet, students access the Library of Virtual Manipulatives web site and open the percentage tool. They use the online tool to complete 8 multi-step questions making graphical representations and finding...

Seventh graders use a protractor to measure angles and solve a problem involving distance. In this measuring angles with a protractor lesson plan, 7th graders calculate the distance of a line on a diagram by using a protractor to measure...

Students explore graphing. In this graphing lesson, students sort Skittles candies and use the color groups to create a bar graph. Rubrics and extension activities are provided.

Students solve problems using geometric means. In this geometry lesson, students create altitudes in right triangles. They use Cabri software to move the triangle around and observe different sides and angles.

Explore rational numbers with the young mathematicians in your class. They will investigate decimals, fractions, and percents before ordering and comparing rational numbers. This multi-day unit includes differentiation activities and...

High schoolers discuss and identify polygons and lines. For this geometry lesson, learners review liner, square and cubic units so they can incorporate it into the lesson on measurement and creating packing that are cost effective.

In this math activity, students will take home a letter to their parents explaining that they are studying Chapter 10: Ratio, Proportion and Percent. Then students will complete a homework activity in which they ask family and friends...

Students explore and experiment with the concept do new kinds of insects appear after soil modification. They assess and review scientific methods of observation, predicting, variables, math skills, ratio, proportions, graphs and the art...

In this math activity, students state the tests for convergence or divergence of a series. Then they apply the tests of convergence and divergence.

Students sort a bag of M&M's by colors and solve a variety of comparison problems. They determine which pile of M&M's has the most, the least, and answer questions comparing two piles. Students also order the piles of M&M's...
