Students explore the difference between drawing and constructing a triangle utilizing The Geometer's Sketchpad on the computer. They create, develop and script constructions for both isosceles and equilateral triangles. Each student has...

Young scholars investigate circles and compound locus. In this geometry lesson, students identify the distance from a point to a line. They use Cabri software to create lines and circles.

Students perform translations and reflections. In this algebra lesson, students use the TI calculator to graph functions. They move the functions around on the coordinate plane using translation and reflection.

Students explore different size circles to discover the relationship between diameter and circumference. In this circles and Pi lesson, students construct simple parachutes using circle patterns of varying sizes. Students predict the...

Students examine and calculate the percentage of potable water remaining on the earth. In this ecology and geography lesson plan, students brainstorm the main factors affecting water distribution. Students use mathematical problem...

Students explore the concept of topographical maps.  In this topographical map lesson, students discuss how airplanes know where to fly.  Students use topographical maps to simulate a field trip on the computer. 

Students triangulate using a compass, topographical (topo) map and a view of outside landmarks. They take a field trip to another location away from school and mark discernible landmarks (like mountains or radio towers) and changes in...

Students explore the idea of having Benchmarks to estimate the length of given objects. Students demonstrate acquired knowledge of the basic units of length by making reasonable estimates. Students create a personal benchmark.

Middle schoolers compute area.  In this perimeter, area and volume lesson, students examine given objects and determine the perimeter, area, and volume of each. 

Students demonstrate problem solving skills. Students complete word problems requiring unit conversions. They convert both metric and standard units. Students must determine necessary information to solve problems.

Students determine length, width, perimeter, and surface area, and work with two-dimensional representations of three-dimension objects to design and write descriptions of their dream bedrooms.

Pupils will analyze scales as related to models and real life in this geometry lesson. They work together to compare the dimensions on a model as compared to the real building.

Students calculate the weight of a motor vehicle using only a sheet of graph paper and a tire gauge. Extensions provided offer additional challenges.

Students explore the concept of making ice cream. In this ice cream lesson, students convert an ice cream recipe from metric units to English units. Students then make ice cream from the recipe they converted.

Students explore the parts of an orange to develop an understanding of the addition and subtraction of fractions. The concept of representing parts of a whole by dividing an object into smaller pieces is experienced in this hands-on...

Seventh graders examine the uses of mean, median, and mode. They define key vocabulary terms, observe the teacher model examples of mean, median, and mode, and discuss real world examples of central tendency of sets of data. Students...

Students make sensible estimates and check the reasonableness of the answers. Students write and solve problems involving decimal multiplication and division. Students perform calculations with time.

Learners explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Students estimate the thickness of coins. In this stack up lesson, students stack pennies, nickels, dimes and quarters. They calculate and record the thickness of each coin. Students stack coins and estimate the height of the stack.

Learners collect statistical data.  In groups, students play a dart game and then determine the distance between darts.  They collect the data and plot the information on a coordinate plane.  They identify the mean and the...

Students explore mathematical operations while studying nutrition. In this physical fitness lesson plan, students explore calories, pulse rate, and the circulatory system. Students use mathematical data to create a healthy physical...

Learners create an exercise and nutrition program. For this interdisciplinary lesson, students use calculations of exercises plus their corresponding effects on the body and nutritional values of food to derive a health plan. Learners...

Students discover that proportions are made up of equal ratios each containing the same building blocks. They, using the Internet, apply their knowledge of direct relationships and proportions to problems in planetary science.

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.
