Students complete a two-week unit involving design and construction concepts. They watch a PowerPoint presentation about geometric shapes, draw the fourteen shapes incorporated in bridge construction, and in small groups design, build,...

Students record reaction time data and calculate minimum, maximum, mean, median, and mode. They participate in a class reaction time activity, observe and conduct an online experiment, and discuss and analyze the activity results.

Fourth graders identify and classify different triangles and quadrilaterals. Then they demonstrate an understanding of plane and solid geometric objects and use this knowledge to show relationships and solve specific problems. Students...

High schoolers construct perpendicular bisectors using Cabri Jr. on their graphing calculator. They then construct conditional statements about perpendicular bisectors along with their converse, inverse, and contrapositive.

Learners use technology to determine the shortest between two points in a plane. They are required to support their analytic explanations with visual illustrations.

Learners investigate the area of various figures. They construct triangles and quadrilaterals using Cabri Jr. and discuss the relationships between different angles, side lengths, and figures.

High schoolers explore the concept of quadrilaterals as they find the midsegments of quadrilaterals using Cabri Jr. on a graphing calculator. They find midpoints, slopes, angles, and distances of lines and angles.

High schoolers investigate properties of the four centers of a triangle and explore a special property of the circumcenter and orthocenter of a triangle. This lesson requires the use of Cabri, Jr.

In this Apollo-11 landing site worksheet, students read about the NASA Lunar Reconnaissance Orbiter (LRO) that will collect images at a higher resolution than ever before. Students study a grid showing the lunar landing site from Apollo...

Students relate Pi to a circle. In this circles lesson, students identify the different properties of two dimensional objects. They relate Pi to the circumference, diameter and area of a circle .

Students design charts, tables, graphs, and pictographs to analyse the types of snacks in a bag.

Eleventh graders research quality of life indicators for a list of countries looking at such things as infant mortality rate, and gross domestic product. They rank the countries from best to worst regarding quality of life issues.

Students create different shapes by putting light on different objects. They change the distance from the object, the light source and angles to make the shadows different. They are to describe the relationship between the light, object...

Sixth graders view a Stacked Graph, and discuss what it shows. Students discuss the basics of graphing: labels, intervals, legends x and y axis... Students create individual stacked graphs from provided information. Students view a...

Students form "companies" of 3-4 students and build bottle rockets for analysis and experiment. This lesson uses NASA's RcketModeler Version 1.2 rocket simulator to evaluate each rocket's flight.

Learners define the term species, and graph species data together with previously collected data at the National Zoo. They interpret graphed data and recognize patterns in the streamside quadrant versus hillside quadrant. Students use...

Learners engage in a lesson plan that is about the classification of triangles and the mathematical proofs involved in working with them. They work on a variety of problems that are created by the teacher with the focus upon the...

Students explore pentominoes in this activity. They build shapes as directed and color the tiles on their grid sheet.

Students examine the lines of latitude and longitude on a map, and explain why these lines might be useful. In this lesson students also explore websites that provide information to improve their understanding of how and why latitude and...

Seventh graders recognize the characteristics of isosceles triangles. In this isosceles triangle lesson, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.

Learners explore the International Monetary Fund (IMF). In this global economics lesson, students prepare for a field trip to the IMF as they examine the history of the IMF and their role in global trade.

Young scholars gather data on sports team and create a box and whisper plot. In this data collection lesson, students find the median, the quartile range, and relationships between variables.

Eleventh graders explore quadratic equations.  In this Algebra II lesson, 11th graders use Geometer’s Sketchpad to explore the properties of quadratics and the connections with polynomials and linear equations.  The lesson is...

In this algebra worksheet, students solve linear equations using one and two steps. They solve systems of equations using substitution and elimination with graphing. There are links for ready made tests and quizzes.
