Students model and solve a real-world problem by constructing the centroid of a triangle. They explore relationships of the medians of a triangle and investigate how the centroid partitions each of the medians. Students investigate...

Students practice recognizing shapes while using gross-motor skills. In this early childhood math movement lesson, students explore shapes as music plays and they walk the perimeter of large cut-out paper shapes by playing musical squares.

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Using their knowledge of right triangles, pupils find out how far a ship is from a light house. Class members determine how far around the world a ship would be sailing at a constant speed.

Lesson 16 is just another day of practice in preparation for the class soccer World Cup. There is a pretty involved warm-up activity called Flag Drag Tag. The skills of tag, running around and trying to stay away from taggers is a...

Introduce the procedure needed to find the volume of a rectangular prism. Learners rank various prisms such as cereal boxes and tissue boxes from smallest to largest volume. They use an applet to find the volume and surface area of each...

Students examine the characteristics of an ecosystem. They create their own landmass of an ecosystem and creating a map of the area. They develop a brochure sharing information about their new landmass.

There are actually several math topics covered by this set of problems. First is the addition of fractions and mixed numbers with both like and unlike denominators. Nine word problems are provided after some whole class practice.There...

Seventh graders research the World Wide Web to research and plan a garden for their school. They draw a scale model of the garden, determine the cost, and create a presentation to promote their garden plan.

Eighth graders solve real world problems.  In this solving real world problems lesson, 8th graders decorate a school cafeteria for a dance.  Students determine the number of balloons needed to put a balloon every foot for the...

Fifth graders practice, with spreadsheets, to demonstrate how to determine the number of tiles needed to create a patio. They use pictures and gathered data to determine a pattern that can be used to solve problems. Students create a...

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Young scholars explore angles and their use in Geometry. Students investigate three different kinds of angles: obtuse, acute, and right angles through an online activity. They identify pairs of angles with special relationships:...

In this fractions instructional activity, students solve 10 short answer problems. Students find items around their home and weigh them. Students convert units from one unit to another in the customary system.

Thirty seconds are all scholars have to develop an engaging commercial to showcase their talents and experience within a specific occupation. Pairs work collaboratively to keep each other on time to deliver information speedily and ask...

Students explore energy usage in home and in school. They examine the types of non-renewable sources and discover alternate sources of energy. Through group activities, students calculate the perimeter and area of a given room. They make...

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

Students, after reviewing the measuring of the lengths of sides of different shapes along with the calculation of their perimeters and areas, encounter what it means by the 'perimeter' of a polygon. They practice measuring units of...

Young scholars identify basic geometric shapes using Geogebra. In this geometry lesson, students work on a laptop as they explore different geometric shapes. They calculate the area and perimeter of triangles.

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

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

In this inequalities activity, 10th graders solve and complete 23 various types of problems. First, they find the area of an inscribed square in a circle shown. Then, students find the total area of the inscribed polygon and deduce...

Students observe and gather data from a model simulated home.  In this efficiency lesson students examine the factors that influence energy efficiency, complete a lab activity then draw conclusions from their data.
