Students prove conjectures about geometric figures on the plane or in space using coordinate geometry. They develop fluency in operations with real numbers, vectors and matrices using mental computation or paper-and-pencil calculations...

Fifth graders examine the partial-quotients algorithm for finding the answer to a division problem.  In this partial quotients lesson, 5th graders demonstrate the process of division through a series of estimations....

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.

This lesson requires a worksheet that is not connected. It is integral to the lesson.

Learners analyze the amount of space required to pack round objects. In this geometry instructional activity, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to...

Fifth graders connect their knowledge of polygons and polyhedrons. For this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

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,...

In this finding the sums worksheet, students add one digit-numbers plus two-digit numbers with no regrouping. Students solve 30 problems.

In this addition worksheet, students fill in the missing addend to an addition problem that adds up to 30. This number could be a one or two digit number. Students complete 41 missing addend problems.

In this identifying numbers that total fifty instructional activity, learners use an addend and the sum fifty to write the missing number. Students solve 41 problems.

In this addition worksheet, students fill in the missing addend for problems that add up to 100. Students complete 41 problems.

Middle schoolers examine and compare traits of humans and crocodiles.  In this crocodile instructional activity students use a ratio to estimate the height of a person and compare that to a crocodile. 

Students conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...

Students record scientific observations in a science journal.  In this season instructional activity, students make observations about each of the seasons and record in their journals.  Students record organisms response to...

Young scholars investigate the engineering design process and the relationship between distance, time, and speed. Using a generic car base, small groups design a device that will protect an egg on or in the car as it is rolled down a...

Students become familiar with how to get information from the Internet. In this math and technology lesson plan, students measure objects on a measurement sheet found on a web site. They practice using a standard unit of measurement...

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson plan, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional...

Learners gain an appreciation of the polygons and polyhedrons around them that make their world one of order and strength. They build polygons and polyhedrons, and then construct airplanes out of polygons.

Students review the conversion of fractions to decimals, develop strategies to compare fractions perform complex calculations using ratio techniques similar to the construction of fractions.

High schoolers determine an appropriate numerical representation of a problem situation, including roots and powers. They determine an appropriate number of digits to represent an outcome. Pupils are asked to determine how many years...

Young scholars investigate polymers by completing 3 experiments. In this polymer lesson plan, students mix plastic with acetone, they create polyurethane foam, they make slime and build a polymer model once their polyurethane foam is...

In this division worksheet, students solve algebraic problems containing fractions. This one-page worksheet contains 11 problems. Answers are provided. This worksheet may be completed on-line or produced in printed form.

Students analyze objects by one or more attributes. In this sorting lesson, students use manipulatives and string or yarn to create a sorting game. Students read books and items from the classroom to sort.
