In this geometry lesson, learners read The Greedy Triangle and use geoboards to construct geometric shapes. They identify the number of sides and angles each shape has.

Grab some marbles from a bag. The applet simulates drawing marbles from a bag. Pupils determine the number of four colors of marbles in a bag and how many marbles to draw. Using information on whether order matters in the draw and if...

Investigate the area and perimeter of polygons in this geometry lesson plan. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape...

Students brainstorm words that describe the weight of objects. They pick up objects and estimate the weight. Afterward, students find the exact weight and compare U.S. units of weight to metric units. In groups, students create a chart...

Students listen to the book, "The Grouchy Ladybug" by Eric Carle and sequence the events in the story. Using a graph, they draw and color the animals that the ladybug meets next to the corresponding time from the story, and conduct...

Learners determine the number of pennies needed to fill a room.  In this pennies lesson plan, students work in groups to determine the number of pennies needed to fill a room.  They compute the probability of the head of a pin...

Mixing math and art is done in this lesson by applying graphing knowledge to create a unique piece of art. This lesson varies acording to the graphing knowledge of the artist. First, learners identify and review various types of graphing...

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

It's all about the patterns! Young scholars learn that the unit circle repeats itself in all four quadrants. Using these patterns, they evaluate the sine, cosine, and tangent of special angles.

Learners practice problem-solving with this addition activity. They plan a party for their class and another class by determining how many cupcakes are needed. Students draw a picture of how they determined the number of cupcakes.

Young scholars draw a ship to scale, and calculate the real life size. They show that measurements on the drawingsare annotated with the distances reported in inches (fractions and decimals), and their real-world equivalents

Students design a ship. They calculate square footage and draw their ship to scale. They build models of their ships.

Students explore the concept of geometric symmetry. In this geometric symmetry lesson, students walk around their school and take pictures of objects that demonstrate symmetry. Students use Microsoft Paint to draw the lines of symmetry...

Students explore the concept of polygon properties. In this polygon properties instructional activity, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different...

A fabulous lesson which combines mathematics with space science. Middle schoolers work in cooperative groups in order to research early astronauts and their accomplishments. They look at a variety of rocket and space shuttle designs, and...

Approach addition with young mathematicians in an engaging way through this penguin-inspired activity. In small groups, scholars think about times they have used addition in their real lives (there are some suggestions given), then watch...

Young scholars analyze data through graphs. They will complete a class survey on ice cream sundaes and tally and graph the responses. They then analyze the information from the class graph.

Math novices examine how math can help them in real-world situations. They listen to the book The Math Curse by Jon Scieszka, solve various word problems from the book, explore various math websites, write original math word problems,...

Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...

No height? No problem! Learners use their knowledge and a little help from GeoGebra to develop the Law of Sines formula. The Law of Sines helps to determine the height of triangles to calculate the area.

Examine commutative and associative properties with your class. They'll explore the relationships between addition and subtraction and investigate patterns as they solve addition problems. Links to an assessment and a table game are...

What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Third graders listen to a read-aloud of Leo Lionni's, Inch by Inch before measuring a variety of items using both standard and metric units. They record the measurement data and follow a recipe for dirt pie.
