Your learners will be tantalized by this inquiry-based, collaborative activity as they discover how to write an equation that represents the height of an ice cream cone. Given the scenario based on the poem, "Eighteen Flavors," and...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Fourth graders use manipulatives to practice math patterns.

Excellent instructional activity! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump...

Through the use of Internet, video, and hands-on activities, youngsters learn the parts and characteristics of a circle. This fantastic activity has some excellent website activities included in the plan. Your kids will have a much...

Second graders create a shape garden. In this polygons lesson, 2nd graders practice making shapes using a geoboard and read the book The Greedy Triangle by Marilyn Burns.  Students also design a shape garden using construction...

Students discover which regular polygons can be used to tile a plane.

Students review angles, sides, and properties of basic shapes. Using a geoboard, they make as many different tirangles as possible.

Students read The Greedy Triangle and discuss geometric solids. In this geometry lesson plan, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands...

Students explore geometric solids. In this geometry lesson, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric solids...

Students discuss figures with various numbers of sides.  In this geometry lesson plan, students are read The Greedy Triangle by Marilyn Burns, they participate in a class discussion of many sided figures and are introduced to the...

First graders listen to Shapes and The Greedy Triangle to identify and describe examples of geometric shapes.  In this geometric shapes lesson, look for geometric shapes in real world places.  Students make a mobile of shapes...

Third graders discover geometric shapes by completing a series of games and activities. Using ropes with knots tied every foot, they make shapes such as squares, triangles, and hexagons. In pairs, 3rd graders use pattern blocks to...

If shapes have the same area, do they always have the same perimeter? Learners explore the relationship between the area of square units and their perimeters in a hands-on activity. Observations are recorded, and they begin to recognize...

Sixth graders identify various angles by using pattern blocks. For this measurement lesson, 6th graders find out how many degrees are in each of the different angles of the various pattern blocks.

Young scholars explore geometry by participating in a school measuring activity. In this perimeter lesson, students discuss the techniques and methods used in order to measure a large perimeter or geometric figure. Young scholars utilize...

Young scholars complete activities to learn about the shapes and their vertices. In this shape recognition lesson, students discover the rule linking the number of sides with the number of vertices for shapes. Young scholars categorize...

Students brainstorm and discuss ways math is all around them, explain in writing how they solve math problems, describe mathematical ideas in writing, and create original story problems.

Third graders use addition to create numbers that are palindromes and organize their results to look for patterns. They make generalizations from patterns and practice reading large numbers and addition with regrouping.

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...

Fourth graders participate in what is considered to be a model lesson. The lesson focuses upon polygons and basic geometry. The lesson addresses national standards and displays how others should be done.

Third graders work in groups of two to three with measuring tapes, finding the circumference and diameter of teacher-selected circular items. They relate circumference and diameter measurements to find pi.

Young learners listen to the story book The Greedy Triangle as the teacher introduces new polygon shapes. They use geometric stencils to trace a quadrilateral, a pentagon, a hexagon, and an octogon onto a foldable notepad....
