Sixth graders design rectangular gardens with a given perimeter and generalize how to maximize the area Students applying the formulas for perimeter and area of polygons. They analyze length, area, and volume and make relationships...

Try five problems on triangles. Levels A and B focus on shapes that can be created from right triangles. Level C touches upon the relationship between the area of a six-pointed star and the area of each triangle of which it is composed....

Most middle schoolers probably feel that quilting is at best an activity left to their grandmothers. This instructional activity uses the Zome modeling system to get them to realize how shapes in quilting are really tessellations and...

Fifth graders demonstrate the concept of perimeter and area using manipulative. In this area and perimeter instructional activity, 5th graders explore area and perimeter through the exploration style of teaching using eatable and...

Fifth graders examine how to make tessellations. In this tessellation lesson, 5th graders review the meaning of the word "polygon" while the teacher shows them various examples. They practice making tiling patterns or tessellation's with...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Elementary schoolers are arranged in pairs and view the video Math Works: Measurement: The Difference Between Perimeter and Area. They discuss any prior knowledge they have of the term perimeter and then brainstorm together what the...

Third graders create polygons with perimeters of 30 centimeters, use the centimeter grid paper to determine the area of each shape, and organize the shapes to make generalizations from the patterns they see.

Here is an excellent cross-curricular instructional activity. Learners relate multiplication to area by making a grid on graph paper, and then creating the same grid in real space outside in the school yard.

Go on a scavenger hunt around your school to find evidence of math. Investigate different areas of your school for patterns, fractions, and different geometric shapes. Finally, create a spreadsheet and plot the data you've collected.

Third graders are given square tiles and participate in a demonstration on how to arrange them. Using the tiles, they work with a partner to discover how many two-dimensional tetrominoes they can create. To end the lesson, they must...

In this interactive lesson, learners review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create tessellations. They...

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Students experiment with varied balls to determine the bounce factor in centimeters. In this physics lesson, students experiment to find the height a ball must be dropped from the have the highest bounce rate. Students graph the results...

High schoolers explore the concept of quadrilaterals. In this quadrilateral lesson plan, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids,...

Students use tiles to find area. In this finding area instructional activity, students explore how to use square tiles to make shapes, then look at how they can be used to measure area. Students then explore how an area can be covered...

Students investigate the geometrical concepts of translation, reflection, and rotation. They make different observations looking for the concepts that are displayed in classroom items like floor tiles, carpet designs, and visuals hung in...

Students investigate acoustical ceilings.  In this acoustical ceilings lesson plan, students construct a blueprint for an acoustical ceiling.  Students use area and perimeter of rectangles to construct their blueprint. ...

Young scholars calculate the area of different polygons. In this geometry lesson, students explore polygons based in their shape and number of sides. They find the formula for the area and use each specific formula for each shape.

Students explore geometry by participating in a pattern identification activity. In this tetrominoes lesson, students define the characteristics of congruent and symmetrical shapes. Students practice translating shapes across quadrants...

Young scholars identify shapes that will tessellate. They construct a tessellation using transformations. Students identify transformations in tessellations. They identify applications of transformations such as tiling and fabric design.

Young scholars create a rectangular garden using paper and tiles. In this geometry lesson, students investigate the largest possible rectangle that can be created given specific boundaries. They use grid paper to draw the rectangles...

Young scholars investigate shapes and patterns. In this algebra lesson, students move from concrete to abstract understanding of shapes and concepts. They use variable to identify the unknown.

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