Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...

Math scholars study conics and how they are used today. For this mathematical lesson, pupils construct and slice cones after viewing a demonstration. 

This task includes scaffolding to support the introduction of the writing and graphing of linear inequalities. Then your geometry learners discover that writing down all possible combinations is not feasible so they are led to use...

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

Zero in on an interesting resource involving radar technology. Groups construct a radar sensing unit and learn to calibrate the system. Using the radar system and the Pythagorean Theorem, they calculate distances between objects.

Tenth graders investigate geometric construction.  In this geometry lesson plan, 10th graders explore the procedure for copying an angle and a segment.  The lesson plan emphasizes the difference between a sketch, a drawing, and...

Third graders construct a dodecahedron that displays facts about two and three-dimensional figures. They use a pattern to construct a dodecahedron after writing facts about geometry onto each of the figure's twelve faces.

Students create building and models using scale factors. In this geometry instructional activity, students apply the properties of ratio and proportion to solve problems. They identify the means and extremes property of cross...

Students use specific dimensions to create a box. In this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Fifth graders explore geometry by creating shapes with construction paper. In this shape characteristics lesson, 5th graders identify the different attributes that make up specific shapes and create them using construction paper, rulers,...

Students create polygons using geometers sketchpad. In this geometry lesson, students construct the interior angles of polygons and label the different points. They estimate and measure the different parts as they draw conclusion.

Fourth graders identify lines of symmetry using reflections and then construct figures that have one or more lines of symmetry. In this symmetry lesson plan, 4th graders use sets of shapes, pattern blocks, a mirror, and more.

In this geometry worksheet, students create a map that uses various geometrical concepts. The final project is the creation of a "geometrical town." Rubric for grading is included.

Third graders explore the attributes of polygons. In this geometric shapes lesson, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons. Students then...

First graders explore 2-dimensional and 3-dimensional shapes. In this geometry lesson, 1st graders examine the attributes of 2 -dimensional and 3-dimensional shapes. They also create the shapes as they build models. This lesson...

Fourth graders explore geometry by utilizing pattern blocks. In this pattern lesson, 4th graders analyze two separate pattern block shapes and discuss which one is bigger and smaller. Students collaborate in small groups to create...

Students explore geometry by participating in a measurement activity. For this human anatomy lesson, students identify the appropriate methods to measure human body parts and do so in class. Students create a bar graph from their class...

Young scholars investigate architecture and construction by building a home from cardboard tubes.  For this housing lesson, students collaborate in groups to plan and create buildings they can fit in made from cardboard tubes,...

Middle schoolers apply various methods for finding the volume and surface area of sphere. They compare and contrast results among these mathematical methods. They work in cooperative groups to discuss their results with one another.

Students explore the architecture of New England by identifying geometric shapes.  In this architectural lesson, students examine photographs of classic building architecture and use a transparency to trace geometric shapes they...

Fifth graders examine the many uses of coordinate grids. In this graphing lesson, 5th graders write data driven equations, discuss the x and y-axis, and determine if using 2 or 3 ordered pairs is better.  Students complete several...

This is a nice hands-on activity where young geometers create trapezoids and calculate their area by looking at areas of quadrilaterals and triangles. 

Pupils, in groups, construct different angles and shapes on a large scale using string and chalk.

Tenth graders construct geometric figures using compasses and protractors.
