Develop a model for a hanging chain. Pupils find a mathematical model for a hanging chain and then they compare their models to the precise function that models the curve. Scholars come up with a strategy to determine how close...

While the lesson focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can they...

Open up your pupils' eyes and minds on dilations. Scholars perform dilations on a trapezoid on the coordinate plane. They compare the image to the preimage and develop generalizations about dilations.

Students use pattern blocks to create a figure that is described to them and establish a pattern based on the description of the geometric figure. For this pattern blocks lesson plan, students fill out shape and fraction worksheets.

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...

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Students observe how certain geometric shapes can be used to make some structures rigid and others flexible. The activity involves construction of a 30-60 right triangle, folding while following directions, and identifying polygons.

Eighth graders plot points and investigate polygons. They locate a point, using ordered pairs of integers on the coordinate plane. Students compare geometric measurements and computations on coordinate axes as they are applied to...

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...

Students identify symmetry in road signs. In this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.

Students brainstorm names of plane and solid geometric figures. Afterward, they explore the skyline of large cities and note their agricultural shapes. Using construction paper, students build 3-D geometric structures to create a skyline...

Students review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.

Fifth graders use estimation to solve word problems. In this fractions lesson, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation. This lesson...

Seventh graders investigate some concepts associated with geometric shapes. They study the bisector segment and the perpendicular line to a given line. Students conduct analysis with the goal of deepening observation and deduction...

Second graders explore triangles and quadrilaterals. They rotate to various centers in the room to identify and examine triangles and quadrilaterals. After presenting a picture to the class, 2nd graders locate right angles, triangles...

In this tessellations instructional activity, 10th graders solve 6 different types of tessellation problems that includes drawing. First, they define polygon, regular polygon, tessellation, regular tessellation, and semi-regular...

In this patterning worksheet, 1st graders complete 4 patterns that are formed of black line pictures of plane figures. They trace the figures in the first example and draw the figure that complete the patterns in the last 3.

Young scholars investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Young scholars identify the different types of polygons and define...

Second graders explore the features of triangles and quadrilaterals. In this lesson on triangles and quadrilaterals, 2nd graders rotate with their group to five different activities all exploring a different aspect of geometry.

Students identify the types and characteristics of geometric figures. For this lighthouse geometric lesson, students review shapes that represent plane or solid.  They select items that could be used to construct a lighthouse scene...

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

Students explore the concept of geometric shapes. In this geometric shape lesson, students play bingo to review geometric shapes. Students identify the shape being described by the teacher and put a marker on their bingo card.

In this shoelace algorithm worksheet, students determine the area of a triangle when given the coordinates of the vertices. They determine the area of a quadrilateral. Students find the average of the x and y coordinates.

Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...
