There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Students discover the relationship between the circumference of a circle and its diameter. They find the length of an arc of a circle.Students use estimation strategies in real-world applications to predict results (i.e., interpolation...

Formulas and procedures for finding the area and circumference are not provided on this handout, so it will be best used as a practice of already-acquired skills. It is a well-rounded assignment, however, as it includes diagrams,...

Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; learners use grids to make and explain estimates within low and high ranges.

Shapes are so fun! Little ones explore, identify, and create shapes using tangrams or pattern blocks. The activity is intended to stimulate critical thinking while engaging learners through play and shape identification. Each child will...

Students explore the concept of area under a curve. In this area under a curve lesson, students find the area under a curve using the Monte Carlo method using random points and probability. Students calculate the area under the same...

Young scholars build nets of three-dimensional prisms based on the dimensions they are given for hexagonal prism, triangular prism, rectangular prism. Working in groups, they use their prisms and calculate the Surface Area and Lateral Area.

In this cylinder worksheet, students compare three different cylinders to experiment which one has the greatest volume. Students interact with rectangles as they experiment with the cylinders.

In this similar figures worksheet, students identify the meaning of similar, corresponding sides, and congruent.  They use proportions to find the length of a missing side.  Students dilate given figures according to a scale...

In this polygon area worksheet, students answer 8 questions involving the area of several polygons. Students are given various details of the polygon and must find lengths of various polygons.

Third graders explore vocabulary associated with three dimensional figures.  In this transformations instructional activity, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with...

In this geometry worksheet, students investigate the missing side of  triangles given the other two sides. There are 5 questions with a solution key.

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson plan, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional...

Learners explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Third graders design and make clocks compiling a materials list, creating adesign portfolio, and recording progress in a daily log. After making a full-size drawing of their clocks and with the assistance of high school technology...

Students, in groups, determine the volume of a box large enough to hold a million dollars. They calculate the dimensions of a bill and the volume of the money.

Students explore pentominoes in this activity. They build shapes as directed and color the tiles on their grid sheet.

Students demonstrate the process of creating a scaled rubber band enlargement of a simple drawing. They observe and discuss a teacher-led demonstration, and create a scaled rubber band enlargement of simple drawings and their invention...

Students collect and record data. In this early data analysis lesson, students gather data about their partners face. As a class, the students use tally marks and pictographs to record the data and answer question about the information...

Find the length of an arc. Students relate central angles to the area and length of a sector and graph circles on the TI to make predictions.

Fifth graders throw darts, collecting data for distance traveled. For this data analysis lesson, 5th graders throw a dart using an atlatl. They calculate the speed for each throw and determine the best dart length for distance throws.

Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...

Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.
