Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Learners analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationship

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...

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This lesson plan gives students a meaningful way to practice these...

Students use an online dictionaries to define key geometric terms. They explore several websites to help them differentiate the terms reflections, translations and rotations as they apply to geometry and then complete an assessment...

Students investigate proofs used to solve geometric problems. In this geometry lesson, students read about the history behind early geometry and learn how to write proofs correctly using two columns. The define terminology valuable to...

Students determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and theorems.

Students explore graphing. In this math lesson plan, students graph ordered pairs in the coordinate plane, write the coordinates of points shown on a plane, and create designs or pictures using ordered pairs.

Sixth graders complete several activities that involve coordinates and graph paper. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders draw and label a coordinate...

In this volume worksheet, students calculate the volume by finding out how many units each figure has. Students complete 4 problems where they find the volume.

Fourth graders are introduced to the vocabulary needed to identify the attributes of two and three-dimensional figures. They work together to create a word wall, which contains the geometric terminology being learned.

Students identify triangles in the real world and construct their own triangle using drinking straws. They explore abstract triangles and find additional geometric shapes such as trapezoids. Students discuss similar shapes and examine...

Learners explore the Math Dictionary for Kids site (see Weblinks). (They will discover the second set of terms is synonyms for the first set.) The teacher observes students' progress and provides feedback to learners as they work at the...

In this shape and figures worksheet, students read descriptions of shapes and figures, name them and draw their pictures in spaces provided. A reference web site is given for additional activities.

In this shape and figure worksheet, learners name shapes or figures that are described, then draw a picture of each. A reference web site is given for additional activities.

In this shape and figure description worksheet, students read a description of a shape, name the shape and draw it, 2 total. A reference web site is given for additional activities.

In this shape and figure worksheet, students read a description of a shape, name it and then draw it, 2 shapes total. A reference web site is given for additional activities.

Solve story problems using fractions or decimals. Then, determine the reasonableness of answers using estimation.The detailed lesson plan includes essential questions, vocabulary, a materials list, and links to related units.

Students investigate properties of circles. For this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.

Compare two- and three-dimensional shapes and construct three dimensional models from two-dimensional shapes. Diagram the shapes and reflect about the process in writing.

What type of corners does this shape have? Young geometers examine 12 shapes, circling the square corners in each if they have any. There are two examples demonstrating this concept, but be sure scholars understand the difference between...

Build a scale model of a home built out of shipping containers. A hands-on activity has scholars watch a video about a home built from shipping containers and then design their own home. They build scale models of their designed homes...

Use your pupils' sense of curiosity to explore the Parallelogram Law. Here is an activity that outlines a complete lesson from beginning to end, allowing pupils to follow a conjecture through to the proof stage.

Second graders explore symmetry and congruent shapes. In this math lesson, 2nd graders identify examples of symmetry and congruent shapes in nature. Students take photographs and create a multimedia presentation of symmetry and congruent...
