Sharpen your pencil and grab a ruler, it's time to draw some quadrilaterals! Given the definition of a parallelogram, rectangle, and rhombus, learners draw examples and nonexamples of each figure. The three definitions are...

All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create...

Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...

Young learners will view a math adventures video and practice math concepts.  Afterwards they will navigate through Internet sites to participate in teacher selected math adventures. This guide walks you through integrating...

Kindergartners listen to a story read by their teacher, then use magnetic shape pieces to construct simple designes. They "build" their own house using pre-cut paper shapes. This age-appropriate lesson plan would be an excellent choice...

Second graders explore and analyze plane shapes. In this plane shapes lesson, 2nd graders evaluate shape attributes to classify shapes correctly. Students work in groups to create different shapes.

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

Learners find out the meaning for prefixes used in math vocabulary. By dissecting words used in everyday math, they figure out what the prefix indicates and what the word means. A variety of well-organized worksheets and activities...

Kindergartners are introduced to basic shapes. Learners spend 45 minutes a day in geometry centers carrying out the activities outlined in this ambitious plan. There are games, hands-on activities, interactive websites, art projects,...

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

Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...

What can symmetry tell us about triangles? After looking at four examples, learners will come to realize that lines of symmetry are different for equilateral, isosceles, and scalene triangles. Use this guided practice activity as an...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Excellent lesson plan! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump ropes),...

Students sort objects by shape, size and color. For this math and literacy sorting lesson, students listen to the book Freddy the Fish and the Squash that Goes Squish by Duke Christoffersen. Students work in small groups to sort...

First graders examine how to sort concrete objects by their attributes. In this sorting lesson, 1st graders listen to Gray Rabbit's Odd One Out by Alan Baker, and discuss the actions of the main character. They practice sorting objects...

Students explore geometry by utilizing computer software. In this shape identification lesson plan, students define several geometric shapes by the characteristics that classify them. Students draw and cut out geometric shapes using...

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

Students discover how to classify and categorize items by sorting various objects. As they sort the items, they explain how the items are alike. By repeating the sorting procedure several times, students determine there are numerous...

Young scholars use their math skills of sorting and classifying with materials they collect outdoors. In this early childhood math lesson, students participate in a treasure hunt to gather item in nature and categorize their finds.

Students explore measurements by analyzing geometric shapes. In this surface area lesson, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students utilize...

Learners classify and compare plants using specific information, observations, and numbers. In this mathematical inquiry lesson, students use plant characteristics to describe, compare, and classify them. They attempt to develop a system...

Junior geologists sort rocks and soil. They separate a sample of river gravel by size, shape, color, and other characteristics. To include Common Core standards, you could have little ones graph the number of particles in each sample.

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...
