Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson. They make a set of tangrams and use them to compute area. They use...

Review and use standard units of measure with your math class. They move from station to station estimating and measuring length, volume, weight, and area. At each station they estimate and measure, and then compute the difference...

Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...

Let imaginations run wild as participants design animal pens. A performance task challenges young mathematicians to determine the perimeter or a missing side length of different animal pens. They then design pens that meet given...

Practice finding the area of squares and rectangles. Complete with a grid for third graders to measure each side, this resource will be helpful. Though the shapes vary in size, they all have four sides to make measurement easy. Pupils...

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

Fourth graders practice calculating area by creating a classroom quilt. Students are given a 6x6 inch square material they design based on a classroom theme. A sample of the class quilt is created using graph paper so students may...

An engaging hands-on activity is presented. Learners of all ages are addressed in thie unique plan. K-5 learners identify, name, and define a rectangle, square, triangle, and the concept of area. Older learners prove the Pythagorean...

Sixth graders design rectangular gardens with a given perimeter and generalize how to maximize the area Students applying the formulas for perimeter and area of polygons. They analyze length, area, and volume and make relationships...

There are many ways to work through a multiplication problem. Using an area model, kids complete several worksheets with different types of multiplication problems, including multiplying by ten, and explain how the new strategies differ...

Individuals learn to apply the Euclidean algorithm to find the greatest common factor of two numbers. Additionally, the lesson connects greatest common factor to the largest square that can be drawn in a rectangle.

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Need to build a laser fence on Mars?  In this cute maximizing-area lesson, young explorers pretend to be prospectors on Mars and must determine the best way to use 20 meters of fencing in order to maximize their area. In addition,...

Expose youngsters to 3-D objects in a hands-on learning activity involving marshmallows and toothpicks. Engage your young mathematicians by introducing them to 3-D shapes by means of a story book. Explore 3-D shapes by manipulating...

Young scholars examine geometric quilt patterns to identify how math may have been used to help slaves escape to freedom. They slide, flip and turn geometric shapes to create a map quilt.

Get your youngsters using rules! For this challenge, they measure the shapes that make up a house and a tree to practice measuring in centimeters. Then, they write down the equation for each shape. (Example: 4+6+4+6.) Finally, they...

A nice presentation on how to calculate area awaits your 5th graders. The interactive component is quite good. Learners view a variety of shapes on a grid, calculate the area, and type in what type of polygon it is. Some effective...

Puzzling over what geometry lesson to teach next? Look no further. This simple activity teaches young mathematicians how shapes can be decomposed into smaller figures, and how smaller figures can be assembled into larger shapes. To learn...

This geometric pattern will appeal to learners' artistic sides as they color various shapes based on a guide: they color circles blue, triangles red, squares green, and rectangles yellow. What does this finished design remind scholars...

This two-part reading comprehension exercise asks kids to read a short passage about cubes, rectangular prisms, spheres and pyramids, and then to respond to a series of questions about the article.

As you introduce graphs and coordinate pairs, use this guided activity to get scholars started. They reference an example before recording number pairs to identify the location of 12 letters on a grid. Next, learners examine shapes on a...

Create geometric cups by interpreting directions, informational text, and mathematical concepts. Critical thinkers apply geometric theory (congruent shapes, patterns, symmetry) to actual directions to create a cup that holds Kool Aid....

In this algebra instructional activity, mathematicians identify important vocabulary related to solving equations. They create and simplify expressions and solve word problems. There are a total of 10 questions that provide a good review...
