Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

Elementary graders discover the concept of fractional pieces of a whole. They investigate the meanings of fractions in everyday life and why they are used. Pupils divide brownies amongst each other to demonstrate the use of fractions...

Your middle schoolers will show what they know with their bodies when they become the coordinate plane in this conceptual development unit. Starting with the characteristics of the coordinate plane, learners develop their skills by...

Use coordinate grid paper to plot points and identify shapes that are already plotted on the paper by saying their coordinates. Pupils also measure the distance between points and play the game Battleship. There are several web links and...

Perform operations to add, subtract, multiply and divide matrices. Then solve problems with vectors using matrices. A three day instructional activity: Matrix Madness, Mystical Matrices, and Decode the Encode. The last instructional...

Pupils in grade 7 and 8 work on outcomes related to spatial sense and geometric concepts, properties, and relationships. The instructional activity integrates technology and helps students be exposed to multimedia.

Fourth graders, using a straight edge, determine whether a point is inside or outside of a given figure. With worksheets, 4th graders practice analyzing geometric relationships such as parallel to, perpendicular to, etc.

Young scholars examine tesselllations and their geometric properties. They have a better knowledge of polygons, can identify types of symmetry in tessellations. Also students use visulization, spatial reasoning, and geometric modeling...

Students explore circumference and diameter. In this math lesson plan, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of...

Pupils explore weight. In this math lesson, students predict which item weighs more and discuss how they arrived at their decision. Pupils weigh several items to determine which weighs more.

Students use Cartesian coordinates or degrees of latitude and longitude to locate important locations within their specific countries. They Use a grid to apply the concept of latitude and longitude, or positive and negative Cartesian...

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

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:...

Am I making any money? Help learners determine if their fictitious soda stand is turning a profit. They graph linear equations using the slope and y-intercept and identify the best price to use to sell soda. They identify the domain and...

Students examine how Earth's rotation causes daily cycles in solar energy using a microset of satellite data to investigate the Earth's daily radiation budget and locating map locations using latitude and longitude coordinates.

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 would be an excellent choice for...

Explore the solution to a word problem involving area and perimeter. Learners read and discuss how to approach the problem. In small groups, they determine the maximum area of a rectangle with a given perimeter using a piece of string....

Students examine the built environment and infrastructures of their community by constructing contour equipment, using the equipment, and comparing their results to current topographical maps of the same area

Young cartographers in groups hide treasure at school and then create a map to find it using pattern blocks and tiles. They make paintings with clues to create a visual representation of the location of their treasure. Groups present...

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this lesson. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is by viewing a...

Learners of all ages investigate area and perimeter through pentominoes. In this geometry lesson plan, students calculate the are and perimeter of different geometric shapes and describe the properties of similar and congruent shapes....
