After determining the volume of various drinking glasses , class members evaluate sample responses to the same task to identify errors in reasoning.

Break out those math manipulatives, it's time to teach about area! Capturing the engagement of young mathematicians, this three-lesson series supports children with learning how to measure the area of squares, rectangles, and other...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Take young scholars on a trip through history with this unit on the mathematics and architecture of the Mayan civilization. Starting with a introduction to their base twenty number system and the symbols they used, this eight-lesson unit...

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...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

Third graders consider space and the techniques artists use to create three-dimensionality within a painting or drawing. They examine works by Millet, Bruegel and Demuth and then create original drawings that explore the effects of...

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Students examine various closed and open figures. They decide which letters have closed figures. Then they receive a pre-made name card and decorate every closed figure in their name.

Third graders are given square tiles and participate in a demonstration on how to arrange them. Using the tiles, they work with a partner to discover how many two-dimensional tetrominoes they can create. To end the lesson, they must...

Third graders engage in a lesson that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while following the...

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...

Students explore models of three-dimensional shapes. In this geometric shapes lesson, students use hands-on manipulatives to explore three-dimensional shapes. Students predict whether each shape will roll or slide.

Young scholars 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...

Fifth graders classify triangles. In this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Students build a castle to Ravi's design using the cubes. Students then make an original model of a solid object from diagrams which show views from the top, front, side and back. Students describe the reflection of rotational symmetry...

Students examine the concept of protein structure. They read an article, construct a three-dimensional model of an insulin protein, take a quiz, conduct Internet research, and answer discussion questions.

Pupils explore the midsegment of a triangle in the geometry lesson. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The...

Students investigate planning an activity and getting it done on time. For this algebra lesson, students define vocabulary words related quadratic equations, including the vertex and intervals. They figure a good way to color graphs...

Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...

Examine repeating and intricate patterns with a study of M.C. Escher and a related art activity. Pupils view and discuss the artwork before creating their own tessellating patterns. Step-by-step instructions for creating a template are...

It is cowabunga time! Pupils read an article about the NASA LISA mission on gravitational waves and conduct additional research on them. The class participates in a science bowl type competition about gravitational waves. Panels of four...

Scientists have been studying exothermic reactions before they were cool. The lesson plan begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed...
