Students discuss what enables us to read a face: features, expressions, standards of beauty, age and gender. They discuss what enables us to read motion: repetition, sequence, changes in form and scene.

Young scholars use Venn diagrams to represent classifications of shapes and to use counting arguments to find the number of objects in a given set.

Seventh graders create a graph of their Christmas gifts. They develop categories, compute fractional and decimal parts for each category, identify the number of degrees to represent each fractional part, and create a circle graph to...

Third graders identify healthy foods in each group of the food pyramid. In this nutrition lesson, 3rd graders take notes on the food pyramid by visiting the website, www.mypyramid.gov. Students design a healthy menu for an imaginary bistro.

Students identify the measure of missing exterior angles. In this geometry lesson,students define and apply the exterior angle theorem to solve problems. They use Cabri software to create different angles and make investigations.

Students explore characteristics of shapes by making and using tangram sets. They discover how the tangram pieces are related to one another, and determine how many different combinations of the triangles, squares, and parallelograms in...

Students study about perimeter and the units used to measure perimeter using a variety of materials including their hands, feet, rulers, and computer applets. They understand such attributes as length, area, weight, volume, and size of...

Middle schoolers will explore frieze patterns. A frieze pattern is a mathematical concept to classify designs on two-dimensional surfaces, which are repetitive in one direction, based on the symmetries in the pattern. They will explore...

Students identify symmetry in road signs. In this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.

Students are introduced to the notion of surface area and volume, learn the terminology used with surface area and volume and have experimented with the surface area and volume of different prisms.

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

Young scholars explore the concept of irregular fractals. In this irregular fractals lesson plan, students discuss how to find fractal dimensions through teacher led discussion. Young scholars calculate fractal dimensions of various...

Pupils are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Students classify angles. In this angles activity, students explore the characteristics of angles, triangles, quadrilaterals and circles. They identify polygons and sing a classifying angles song. Students participate in a...

Students study triangles. In this triangle lesson plan, students compare and classify triangles while milling to music. Students will also trade triangles so they can match up with other similar triangles. Triangles are provided.

Students investigate the supposed traveling path of a meteorite. They use sound in order to triangulate the path. The results of the experiment are written on a map to display the path of the meteorite. The culminating activity is when...

Learners use pattern blocks and triangular grid paper to review shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked: "Have you ever seen a floor or a wall...

Students calculate the area of triangles using a variety of materials including computer applets.

Learners use Venn diagrams in order to classify different objects and numbers. They then use "Venn Diagram Shape sorter" applets on the computer.

Students discover that four special segments have a common intersection point. They identify the position of the intersection point in triangles. They produce conjectures about areas of the divided triangles.

Third graders in a 3rd grade math class make connections from prior instruction and mastery to solve problems in new learning situations. Using logical thinking and prior knowledge to solve current math problems is the focus of this...

In this permutations worksheet, 6th graders solve and complete 5 different types of problems. First, they write a simple conceptual art plan with no more than 3 instructions. Then, students use graph paper and a pencil to draw a plan....

Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.
