Students discover how to recognize tangents and how to use their properties. They investigate and use the properties of angles, arcs, chords, tangents, and secants. Students use two tangents and the properties of similar triangles to...

Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...

Young scholars examine tension and compression by manipulating objects that are strong in each but not in both. Students apply their observations to the construction of a model of a beam bridge, suspension bridge, and inverted triangle...

Pupils make a tree trunk and branches using brown construction paper. They make thumbprint turkeys using a choice of ink color. Students make the eyes from wiggle eyes and of black ink. They make the beak out of any color foamie triangle.

Students create watermelon slices using red construction paper, paints, and watermelon rinds in this excellent elementary lesson for the end of the school year. The class is also able to enjoy eating watermelon slices during the activity.

Students practice making sampler quilts out of various fabrics. As a class, they watch a demonstration by their teacher discussing the different techniques. They make their own and share them with the class asking for constructive...

First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.

Students get to a station where they place a card inside the envelope that is stapled to construction paper. When you want students to move to a different station, hand them a different index card.

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Students use translations, rotations, and reflections to create tessellations. They explore and construct several different types of tessellations including pure/semi-pure and non-regular polygon and "Escher-like" tessellations .

Students construct a pathfinder that could land an egg safely. In this physics activity, students explain the factors affecting the dynamics of falling objects. They evaluate their pathfinder design.

Students explore the relationship between flat and three-dimensional shapes. They identify the names of 3-D shapes and construct cubes from squares.

Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.

Students use magazines and other food pictures to arrange healthy meals onto construction paper.

Eighth graders discover how the change in the dimensions of a shape cause a change in the overall area of the shape, but the perimeter stay the same. They, in groups, go out to the playground and construct large areas using stakes and rope.

Students, in groups, identify examples of shapes around the school site. They take digital pictures of these shapes and use them to construct a class book.

Students construct the tangram pieces from a square paper by following directions to fold and cut. They make observations on the pieces formed and compare how they are related to each other. They explore patterns and shapes with the...

Students investigate the concept of the Food Pyramid. They use a game as a tool of discovery in order to classify different types of food in the pyramid. Upon completion of the game the students construct their own models of it.

Fifth graders investigate the type and use of lanterns in Chinese history, their cultural significance and their role in today's society. They watch a lantern maker and describe the process. Students compare and discuss a range of...

Young scholars compile a portfolio of work from a unit on Maine's natural resources and economy. They choose four of their best assignments from the unit then synthesize the ideas in each to write an essay or construct a visual history...

Students explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

In this college level algebra learning exercise, students examine patterns, formulas that describe the pattern and determine the sum of an infinite pattern.  The one page learning exercise contains five questions.  Answers...

Students investigate the mathematical concepts related to the study of The Pythagorean Theorem. They graph and review how to use a line segment to construct a triangle. Then using the theorem students calculate the length of the hypotenuse.

Students 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...
