In this Algebra I/Algebra II worksheet, students solve radical equations.  The two page worksheet contains a combination of thirteen multiple choice and free response questions.  The answers are included. 

In this triangles activity, learners respond to 4 short answer problems. Students describe side relationships of different types of triangles. Learners find the area of a segment formed by a sector.

In this circles worksheet, students solve 10 multiple choice problems. Students answer questions about diameter and chord relationships, tangent lines to a circle, circumference, the Pi relationship, etc.

In this Algebra II/Pre-calculus worksheet, students explore radian measure of an angle and convert between degree and radian measure. The seven page worksheet contains explanation, examples, and nineteen multi-part problems. Answers are...

This instructional activity starts with geometers discussing how to find the volume of a cone and pyramid, using what they know about the volume of a cylinder or prism. Then, using the formulas, they calculate the...

In this Algebra I worksheet, students differentiate between precision and accuracy is measurement.  The four page worksheet contains thirty-five problems.  Answers are not included. 

Students learn three different types of muscles. By building a model of the arm, they learn its basic anatomy and how muscles function in relationship to bones. They perform an experiment on the relationship between muscle size and...

Students classify, flip, slide, and turn a quantity of quadrilaterals.

Fifth graders write and illustrate books to make a class library of math term books. They utilize vocabulary associated with geometry to make their books. For example, one character may be, Mr. A Cute.

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Young scholars analyze characteristics of various 2 dimensional shapes and explore their properties and use various vocabulary terms to discuss geometric relationships.

Students study geometric terms related to circles and solve the problem posed in the book.

Students explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T, and the "centripetal acceleration" of an object.

Students, in groups, determine the volume of a box large enough to hold a million dollars. They calculate the dimensions of a bill and the volume of the money.

Students list three examples of momentum found in their local environment; describe the importance of mass and velocity on momentum; and determine what is necessary to produce the greatest amount of momentum within a particular system.

Students analyze the weather patterns in Namibia. They create a graph of the yearly temperatures and use the internet to gather information. They discuss how the weather goes in cycles in the area.

Learners make spinners to investigate rotational inertia, rotational speed, angular momentum, and velocity. They make two sets of spinners that have different mass distributions and shapes. They complete a worksheet while experimenting...

Students identify polygons.  In this polygon people activity, students draw required shapes and construct a polygon person.  They identify each shape and its characteristics.  The activity may be extended by allowing...

Pupils circumscribe a circle about a triangle. They construct a triangle using Cabri Jr and then circumscribe it. They then use knowledge of perpendicular bisectors and circumcenters to locate the center of the circle and then...

Pupils investigate inscribing a circle in a triangle. They use Cabri Jr. to draw a triangle, locate the incenter, and use the distance from the incenter to a side of the triangle to inscribe a circle. The dynamic nature of the geometry...

In this blood pressure worksheet, students compare their heart rate at rest and after exercise and their blood pressure at rest and after exercise. This worksheet has 6 fill in the blank and 12 short answer questions.

For this pi worksheet, students evaluate the curve of a quarter of a circle. They analyze the length of the curve, and explain that if the area under the curve is equal to pi, the length of the curve above is also equal to pi. Students...

In this limitations of formulas worksheet, students answer four essay questions about functions. Two questions refer to the limitations of formulas. They graph one function and explain how it specifies the rule of the function.
