Students participate in culminating activities for a winter weather unit. They discuss what they have learned about winter weather, and write a diamante poem using winter vocabulary words. Students also construct a pinwheel and explore...

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...

High schoolers explore the concept of circles as they construct a circle using a program such as Cabri Jr. Learners construct a chord and a diameter that are perpendicular, then measure the bisected chord and notice that both sides of...

Learners investigate the properties of segments formed which chords, secants, and tangents, intersect. The dynamic nature of Cabri Jr. allows students to form and verify conjectures regarding segment relationships.

High Schoolers investigate the perpendicular bisector of a line segment. They use Cabri Jr. to construct the perpendicular bisector of a segment. The dynamics capabilities of Cabri Jr. allow your learners to observe the lengths of the...

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.

Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...

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...

Pupils investigate segments in a triangle by constructing a triangle using Cabri Jr. They construct segments within the triangle that lie on the midpoints of the triangle's sides. Learners then compare the slope of base of the triangle...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

Pupils explore the midsegment of a triangle in the geometry instructional activity. 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...

Learners calculate the sides of right triangles in this trigonometric ratios lesson. They use Cabri Jr. software and TI-83 or TI-84 calculators to find the side lengths and their ratios to each other for various triangles. The provided...

In this history of Ireland worksheet, students match eleven words from a word bank with their definitions. They finish a chart comparing their diet with that of a poor person from Ireland in 1845. Students write answers to 5 essay...

Students identify the properties of polygons. For this geometry lesson, students cut out shapes try to construct polygons. Students analyze the shapes and fill out a table of characteristics.

Students define ellipses and their properties. In this calculus activity, students analyze ellipses for their shape, center, major and minor axes. They create a paper ellipse to have a visual of what an ellipse really looks like in 3D.

Students solve one step linear equations. In this algebra lesson, students manipulate their variables and numbers to answer each problem. They make sure the equations stay balanced at all times.

Second graders examine the seeds in fresh fruit. In this seeds lesson, 2nd graders view different seeds and tell how they are alike and different. Students separate the seeds into groups according to their characteristics.

Ninth graders review the information that they have already learned with regard to linear equations and graphical representations. They then assist in combining equations with a graphical element and complete various graphs with this...

Students explore the concept of prime factorization. In this prime factorization lesson, students participate in an activity where they find the prime factorization and greatest common factor of a number derived from their name. Students...

Young scholars participate in numerous activities and games. In pairs, they play card games to find relationships between a random set of playing cards. After writing samples of Dear Abby letters concerning math problems, students...

Learners practice using the FOIL acronym as a procedure for multiplying two binomial expressions. FOIL occurs by multiplying the First terms, Outside terms, Inside terms and Last terms.

In this solving equations worksheet, students solve 15 equations with variables on both sides of the equal sign. Students are encouraged to check all solutions.

Fourth graders practice mastering the ability to multiply multi-digit numbers utilizing rectangular arrays and a variety of mental math strategies. They model and illustrate meanings of multiplication and division of whole numbers and...

Ninth graders add and subtract polynomials.  In this Algebra I lesson plan, 9th graders work practice problems as they view a PowerPoint presentation of the lesson plan.  Both the horizontal and vertical methods of addition and...
