Circumscribing a Circle About a Triangle
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...
Curated OER
Exploring the Circumcenter of a Triangle
Students construct the circumcenter of a triangle. In this constructing the circumcenter of a triangle lesson, students construct a triangle using Cabri Jr. Students draw perpendicular bisectors of the sides of the triangle. Students...
Curated OER
Midpoint of a Segment
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.
Curated OER
Investigating the Slopes of Parallel and Perpendicular Lines
High schoolers investigate parallel and perpendicular lines. They use Cabri Jr. to construct and explore the relationships between the slopes of parallel and perpendicular lines. The drawing and measurement tools available with Cabri Jr....
Curated OER
Measuring Angles in a Quadrilateral
High schoolers explore quadrilaterals in this geometry lesson. They will draw a quadrilateral, measure the angles, and find the sum of the measures of the interior angles using Cabri Jr. The interactive capabilities of Cabri Jr. allow...
Curated OER
Exploring the Orthocenter of a Triangle
Young mathematicians explore the concept of triangles as they construct altitudes of triangles to find the orthocenter. Learners construct their triangles using Cabri Jr. on their graphing calculators and find that the altitudes of a...
Curated OER
Exploring the Centroid of a Triangle
Pupils examine the centroid of a triangle as they use Cabri Jr. to construct a triangle and its medians. The dynamic nature of the software allows learners to measure the lengths of the segments in the triangle and conjecture and verify...
Curated OER
Inscribing a Circle in a Triangle
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...
Curated OER
Investigating Segments in a Right 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...
Curated OER
Measuring Angles in a Triangle
High schoolers investigate the sum of the measures of the angles of a triangle. They draw a triangle and measure the interior angles. Using Cabri Jr., learners find the sum of the measures of the interior angles. The lesson provides an...
Curated OER
Mobile-ize
Second graders, using a minimum of four space figures, create a mobile. They use a "Draw" program to first plan out their figure.
Curated OER
Blindfolds
Students stand blindfolded and turn clockwise, then counterclockwise and take 3 steps forward and make a half turn clockwise and walk 3 more steps. They discuss where they ended up and how else they could end up in the same place.
Curated OER
Area Pre- Test
In this area worksheet, 6th graders take a pre-test about what they may already know pertaining to geometric area. Students respond to 10 multiple choice questions.
Curated OER
Topics in Math
For this consumer mathematics worksheet, students explore a variety of topics in mathematics including simple interest, perimeter, area, volume, translating words into symbols, percentage problems and mortgage calculations. The fourteen...
Curated OER
Corn Prints and Henri Matisse
Fourth graders observe prints and paintings as the teacher discusses various design elements (repetition, variety, texture, pattern, etc.) used by the artist Henri Matisse. They look at and discuss Indian corn and then make a print that...
Curated OER
Ancient World
Sixth graders play a powerpoint jeopardy game. This can be used as a test or as a way to review information. This is a culminating test for our unit on Ancient Worlds. The jeopardy game is based on goals in math, language arts, and...
