Second graders calculate mileage for a journey. In this place value and measurement lesson, 2nd graders read Johnny Appleseed, work in groups to locate his birthplace on a map, locate the other states he stopped in, and measure the...

Students investigate the art of baseball. In this sports lesson plan, students discuss their thoughts about the sport of baseball and create a baseball word list. Students use pattern blocks and drawing paper to create a...

Fifth graders practice solving problems.  In this fraction and decimal lesson, 5th graders recognize the relationship between fraction and decimals.  Students estimate problem results and write expressions to use for problem...

Students describe techniques helpful in solving spatial problems which utilize the notion that a model is a simplified version of something complicated. They utilize methods such as sketching or drawing possible solutions to a problem.

Students act as surveyors. In this George Washington lesson, students read transcriptions from Washington's surveying journal and then try surveying skills on their own.

Students explore various artists and practice creating their style of painting. In this art history lesson, students discover various artists, such as Van Gogh and Michelangelo, and painting style each utilizes. Students paint a picture...

Students participate in a "hands-on" activity, to explain that African masks were and are more than aesthetic artifacts, they are functional implements of the many cultures of the African continent.

Students practice assessing how to apply the formulas for the area of parallelograms and triangles. They recount the contributions of Pythagoras and apply the theories of the Pythagorean theorem in a group project to calculate the...

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...

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...

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...

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...

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....

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...

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...

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...

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...

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...

Bring out the inner artist with this Abraham Lincoln lesson plan. Elementary students work on a home project creating a hat similar to Abraham Lincoln's hat. They will use geometry and measurement to create the scale of the hat, then...
