Students complete a unit about transformations and tessellations. They explore various tessellation websites, determine which shapes tessellate, complete a log about which website activities they complete, and create a tessellation...

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Students use NASA drawings to build a model satellite for a specific mission. They design a set of drawings for their satellite showing its subsystems as well.

Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.

Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....

Students investigate the rigid motions of reflection, rotation, translation, and dilation. This investigation be accomplished through classroom instruction and exploration using Geometer's Sketchpad.

Fifth graders collect temperature readings over a period of time, enter the information into a spreadsheet and choose the appropriate graph to display the results.

Students listen to the teacher read "A Dreamer's Cloak." They examine the difference between squares and circles and create their own cloak by using a paper bag and different shapes.

Seventh graders create a graph of their Christmas gifts. They develop categories, compute fractional and decimal parts for each category, identify the number of degrees to represent each fractional part, and create a circle graph to...

Third graders measure their feet and their parents' feet, record data on computer-generated graphs, and calculate and record mean, median, and mode.

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Fourth graders explore fractions. They compare different fractions using fraction bars. Students find equivalent fractions and they use fraction bars to visualize addition of fractions.

Fifth graders design their own house, while also using problem-solving skills involving perimeter and area. They exchange houses with a partner and find the perimeter and area of the window, doors, and front side of the house.

Students complete a unit of lessons on computing area and volume. They play a Jeopardy game of basic area formulas, calculate surface area of shapes, develop a Powerpoint presentation, and conduct a simulation of finding the surface area...

Ninth graders, after being given a unique scenario and a task sheet on Dead Man's Curve, calculate and explain the force needed to keep a car on a curve using a set of formulas and a geometric property of circles. They utilize and create...

Seventh graders study steam-and-leaf plots. Given specific data, they create a stem-and-leaf plot . Students identify the mean, mode, range and median. Afterward, they review vocabulary words.

Ninth graders explore solving linear inequalities. They discuss vocabulary words and symbols associated with linear inequalities. After a demonstration by the teacher, 9th graders solve and graph inequalities. Students complete a...

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Fourth graders examine and discuss the purposes and traditions of African ceremonial masks. They design and create African ceremonial masks using various materials.

Students discover three lettered postulates that prove triangles congruent.

Eighth graders explore three-dimensional objects (prisms, pyramids, cylinders and cones) to draw nets. They use the understanding of drawing nets to find the surface area of pyramids and cylinders.
