Seventh graders study ratios, scale and distances according to a three dimensional model.  In this exploratory lesson students create their own constellation and prepare an oral presentation that describes their model. 

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Sixth graders convert customary linear measurements. They explore using ratios to convert from inches to feet, ounces to pounds, etc. In groups, 6th graders complete conversions. They explain to the class how to solve their problems.

Twelfth graders examine the physics of rocket flight. They build and launch model rockets to measure their performances.

Students explore measurements by completing worksheets in class. For this geometry lesson, students identify the basic measurement units in both the English and metric systems. Students analyze 2 and 3 dimensional objects and identify...

High schoolers create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students investigate the properties of two and three dimensional objects. In this geometry lesson, students differentiate polygons based on similarity and congruence. They make observation and interpret the data.

Students model three-dimensional objects using cubes. In this geometry lesson, students calculate the volume and derived the amount mathematically. They use different objects to create two and three-dimensional objects.

Learners identify the pattern in a problem. In this geometry instructional activity, students make predictions, collect and analyze data. They apply the idea of scales and measurements to the real world.

Students calculate the lines of symmetry using polygons. In this geometry activity, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.

Students investigate special segments in triangles. In this geometry instructional activity, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.

Students differentiate between parallel and perpendicular lines. In this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.

Pupils solve linear equations using graphs. In this algebra lesson, students depict real life situation using lines and functions. They identify the slope, data and predict graphing behavior.

Students investigate symmetry in the real world. In this geometry lesson, students inter-relate math and technology. They create and name a variety of polygons.
