Can you prove it? Making assumptions in geometry is commonplace. This resource requires mathematicians to prove the parallel line postulate through constructions. Learners construct parallel lines with a 180-degree rotation and then...

All data is not created equal. Scholars examine the different types of studies and learn about the importance of randomization. They explore the meaning of causation and when it can be applied to data. 

Lead your class on an exciting journey through the world of math as they review geometry facts and solve for unknown angles. They learn how to use auxiliary lines and congruent angles to correctly complete each practice problem...

Searching for a detailed lesson to assist in describing rotations while keeping the class attentive? Individuals manipulate rotations in this application-based lesson depending on each parameter. They construct models depending on the...

Learners listen to Jack and the Beanstalk and determine what they think are the most common words.  In this Jack and the Beanstalk lesson, students reread the story, count the words they chosen and graph those words. Learners graph...

Do speed cameras help reduce accidents? Scholars investigate this question using a series of spreadsheet activities. Along the way, they learn about randomness, probability, and statistical analysis.

Students identify and interpret the function, usefulness or utitlity, form, beauty or aesthetics, and meaning, context or story, of objects and how they learn new skills and make things that they learn traditionally, by observation and...

Third graders describe, represent and compare fractions using pieces of a chocolate bar.  In this fractions lesson, 3rd graders demonstrate how to read and write fractions correctly. Students then integrate technology by using...

Tenth graders investigate the theorems of ASA, AAS, AAA and ASA. In this geometry lesson plan, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two angles are formed...

Students create spreadsheets and bar graphs based on results of survey of favorite holidays.

Students evaluate word problems.  In this problem solving lesson, students are presented with word problems requiring graphing skills and students work independently to solve.

Young scholars establish classifications of shapes by various properties (angles, sides, etc.). They introduce the important properties of common shapes. Students develop an awareness of the wide variety of ways the 2-D shapes can be alike.

Students explore Cuisenaire Rods.  In this pre-algebra instructional activity, students work with a partner to generate addition problems with the sum of ten using Cuisenaire Rods. Students construct examples of the Commutative...
