Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

The probability is high learning will occur! A well-designed unit introduces learners to the concepts of independent, dependent, and mutually exclusive events. Using Venn diagrams, the lessons ask learners to analyze many different...

Eighth graders play a game to solve problems. In this exponents and scientific notations lesson, 8th graders play a game in small groups to move colored disks from location A to location C. Students identify recursive patterns to solve...

Corresponding parts, congruent parts, congruent corresponding parts—what does it all mean? The resource challenges pupils to identify corresponding parts for pairs of figures. It uses examples of figures that undergo rigid...

Students define Pascal's triangle and special notations used to represent nth elements. In this geometry lesson plan, students solve problems using permutations and combinations. They compare the formula for permutation to that of...

Working independently or in teams, your class practices connecting graphs, formulas and words. This lesson includes a guided discussion about distance vs. time graphs and looking at how velocity changes over time.  

Students investigate modular arithmetic and how to use it to solve real world problems. In this modular arithmetic lesson, students use computers to work on modular arithmetic after a teacher guided lesson. They complete guided practice...

Students analyze linear functions. In this algebra instructional activity, students create a linear model to relate coordinate pairs. They evaluate and solve equations.

Students note the similarities between decimals, fractions and percentages. They practice converting numbers between these types. They participate in an activity as well.

Young scholars recognize methods used to define the mole. After converting various quantities to the mole, students provide a context for understanding the usefulness of scientific notation and the mole.
