Properties of Logarithms
Students explore the concept of logarithms. In this logarithms lesson, students discuss the logarithm properties. Students use linear functions as a basis to develop the logarithm properites by substituting log b and log a...
Curated OER
Inequality and Simple Interest Review
Students review how to solve and graph an inequality. They also review how to find simple interest from a given problem set. The teacher performs informal assessment through observation of students.
Curated OER
The Circumference and Diameter of a Circle
Ninth graders investigate the finding of the diameter of a circle in order to extend the practice towards finding the circumference. They differentiate between the distance measured across a circle from that of around the perimeter.
Curated OER
Mean, Median, and Mode
Eighth graders practice using the LIST key on graphing calculators using the proper syntax. They work with the functions of mean, median, and mode in a teacher led lesson and then with a partner on a second data set. They follow...
