This lesson will provide real world examples that involve setting up and solving for an exponential growth problem.
The task provides a reasonably straight-forward introduction to interpreting the parameters of an exponential function in terms of a modeling context.
In this Khan Academy activity, students will determine which model, exponential or linear, fits a word problem.
In this Khan Academy activity, students will find the next term in an arithmetic sequence.
In this Khan Academy activity, students will find the next term in a geometric sequence.
In this Khan Academy activity, students will find the next term in a geometric sequence.
This is a very open-ended task designed for students to develop some of the basic ideas surrounding exponential growth. While implementations will vary, the core idea is that each fold of the piece of paper doubles the height of the stack. Combined with an estimate of the original thickness of the paper and the distance to the moon, this is enough information to deduce the minimum number of folds to get there.
In this Khan Academy activity, students will factor monomials.
Lesson on factoring quadratic equations using the "X-box" method.
Students will be shown step by step how to set up a quadratic equation in order to factor it.
