This lesson offers a great review of real numbers, along with some related concepts. If your students are already familiar with real numbers, then this could be used as one complete lesson; otherwise, break it into two lessons.
Detailed answer keys are included.
The topics covered include:
-Sets, unions, and intersections
-Interval and set notation
In this product, you will find the following:
-Powerpoint Presentation (11 slides)
-Guided Notes (2 pages, a "filled in" copy is also included)
-Do Now Slips (4 slips on one page, answers included)
-Exit Ticket Slips (4 slips on one page, answers included)
-Homework Assignment (2 pages, a detailed answer key is included)
Note: Since this is intended for a precalculus course (though it could be used in Algebra 2 or as a review at the beginning of Calculus), it does acknowledge the existence of imaginary numbers. The focus is on real numbers, however--imaginary numbers will be reviewed in a separate lesson.
