Percent Increase and Decrease
This worksheet has 14 problems where students need to find the percent of change between two numbers. There are three levels: level one has 9 problems, and the math is simpler. Level 2 has 3 problems that have more difficult division, and Level 3 has two challenge problems (again, more difficult division). I've included an answer key.

Percent of Increase Decrease Fall 2013 (Editable)
Instead of lecturing my students on calculating a percent of increase or decrease (percentage increase/percentage decrease), as I used to do, I now start class with a mini-lesson (15-20 minutes in length) to go over just the main idea of what they will be learning about today. I include one or two example problems so they get the main idea, and then it's their turn.
As soon as the mini-lesson is over, I set them to task on this worksheet. I use this activity within cooperative groups, and I c

It is hard to find graphs for students to be able to identify where a function is increasing, decreasing, constant, domain, range, maximums, minimums, and function values. I have worked really hard over the years to create my own graph to use as practice or even a quiz on these topics.

I have created a wonderful quiz on the library of functions. I have used Cubic function, Absolute value function, Identity function, Square root function, Square function, and Reciprocal function. Students must match the graph, name, domain, range, increasing, decreasing for each function. This quiz is a great tool for assessing your students understanding of the characteristics for each function.

Linear vs. Exponential
Sometimes students just need to practice writing equations. Here is a worksheet that allows the students to write linear equations and exponential equations from tables. They then have to decide if the function is linear or exponential and increasing or decreasing. I created this worksheet 5 years ago and every year I hear students say, "Oh, that's the difference." It doesn't take long and makes a great worksheet for after a quiz or as a homework assignment.
