Are you always looking for extra problem resources to incorporate in your classes?  A set of problems for a full AP Calculus course may be all you need! Each unit has a full set of questions and a sample test.

Use several skills to solve word problems leading to systems of equations. Scholars define variables and write equations to model situations described within word problems. Pupils solve the resulting system of linear equations using...

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

The representation of a relationship really depends. The difference between dependent and independent variables is the focus of a short video that also includes examples of determining the types of variables. The presenter makes the...

Some learners are independent, while others are dependent on lessons like these! An instructional video  discusses the difference between independent and dependent events when calculating a probability. The lesson begins with...

Sal takes your class’ newfound (or growing) knowledge of graphs of lines to the next level. He presents a few word problems in which mathematicians need to understand how to use linear function graphs.

Getting a meal, side dish, drink, and dessert can be delicious—but it can be expensive too! Practice addition and subtraction with money in a lesson that focuses on a sample menu, complete with task cards and word problems.

Use dependency to find a birthday. Learners use an interactive to keep track of excluded potential dates of a birthday using information provided to two people about a third's birthday. Scholars then use the dependency between the dates...

Young scholars apply their knowledge of math by rewriting word problems using equations. For this word problem lesson, students build upon previous knowledge as they set up the correct steps to solve word problems. This lesson is full of...
