Just when a young mathematician starts to feel comfortable turning word problems into linear equations, shake things up and throw inequalities in the mix. This excellent, instructive presentation takes the steps for solving an...

Here is a fun online activity that learners can use to practice imitating patterns! Along the way, they are exposed to the names of geometric shapes including rhombus, hexagon, octagon, and decagon.

Positioned inside the framework of linear and exponential functions, this lesson is more of an investigation into the effects of changing variables and constants inside an expression. The author takes familiar formulas, those for...

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

The example of two travelers meeting somewhere along the road has been a stereotypical joke about algebra as long as algebra has existed. Here in this detailed presentation, this old trope gets a careful and approachable treatment....

Introducing exponential equations means learners need to take all the rules and tricks they learned for exponents and actually apply them. This presentation comes to the rescue by touching on changing bases in exponential...

Your algebra learners will pick up some solid algebra problem solving skills and a plan of approach for some typical types of word problems in this scripted worksheet that shows how to set up and organize each type of problem,...

Two vehicles move at a constant rate of speed toward each other, but when exactly will they pass? Pupils use still images from a video to determine the rate of speed and when the two cars meet. Then, they watch the complete video to...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Student explore the value of money. In this addition and subtraction instructional activity, 2nd graders earn "money" for classroom jobs and spend it in the classroom. Students practice how to add prices and calculate change. This...

Third graders practice making change with money. In this subtraction lesson, 3rd graders watch a video about money. Students investigate what it means to earn money, spend it, and find their change.

Fourth graders explore the concept of maintaining money. In this personal finance lesson, 4th graders earn "money" for cleaning their classroom desks. Students spend the "money" in the classroom and practice making change.
