Direct and to the point (the slope at a point that is) describes this one-page proof of the derivative of the sin(x). The definition of a derivative using a limit is the first step in this sequential, algebraic, explanation of how...

Understanding how our calculus derivative formulas were derived, connects learners to the idea that the study of mathematics is continuous and cumulative. Learners will also develop a deeper appreciation for the short cuts used to find a...

Understanding how calculus formulas were derived connects learners to the idea that the study of mathematics is continuous and cumulative. Learners will also develop a deeper appreciation for the derivative's application in...

This well organized poster shows a step-by-step algebraic proof and related graphic. Understanding how formulas were derived, connects learners to the idea that the study of mathematics is continuous and cumulative. Learners will...

Your students will impress their friends and family when they can speak the language of set theory using Zermelo-Fraenkel's axioms. This poster summarizes set theory in one page and looks impressive doing it.

You'll feel prepared and ready to begin your school week when you've considered the progression of your lessons on an hourly and day-to-day basis. 

Ensure your eighth graders get the most out of their math education with this series of Common Core checklists. Rewriting each standard as an "I can" statement, this resource helps teachers keep a record of when each standard was...

Consider a new metaphor when discussing positive thinking with your learners by having them "recycle" their negative, poison thoughts and "minting" them into positive ones using these dollar bill printables!

Teaching students to "read influentially" helps them learn how to read more strategically. This technique is derived from the teaching model that learners develop knowledge via the process of interpreting new information in light of past...
