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...

As learners build the "girders" of conversation by staying consistent on a particular topic, they avoid the "wrecking ball" of an off-topic comment. To help students develop this important conversation skill, this resource provides...

Learners practice remaining on topic during a conversation using printouts of chains as visual models for their work. Chains are placed in sequence while students stay on a shared topic of conversation, and a broken chain is used as...
