Another page of links to resources and online tools.


Sam Shah’s Virtual Filing Cabinet

Trig War  (Sam Shah) Kids play “War” with cards showing trig values of special angles in degrees and radians.

Another Great Virtual Filing Cabinet for Precalc (also has Alg 1 and Alg 2)

It Really Is All About Lines (using linear equations to build quadratics, polynomials, & rational functions–includes sign test, zeros, inequalities, graphing)

Exponential & Logs & Inverse Function: Meg Craig’s Flowchart Approach to Solving Equations

Jonathan Claydon’s (Infinite Sums) List of Precalc Activities (also has Alg 2)

Envelope Curves for sinusoidal functions–very cool!

Great Activities for Learning Transformations of Sinusoids (Which one doesn’t belong, Desmos activities, reversing the question)

Sequences & Series Introduction Using a Card Sort Activity (Sam Shah)

AP Statistics

Data: World Factbook (CIA)

Resources  Lots of great activities/puzzles/worksheets for every math subject

4 Desmos Activity Builder Formative Assessment Ideas Great ideas from Bob Lochel

Vocabulary Cards  Great visuals of math vocabulary and concepts from elementary through Algebra 2 (which also covers some Precalc concepts). Especially good for those of us not using a textbook.

Research Randomizer  Generate sets of random numbers within chosen parameters. Ex: Give me 50 sets of 10 unique numbers between 1 and 100.

Interactive Notebooks: Getting Started , Helpful Tips , Notebook ChecksYear-End Evaluation

Meg Craig’s Tech Tips  See 20 day challenge link for Math Autocorrect in Word–a way to type lots of math symbols using keyboard shortcuts

Function Builder  Great interactive online function builder–guess the function, see inputs and outputs, etc.
