Teachers Joanne C. da Luz and Justin Warren came up with a fun twist on Lab Gear multiplication. They work at the Life Learning Academy, a San Francisco Unified charter school on Treasure Island. They describe their project in a PDF entitled "Algebra and Art". The idea is to combine the idea of the area… Continue reading Algebra and Art

Worksheet Tweaks
Because of feedback from participants in my "No Limits!" workshop last summer, I tweaked some worksheets:- Graphing Square Roots- Quadratic Forms- A Different Approach to the Quadratic Formula(The latter two can be found on the Parabolas and Quadratics page.)--Henri

Those sometimes duplicate, sometimes complement the other function diagram material on the Web site.I added an "index of selected topics and tools"… Continue reading More Small Changes
