Linkfest for Friday, February 28

• A good math acceleration program from another college in same district as mine, getting students from arithmetic to the algebra needed for statistics in one semester. We are beginning to implement this program too.
• Some research on 'chunking'. Although the article doesn't make the connection, chunking helps make math easier - when the basics become automatic, your brain gets to focus on higher level tasks.
• An interesting curriculum for pre-algebra and algebra, at middle school and high school level.
• Lesson on population growth using guesses and World Bank data.
• Malke asks how spatial reasoning helps in math, and how this skill is developed. Her Math in Your Feet program is making a big difference for upper elementary students.
• A roller coaster project for calculus, from I Hope This Old Train...
• How big is a billion? from Rebecka Peterson
• Giant 4D Buckyball sculture
• Bridges of Konigsberg video, from the Plus Math blog
• In beginning algebra, I like asking students to figure out whether a big or small pizza is a better deal. Here's some data, from the Flowing Data blog.
• Rodi asks some great questions about what value others see in her math & art math circle.
