We are finding new ways to get math activities to our K-12 students and families in Austin. Today we are providing three models to families served by Jose Carrasco and the Dobie Family Resource Center in north Austin: A geometry activity set that can be used for young children learning shapes and for middle schoolers and even high school.  It

Here’s a fun one!  Inspired by a conversation with Chris Daniels of Public Math. He said roll paper around a cylinder and cut on an angle to get an ellipse and produce a sine wave.  So we did!  And you can too.  Then you can make a roller from ellipses, reflect your sine curve and roll the elliptical roller along

Ximena Garcia made a laser design for the Tower of Hanoi puzzle.  You make two of each disk and glue them together for nice chunky pieces.  We use dot stampers (for bingo sheets) to color the wood.  Works great!  The laser files are in this folder on our webpage. Tower of Hanoi is a model of exponential growth – number of
