The Early Math Team at The AIMS Center

The members of the Early Math Team at the AIMS Center for Math and Science Education are Research Associates Jason Chamberlain, Liz Gamino, Wilma Hashimoto, and Aileen Rizo, along with myself, Senior Researcher, Richard Thiessen.  We are really excited to be working with preschool children in partnership with Fresno EOC Head Start.   This year we… Continue Reading

Cups and Downs

Cups and Downs

This week’s Puzzle Corner activity is a magic trick with a mathematical, as well as a slight-of-hand, component. I first came across this trick in one of Martin Gardner’s many books on recreational mathematics. I liked it so much that I have been stumping students, friends, and family members with it ever since. In order to make… Continue Reading

Introducing the AIMS Center for Math and Science Education

The last post in this series about AIMS—past, present, and future—ended with the statement that in the next post I would talk about a vision for AIMS that would involve translating research into practice. In a sense, that is what AIMS has been doing over the years–but in a very general way–by exploring ways to… Continue Reading

The Goalpost Puzzle

The Goalpost Puzzle

The Puzzle Corner activity this week is an adaptation of a classical matchstick puzzle from recreational mathematics. As has been noted before in this column, these puzzles date back to the nineteenth century when matches were first manufactured and began to proliferate. Most matchstick puzzles can be broken into two general categories: those that are geometric in… Continue Reading

The Infinite I

The Infinite I

This week the Puzzle Corner presents an open-ended, spatial-visualization activity that should both challenge and delight your students. The Infinite I is one of those delicious “put-together” puzzles that uses only a few pieces to form hundreds of interesting shapes. In this respect, it is similar to the popular tangram puzzle. Ironically, The Infinite I is a modification of… Continue Reading

A Touchy Situation

I am indebted to Robert Benjamin, a scientist from the Los Alamos National Laboratory, for A Touchy Situation. Bob first did this activity with his son when his son was in kindergarten. Therefore, he feels that the activity is appropriate for students at all grade levels. He also notes that the activity works best if students use… Continue Reading

The Fifteen Cent Flip

The Fifteen Cent Flip

The Puzzle Corner activity this week comes from the great puzzlist Martin Gardner. In his book Perplexing Puzzles and Tantalizing Teasers, this game appears with the title The Dime-and-Nickel Switcheroo. Six squares are shown forming a two by three rectangle. In every square but one a coin is to be placed three pennies, one dime, and one nickel. The… Continue Reading

Our AIMS for the Future

Our AIMS for the Future

In my previous post I talked about where AIMS came from, what AIMS has been doing over these past more than 30 years, and what it continues to do. In this post I want to talk a bit about the underlying understanding about how children come to know concepts of mathematics that has guided AIMS… Continue Reading
