Interactives for Exploring Mathematical Concepts

Professor Ian Stewart is students’ guide through Incredible Numbers, an iPad app from Touch Press. Numbers define the patterns of sunflowers. They bring pleasure through music. And they help to answer questions such as, “How many ways are there to lace my shoes?” Interactive examples—from simple equations to a working Enigma machine—put the concepts behind mathematics at students’ fingertips. The app includes 23 articles embedded with 71 interactive demonstrations and 23 interactive sections, as well as 15 mathematical puzzles that let students immerse themselves in the patterns and concepts behind each topic: Infinity, Pi, Music, Codes, Nature, Primes, Polygons, and Factorials. Cost: $4.99

Computer Science Competition

Each year the American Computer Science League (ACSL) organizes a computer science or programming competition for precollege students in five divisions—Senior, Intermediate, Junior, Classroom, and Elementary. A preliminary competition, in which individual students compete to get their school team qualified for the All-Star Contest, consists of four contests, each of which has two parts: a written section (called “shorts”) and a programming section.

Digital Playground Exploring Mathematical Thinking

Polyup is a free digital programming environment—designed for mathematics and computer science classrooms—which translates abstract mathematical concepts and exercises into physical form.

Grants for Using Music to Teach Mathematics

The Esther Mendlesohn Fund of the Mathematics Education Trust and the National Council of Teachers of Mathematics (NCTM) are sponsoring Using Music to Teach Mathematics Grants for educators who are members of NCTE and are interested in incorporating music into the elementary school classroom to help young students (preK–grade 2) learn mathematics.
