Arithmetic Quilts combines mathematics and art. Addition tables, multiplication tables, and tables based on more complex operations are displayed as colorful quilts by assigning a specific color to each positive whole number. This makes it much easier to discover and appreciate the beautiful patterns of mod arithmetic. Quilts defined by a recursive process can also be created.
Goldbach's Conjecture
Read full descriptionHide full description
Fun and Challenging! Goldbach's Conjecture introduces students to an idea that has baffled mathematicians for centuries. In 1742, a Russian mathematician named Christian Goldbach wrote a letter to Leonhard Euler in which he proposed a conjecture. The conjecture stated that all even numbers greater than two can be expressed as the sum of two primes. This app challenges the player to find two prime numbers to make a target even number. Completing the activity involves using mental math skills. Goldbach Conjecture is designed to be a quick math exercise that teachers can use to provide extra practice in problem solving and an enriching experience for their students. Special sound effects make the game fun to use and the interactive design facilitate problem solving strategies.
