Based on Donna Bretl's wood "Bretl Blocks" puzzles, GeoFit challenges you to fit small squares, diamonds, triangles, and trapezoids into square, hexagonal, and octagonal frames. Lots of "solutions" are possible, resulting in a wide variety of interesting, surprising, and beautiful patterns.
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.
Verdict
The clearest difference is price: GeoFit at Free against Goldbach's Conjecture's $0.99. GeoFit also leads on iOS requirement (9.0 vs 12.0). Goldbach's Conjecture's advantage is update cadence (every 8 months vs every 36 months). On ads, in-app purchases and device support there is nothing between them.
