Goldbach's Conjecture vs Owlet

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.

Owlet: GlowGrid is one of a series of apps that use the Owlet GlowBoard manipulative. The specific focus of GlowGrid is using the GlowBoard to understand arithmetic operations like addition and subtraction. Students turn the dials on the GlowBoard to model arithmetic operations with the colored lights. The GlowGrid app communicates in real time with the GlowBoard, so the app reflects student work with the GlowBoard. GlowGrid has five modes for five arithmetic operations: Addition, Subtraction, Multiplication, Division, and Division with Remainders. Each operation has five different activities. - Explore: Students turn the dials to model arithmetic equations on the GlowBoard. The tablet shows the students the equation that they are modeling. - Make: The app challenges students to use the operation to make a target number in different ways, i.e. Make 11 in 9 different ways. - Solve: The app challenges students to solve arithmetic problems with the GlowBoard. - Find: The app challenges students to solve missing number problems with the GlowBoard. - Create: Students can create their own problem and use the GlowBoard to demonstrate the solution.
