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: Cube6 is an app that uses two Owlet CubeTower manipulatives. This app builds on the Cube3 app by enabling students to create six-digit numbers by stacking small cubes in the columns of two CubeTowers. Cube6 has three modes. Each corresponds to a different topic in place value: Thousands, Money, and Decimals. For each topic, there are five different activities. - Explore: Students place cubes in the CubeTowers to create numbers that are shown on the tablet. - Make: Students are prompted to make a target number by placing cubes in the CubeTowers. - Build: Students solve number puzzles. For example, students might be asked to build a number between 200,000 and 300,000 using 15 cubes. - Compare: Students create a number in the CubeTowers and then compare it to a number generated by the app. - Round: Students use the CubeTowers to round a number to a specified place.
