About this app

The codes in this application are based on ones and twos. The children will see a number sequence which they will have to convert into a pattern. By solving the pattern, the children will gain insight into numbers, understand their meaning and they will learn what a pattern is. The app also contains various puzzles and assignments, which makes the app perfectly suitable to play in between the lessons at school. This app contains: - 30 mini codes - 3 large puzzles - 3 types of games : mini codes, puzzles and a question mark puzzle You can find more information about my applications on my website. Kind regards, Dennis van Duin
