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 puzzleYou can find more information about my applications on my website www.teacherdennis.netKind regards,Dennis van Duin
