Dinosaur Math Games for kids is an educational game for children that teaches basic arithmetic with the help of six adorable characters: a T-Rex and five fluffy little monsters.
The game is based on the idea that children have an intuitive understanding of numbers. They can identify and count numbers and solve simple addition and subtraction problems.
This app allows kids to practice addition and subtraction within a range of numbers from 0 to 20.
It also includes a study mode where kids can review their progress.
