“Advance your math skills”
A good practice for higher level and older learners in areas of the four operations and reading comprehension. Suitable for older children who are capable of reading on their own. Speed limit set for each level could serve as a motivational factor for users in need of an adrenaline rush, and for those who are good with their keyboarding skills.
A way to enhance language and math skills as a fun activity (built upon this app) would be to first provide your child with a math problem e.g. 8 10 and to have the child indicate whether 8 is greater or smaller than 10. After that you could have the child write out the equation in words to form a sentence.
