Learning and Studying Can be FUN!
Create Flash cards and/or index cards for information they need to learn. Punch a hole in and add them to a metal ring. Carry and use while in car or anywhere they may have free time. Check the internet, there are apps out on that will help create flashcards.
Explain how Math is used in their lives. Have them make lists, give them money and have them pay for items at the cashier counter.
Read and review their lists everyday! Make it a game. Let them know that you had homework to do when you were young. :)
Explore the suggested websites together! Have fun!
