Optional At-Home Activities
Practice Math Facts - roll a dice to make a 2 digit number or just write some down to practice.
Use a deck of cards to make 2 digit numbers (but take out the king, queen, jack, and joker).. You can even make a game out of it! First choose 2 cards, and then your child chooses another 2 cards. Out of your selection, make a number (example: If I have an ace and an 8... I can make 18 or 81), and your child does the same. Add and then subtract those numbers!
