These division flash cards are aligned to the new Common Core Standards for third and fourth grade. Answers are included on the back in small print, so they do not show through when practicing facts. Division problems are provided for all number combinations through 144 ÷ 12 . Simply print double sided on cardstock (I use yellow), and you are good to go. Print a copy for each student in your class to send home, or use both at home and at school.
