Included are Rocket math flash cards. A through W are included, since X-Z is review of all facts.
There is a strip of math facts that goes along with the math facts taught in the Rocket math program.
Answers are also included, you will just need to print them back-to-back.
** If you're having problems printing 2 sided, try turning the second page upside down (the opposite way). Some printers/copiers are different.
