Subtracting Two-Digits

We had our first lesson on subtracting two-digit numbers.  (Side note: The class did awesome on our two-digit addition chapter.)  I was happy with the work they did today.  As I have said before with addition, knowing basic facts by memory helps in solving more complex problems quickly and correctly.  Challenge your child to see how can solve facts faster!  This is a simple skill to work on in the car while traveling to and from places.
