Hello boys and girls, how is everybody today?
Good.
Today, we'll be studying subtraction, so come on, let's all gather around.
Let's gather around the computer and we're going to review the basic fundamentals of
learning how to subtract.
First, we're all going to say the subtraction equations when they show on the computer.
Then we'll all say the answer together when it's shown.
Later on, we're going to take a little test just to see how well we're doing.
And a reminder before we begin, we're going to go through the subtraction tables one through
twelve over and over again.
If you need more time, you can use this pause button on your machine whenever you need more
time to answer.
So come on everybody, let's begin.
