Today we'll work on Lesson 4.  In this lesson there's a sprint and we're going to keep working on subtracting up to 1,000.  Today's lesson lets us practice using the arrow way but, as always, remember that's just one strategy.  Please use whatever way works best for you.  Let's take a look at today's slides.  If they go too slow, you can always click ">" and if they go too fast, you can always click "pause".
