Seven "ate" nine...or 7, 8, 9! 
For Parents
For Students
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".
Practice
- You can click here for your Sprint. If someone at home can time you (90 seconds), try to beat your score from side A! Don't forget to look for those helpful patterns!
- After you finish your Sprint, you can click here for your Problem Set for Lesson 4. You don't have a homework page because all of our work is from home right now!
