If you need more time, please send me an email. You know my philosophy on homework, and I believe this is a worthwhile home activity.
I will send home a sheet to get your child started on XtraMath at home. This website is a good resource for practicing addition/subtraction facts. If you prefer using flash cards or doing real-world problems, that's fine too. Just please make sure you are continuing the discussion/practice of math facts at home.
