This lesson reviews and extends counting by 2s, 5s, and 10s using both a number line and a number grid and focusing on the patterns these numbers create. Much of the work in this lesson will be built upon in coming lessons.

Ask your child to restate the definition of a pattern. Give her the whiteboard and a dry-erase marker, and ask her to create a color pattern. Also ask if she thinks that there are patterns in numbers and, if so, what some examples of these might be.
