Our Math Book On-line: Forgot your book? No worries, go to the website below, log-in (I'll send home passwords a couple of weeks after school starts), click on open math book, and then you can select the topic and lesson we are working on. Also, above the lessons you can click on the "g" for a glossary to help with unknown math terms and you can click on the "e" for e-tools, these are electronic manipulatives (pictures, aids, etc.) that can help your child pratice our math skills.
The link below has common core standards and samples/practice for each one! Just find what we're doing in class and practice at home :)
