“State” – get it. (hee hee)

So, as I’ve already said, I’m a teacher of fifth grade students in a public elementary school in San Francisco, California. Which means I’m familiar with California’s previous standards for mathematics. They’re what I’ve been using to guide my teaching for many years now.

And I’ve been familiarizing myself with the new Common Core Standards for Mathematics. Some time ago, my principal asked me to go to a two-day professional development session run by our district. I learned a great deal about the Common Core Standards for Mathematics, and I have begun to share that with my colleagues at our school site.

And one of the things I learned is that states are allowed to add standards to the Common Core. (I don’t believe they’re allowed to subtract any.) And my state, California, has done so.

Now that I’m in the planning stages of writing *How to Help Your Child with Fifth Grade Mathematics*, I’ve gotten curious about what the other states have done.

So far, I haven’t seen that other states have added to the Common Core Standards for Mathematics. I’ve been using the In the States page at the Common Core State Standards Initiative website.

I looked first at New York, since it’s such a populous state. (Texas has not yet adopted the Common Core Standards.) Then, in my completely unscientific manner, I looked at Indiana, my home state. Next, I looked at Illinois and Ohio. None of those four states has added to the Common Core Standards for Mathematics.

I’ll keep checking from time to time, but feel free to leave me a comment if you know your state has added to the Common Core Standards for Mathematics. I want to include any of those additions in *How to Help Your Child with Fifth Grade Mathematics*.

This is a big and important change, where we will have the same standards at each grade level in nearly all the states. But, if there are additions, I want to include those in my book. There’s not much point in having common standards and then ignoring the few differences. I want the information and help I provide to benefit any parent in any state that has adopted the Common Core Standards for Mathematics.

The Common Core Standards have been adopted by forty-five states. Only Alaska, Minnesota, Nebraska, Texas, and Virginia have not adopted the Common Core Standards. The standards have also been adopted by the District of Columbia, and four U.S. territories: American Samoa Islands, Guam, North Mariana Islands, and U.S. Virgin Islands. Puerto Rico has not adopted the Common Core Standards. The Department of Defense Education Activity has also adopted the standards, which affects children of men and women serving in the military in Europe or the Pacific.
