Skipping, when is it OK?
We are not talking about this kind of skipping, but she is cute! 
Skipping, when is it OK? 
A customer asks:
One more question, if I may . . . (I did not see this answer in the manual or I was reading so fast I missed it!)
When doing the 1 minute or 2 minute tests, do the students have to do the problems in order? We have differing opinions on this, too! Some of us tell the students if they are stuck on one, don't spend too much time and go on to the next. Others require that they do each problem in order as written. We are just trying to be consistent throughout all grade levels 1-4. Thanks so much for your thoughts and rationale.

Dr. Don's answer:
A very good question. The answers are in the manual but it is sometimes hard to remember the information until you understand the rationale. So of course I am going to give it to you! The 1 minute daily test and the 2 minute timing are very different kinds of tests and so the rules are different.
        The 1 minute daily test is a test of mastery--to see if the students have completely mastered all the facts up through that Set. So there should be no errors and nothing skipped. Some schools insist on left to right answering so that it is clear there was no skipping. If a student even wants to skip an item on the daily test--then clearly the student does NOT know all the facts to the level and should not pass. Hopefully clear.
On the other hand ,the 2 minute timing, done once every week or two ...

I love Rocket Math and I am so happy when I can convince my teachers to use it!!!  I loved your article on grading.  The only thing I wish was different is that on the old masters, the students always had a list of the problems that were new to that page.  They knew that those were the new facts to learn.  Since we are just starting out, added those new problems onto our masters.  I really wish the masters could be changed to include that before we hit the other three operations!!!!

Dr. Don replies:
      Thank you for your feedback!  The "new" problems on each set are the four problems in the upper left by the starting rocket.  In Subtraction Set C pictured above the new facts are: 4-1, 4-3, 8-1, and 8-7. While I didn't put the answers on the page, the student can get the answers from his or her checker (who has the colored answer keys).  You can also get a list of the new facts for each operation on our Free Resources page where it says "Sequence of facts."  Does it help to know that? 

Marsha replied: Thank you for the clarification on the new problems on a page.  It was very helpful! 
Hidden gem of the week!
No time to explore our website? Here's a gem you might not have otherwise noticed.
This 2015 version of the sequence of facts for Multiplication is available on our website for free even if you don't have a subscription
It is located on our immensely valuable Free Resources and Downloads page under the heading Sequence of Facts.  You have to scroll for it.  All four basic operations are listed there.  You can open and print them from there. 
Hint/Tip Idea: Post the sequence of facts above the filing crate for the operation, so students can see what facts they'll be learning when they go to collect a new set to study.   

Teacher-made Rocket Math
Video of the week.

It turns out that many of you out there create useful videos about Rocket Math.  These are posted on our Rocket Math You Tube Channel so you can access them to use.  I am going to feature one here each week.  Send me a link to yours!

Teacher Susan Stratton did this video of how to set up Rocket Math from before the subscription site.  She created a very helpful introduction and an encouragement to undergo the process of getting Rocket Math set up. 

Thank you for your interest in Rocket Math.  I created Rocket Math so we can help your students be more successful, gain confidence and enjoy math more.  Let me know how else I can help.  Feel free to call me with any questions you have or send me an email to
