YouTube Counting Song Roundup
YouTube is such an excellent resource when it comes to songs and videos. There is an absolute wealth of options on the site especially when it comes to number and counting songs. Sometimes there are almost too many options and crawling through can be very time consuming. Lucky for you
How Will Subitizing Help My Students?
Subitizing can be one of those skills that we know our students need to have but we aren’t sure when or how to go about making this happen. I want to clear subitizing up for you and to give you some “I can implement this tomorrow” activities to use in
How I Make Meaning of the Addition Sign
In my math room there is one question, far and away, that I ask more often than any other. I’m not talking about a question or prompt such as “Could you show that to me in another way?” or “Why do you think that works?” those questions could be used
Adding and Subtracting Ten Mentally
For some first grade students, adding and subtracting ten to a given number comes naturally. They know that 23 has 2 tens and 3 ones so, naturally adding another ten gives the answer of 33! For other students, this skill isn’t so intuitive. You may have taught the skill using

Fact Fluency Through Subitizing
Last summer, along with a few other math bloggers, I did a book study on the book Teaching Student Centered Mathematics By John Van de Walle, LouAnn Lovin, Karen Karp, and Jennifer Bay-Williams. Chapter 8 revolved around developing number sense and outlined a series of important number relationships. One of
Independence in Math Class
“But they could do it at the side table 10 minutes ago… why can’t they do it now???” Sound familiar? You have a handful of students who you have been pulling aside for additional help in math. You are even stepping back and thinking C-R-A and in the small group setting
What is the CRA Math Model?
One of my favorite topics to teach is ten more and ten less with 1st graders. We start out by building a 2-digit number with base ten blocks and then add or subtract a ten stick to determine the number that is ten more or ten less. I mix in
