Teaching Math With You Tube Videos: Subitizing

About 5 years ago, I started a very popular series on my blog called Teaching Math with Youtube Videos. I have posts about







Teen numbers

Area and perimeter

Addition facts

Subtraction Facts

 They are a great way to get a little movement break while still working on important math concepts. These little movement breaks have been super important as we have transitioned from summer vacation back to school 5 days a week. 

I try to keep these posts up to date and have deleted and added videos to each of them a few times a year.  They still get lots of visits each month and are a great way to have all the content from one topic in one area. I recently spent some time making updates to these posts and noticed that I don't have one dedicated to subitizing.  Since there are some fabulous subitizing videos on You Tube now, I thought I would share with you a few of my favorites!

What is Subitizing? 

Subitizing is the ability to instantly recognize quantities.  It is an important early math skill and a must master for kids in K and grade 1.  The ability to subitize can further be broken into perceptual subitizing which is the ability to instantly recognize small quantities and conceptual subitizing which is when you decompose the image into smaller parts and add what you see together in your head. 

We love using videos as a great way to practice this skill along with number talks, a few apps and our Movin' it math cards.

Start Out With Subitizing Quantities to 5

If your kiddos are new to subitizing, start with one of these!  Many of these can be done with perceptual subitizing which just a touch of conceptual subitizing required.  Work on subitizing to 5 first and move up when kids are ready!

Some have answers included (after a few seconds for students to answer first) and others are open answer (it never confirms the right answer).  We usually start with the original version and try the open answer as students are ready.  

Subitize to 10!

Lots to choose from here!  A note on pronunciation:  There seems to be 2 different ways folks pronounce subitize.  I say it [soob-itizing] but some folks say it a little different! 

Do you have a favorite subitizing song?

Are you a parent of a kiddo in grades 3-5?

After a lot of hard work behind the scenes for the past several months, I'm so excited to finally announce that I have my first published print book coming out in just a few weeks, the Complete Multiplication Workbook.  Multiplication is a must-know skill and builds the foundation for future math success.  The Complete Multiplication Workbooks is the one-stop guide for making sure kids have a strong foundation in multiplication.  I would love you to support my first print workbook!  You can pre-order your copy here!

More sneak peaks inside coming in the next few weeks!
