Subitizing Activities for Number Sense

We all know how important number sense is. It’s the foundation of every other math skill! That’s why I LOVE subitizing activities so much – they help students start to see numbers is new ways and to begin seeing the connections between numbers.

Especially in kindergarten, I like to make subitizing a part of our daily routine, no matter what level my students are at. These are some of my favorite activities to do whole group, in small groups, and as centers!

Quick Look Cards:

In my class, we do number talks every day. I choose a different set of quick look cards each day. Sometimes we just work on fluency and identifying the number shown, and sometimes we talk about how they see each number, different ways to make the number, how many more is needed to make 10, etc.

Every Friday we do a longer math talk. This is when I show my students one of the subitizing cards (as the year goes on, I make the amount of time they have to look shorter) and I have them think about the number they see. Then i’ll have students talk about the different ways they saw the number – “I saw 3 dots and 4 dots and that is 7” or “I saw 2 empty spaces on the ten frame so I knew it was 8.”

These subitizing quick look cards are included in all of my math units because I think they’re that important!

 

Subitizing Games:

Slide1

In this game, students will roll a die. You can use a number die or a dot die (I prefer number dice for this, but I didn’t have one available!). Students will roll the die and cover that space with their counter.

This game is a freebie here.

Slide2

In this game, students will draw a domino card and cover the matching number with their counter. This game is also a freebie, and I have included a 0-6 and a 0-12 version.

Subitizing Strips:

In this activity, students will match subitizing pictures to each number strip. You can focus on all numbers 1-10 or on only a few numbers at a time.

Slide3.PNG

In this activity, students will match number cards to subitizing pictures. This will require them to work with multiple numbers at a time.

You can find both of these activities here.

 I hope you enjoyed these fun subitizing activities and that you’ll consider building some of them in to your math class next year!
