Number Sense Subitizing

We have been working really hard to build number sense!  Subitizing is the biggest focus!

What is subitizing?

Subtilizing is the ability to see a small amount of objects and know how many there are without counting. Subitizing is what tells you what number you roll on a six sided dice – you must practice until counting is no longer necessary! (We still have a few that need to count and we do it every day!)

We roll a dice and try to tell the number without counting!  The students now know that they can count BUT only if needed!  

Now we are working on coloring presents since it is December!  The sheet has the dots to match and the number to help with number recognition.  Download the free game by clicking on the picture!

We also play hopscotch! Roll the dice, say the number, hop beside the number, turn around and hop back....yes, you can count backwards...if you can!


 We also are still searching the room for totals!
These small cards are hidden around the room!  We search, add dots, and find a match on a recording sheet!

We also use dot cards to discuss what we see!

You can get FREE dot cards from PreKinders to play a more/less game!

We have been talking a lot about what we see on Dot Cards!  
Questions for discussion:
How many dots did you see?

How did you know how many?
How did you know that was _____?
How did you see it?
What did you see?
Did anyone see it a different way?

It is so important to not to comment on answers!  You are trying to understand the thought process that is happening in the students' heads!  It also develops students' understanding of how to explain what they are thinking!  Other may get a few ideas too!

Give the gift of number sense and subitize!
