Number Sense in Kindergarten

I have been M.I.A. the past two weeks as I have attended multiple workshops regarding the new Math Common Core standards and Number Sense.  The first week I spent exploring the new Math Common Core Standards with my grade level colleagues.  This past week I explored what Number Sense is and worked on creating activities to promote number sense.  I thought this would be the perfect time to give away my first activity!!! 
 I bet you already have all the materials you need in your classroom! Even better right?  As it is the middle of August we are on a pretty tight budget around here these days!  
For this set of activities you will need some dice and the accompanying sheets. The first activity is simply called "Roll, Count, Write." Each student will need a copy of this sheet as well as a die, or pair of dice depending on when you are using this activity.  I am planning on starting this in the Math center so I will show them how we roll the dice, (yes there is a whole lesson on this) and then how we "play" this game.    Students will simply roll the die, count the number of dots (until they start recognizing the amount of dots as numbers) and then practice writing the number of dots they rolled.  

I am planning on using this activity throughout the year in the Math center. I will run this sheet back to back on card stock and then laminate them, so they can use dry erase crayons on them.  I will be able to adjust the level of difficulty throughout the year by having them roll more than one die.  

Then next activity in this set is called "Roll, Tally, Write."  Same idea as "Roll, Count, Write" except this time you are incorporating tally mark practice as well as numeral writing.  I am going to run these back to back as well on card stock and laminate them again so they can be reused throughout the year.  
The last activity is called "Roll, Write, How Many?"  In this activity students will roll the die, figure out the number they rolled, and then represent that number with pennies. This way students learn to represent numbers another way. 
These activities address the following Common Core Standards:
K.CC.2- Count forward beginning from a given number within the known sequence.
K.CC.3- Write numbers from 0-20.  Represent a number of objects with a written numeral 0-20.
K.CC.4- Understand the relationship between numbers and quantities; connect counting to cardinality.
a: When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.
b: Understand that the last number name said tells the number of objects counted.  The number of objects is the same regardless of their arrangement or the order in which they were counted.

I have referenced the Common Core Standards that each of these activities address at the bottom of each activity.  

I would love to hear how you promote number sense in your classroom.  I would also love to hear how you are addressing the new common core standards!  Have a great weekend!

Happy Counting!
