Number Sense with 2-Digit Numbers

So we're FINALLY into a routine....

And we're finally into a grove with our learning... and we're really getting into using our math notebooks as a resource - not just a math journal. 

One of the first things we did was glue in our hundreds chart. I had them highlight the columns, as we talked about odd and even.


... and we've been diving straight into number sense and 2-digit numbers.  I'm not even going to lie. I have missed teaching 2nd grade math. I love teaching 2nd grade math. 1st grade math was not my favorite. 2nd and 3rd grade?? They're my jam. 

So, here are some things we did with our 2-digit number sense. 

We've been working on building, expanding, and writing out numbers....


Then we moved to all the different way to express numbers....


We did how many tens and ones, drawing out the base ten blocks, the expanded form, and word form. THEN we did the hundreds chart addition and subtraction problems.... I'll do this activity again with 3-digit numbers a little differently. 




I had them write out the hundreds chart math problems in their math notebooks first, then they got to do the posters.

Here are some of the center activities they've been doing to reinforce their 2-digit skills.

We've now moved into 3-digit number sense!  These kids are really getting the hang of it!

Have I said how much I love teaching 2nd grade math?!

I love the math journals. How many notebooks/ journals do your students use?

Learning numbers is very important in the early childhood. For one, it is th fundamental learning. For second it is the chance to learn the skills for the future profession. I doubt that your little learners will need to buy college essays online at this stage, but they would surely be interested to hear about such an opportunity. I am glad that I had the chance to read your post today and now I can be a helpful mentor to my students. Thanks for the worksheets and cool activities.

A GREAT SPELL CASTER (DR. EMU) THAT HELP ME BRING BACK MY EX GIRLFRIEND.
Am so happy to testify about a great spell caster that helped me when all hope was lost for me to unite with my ex-girlfriend that I love so much. I had a girlfriend that love me so much but something terrible happen to our relationship one afternoon when her friend that was always trying to get to me was trying to force me to make love to her just because she was been jealous of her friend that i was dating and on the scene my girlfriend just walk in and she thought we had something special doing together, i tried to explain things to her that her friend always do this whenever she is not with me and i always refuse her but i never told her because i did not want the both of them to be enemies to each other but she never believed me. She broke up with me and I tried times without numbers to make her believe me but she never believed me until one day i heard about the DR. EMU and I emailed him and he replied to me so kindly and helped me get back my lovely relationship that was already gone for two months.
