Our curriculum has us teaching mostly routines and procedures the first 10 days of the year which is of course necessary, but I want to insert content as well....my question is, what do you all do for math for the beginning of the year?

When I used to teach second grade, I always started with simple math fact games. Later on, I would make up variations of those original games throughout the year.

We just start with the program. It's first module is more review ish and includes a cut and paste sorting activity. There are 8 units and I only got through 7 and a half this year. That said, it was a brand new program.

I like to teach/review graphing. We use all kinds of get to know you activities that are graphed. (Birthdays, how we get home, eye color, siblings, pets etc)

Addition/subtraction facts, calendar (date, weather, thermometer), graphing/glyphs, place value and number concepts, tangrams and geoshapes, patterning, attribute blocks....more hands on activities and group work to establish routines and co-operative learning.

I use the first 2 weeks to get the class set up with math workshop and daily math routines. I like to get kids use to the flow of the math block- a number talk, a mini lesson, private and/or partner work time, and share. So, what I have to do is:

- Teach number talk routines. I always start with quick looks on dot cards, ten frames, and/or rekenreks.
- Teach math notebook routines. We have kids paste number stories into blank composition notebooks. Review how they learned to show their work in 1st grade.
- Pick partner activities and 1st grade math games that kids played last year to model proper partner behavior.
- Have kids explore manipulatives that we'll use a lot in 2nd grade like base 10 blocks, place value disks, rekenreks, unified cubes, geoboards, etc.

Our curriculum's first 2 units are REALLY basic 1st grade review. We touch upon the content in our number talks and math notebook problems, but our focus is really on routines and setting a tone that math this year will be collaborative, open-ended, hands-on, challenging, and fun!

Starts the year off with adding & subtracting within 20, specifically using strategies focused on the making or breaking (composing or decomposing) of a ten.

I'm guessing you don't use Eureka, but I've found it's a great review/formative of first grade and really sets the foundation for the majority of second grade math content.

I actually start with place value. I have found over the past 5-6 years that if students do not have a solid understanding of place value, they don't do well with math facts, adding money, telling time, adding multiple digit numbers etc. I frontload my students with place value instruction and wow, does it pay off later on. It really helps them to understand numbers.

I start Math at the beginning of the year with an assessment to get baseline data. They like the two minute timed CBMs. I need at least three of those for baseline. They can be done whole class. Then another assessment I give covers the whole 2nd grade but not too long of a test. I tell them it lets me know if they already know some 2nd grade math.
I usually like to start teaching with a focus on Geometry because it is fun for the students and I can combine some art with it. It looks nice for decorating the room for Open House as well.
