Math Update!

Our first grade mathematicians studied some LARGE, TWO-DIGIT numbers this week — some of the biggest numbers that we’ve worked with so far this year!  We noticed that every 2-digit number has a place to show the tens hiding inside along with a place to show the extra ones.  We also represented these numbers using ten sticks and circles, and wrote an equation to match our work.

Since we were working with two digit numbers, we spent a lot of time counting tens and ones this week too.  We were able to do this practice using ten sticks and circles, the number path on our whiteboards, and boxes/jars of objects.  Our first graders learned to count the tens first and then “freeze” before counting up the extra ones.  Taking the time to “freeze” is an important strategy that helps our students recognize when it’s time to switch from counting by 10s to 1s.

We can tell that our first graders are really beginning to understand the place value of these larger numbers!!!
