This year when I found out that we were waiting to focus on regrouping until after Christmas I got a little worried. Would it be too late? Would we have enough time? Well, I can honestly say now that it was a good change for us. We are normally driving down Struggle Street when we start regrouping in the fall. Some of us get it, but most of us don’t. I normally leave school and immediately take a nap because I’m just too exhausted from pulling my hair out all day. This year things have been totally different. I think giving my kids a couple extra months helped them to be developmentally ready. Plus, we spent so much time on place value that the numbers just make a little more sense now. And, we hit addition strategies and mental math in a big way in the fall. All of the puzzle pieces are just slowly coming together.
We ALWAYS use this poem. It just helps give us a little jingle to remember. My kiddos glue it into their math spirals and model addition problems for reference.
After a couple of days using manipulatives and base ten blocks it was time to do a little partner practice. My students worked together to complete this regrouping flapbook.
My students love this flipchart from Promethean Planet. The different boxes spin to make a number, then they can show their work to the side. It creates large and small numbers.
The thing I’m most excited about is what we did below. After visitingRCA, I wanted to up the rigor a little bit and give my kiddos a challenge. So, I put two sets of numbers on the board. I had my students explain (without adding) which set of numbers they thought would add up to the greater sum. Hearing my students explain and use their strategies was such an eye opener. They weren’t always right, but that was okay! After talking, I lined up the numbers for an addition problem. Then, I allowed my students to change their mind or defend their first position. Amazing! We took it up a notch and did three sets of numbers. This was such a challenge, and even pushed my highest students to the next level. My students were BEGGING for more numbers!
You can see one of my students teaching the class how to solve a word problem that we worked on. For the most part she was facing the class while explaining, but I had to snap the picture of her back. We clapped and cheered for our word problem teacher!
Of course, I couldn’t visit RCA without thinking… I’ve got to incorporate chanting and movement more into my classroom. I’m not a singer, but I was a cheerleader, so I made up this little regrouping chant for my kiddos and they LOVE it! We have motions such as walking next door and shushing each other. You’ll just have to make it your own because I’m not videoing myself doing it, ha!
It’s not the norm to have professional development impact my classroom and instruction in such a powerful way. It’s so exciting to see how little things can change the entire tone of my students!
Do you know any 4th grade Math teachers? My sister and I just got finished making all kinds of ADDITION & SUBTRACTION activities for whole numbers and decimals!! #4thgrademath #fourthgrademath #mathteacher #mathskills #4thgrade bit.ly/4thAddAndSub ... See MoreSee Less
We’ve had so much fun creating 4th Grade Math Resources for my sister’s classroom!! So far we’ve got Place Value, Rounding, and 2 Sets of Stations done! Next up we will be tackling addition and subtraction!! bit.ly/4thRounding ... See MoreSee Less
