So, this week we decided to take a little break from geometry, and move towards some division. I wanted to see what they knew; I wanted to see where to start my division process.
For a few, they didn't know the division symbol: ÷. For others, they didn't look at it like division, but splitting into groups. Some didn't understand the equal groups, while others went straight to multiplication, they worked backwards.
We read the book "The Doorbell Rang" by Pat Hutchins
Summary from GOOD READS:
Ma has made a dozen delicious cookies. It should be plenty for her two children. But then the doorbell rings--and rings and rings. Each ring of the doorbell brings more friends to share the delicious cookies Ma has made. "Refreshing, enjoyable and unpredictable."
Before modeling, before any discussion, the students were sent off on their own division inquiry. They were asked to represent 24 cookies in as many ways as they can. They could share the cookies with many friends, but everyone needs to get an equal amount of cookies.
Here is a little video that displays what they did, and some of the discussions we had. Students were prompted to see if they could share with 5 or 7 friends,it made for some good points to discuss. Thanks again to iMovie for letting me have fun in displaying what these students are capable of, ENJOY!
Jackson and Heather then worked with the iPad, and played with EduCreations. They were taking pictures and making annotations. Now, I think they rehearsed a bit. Although, we did miss some of their thinking, they showed a couple results and show how splitting 24 cookies into 7 groups wouldn't work. They ran out of time to complete their thought, but this will be in part of this weeks discussion. We are starting to focus on "Math Talk" so we might be able to get more out of this, only time will tell; enjoy!
In the end, we shared some of our responses, and some of the strategies we used. We then talked about the connection between multiplication and division. Overall, a successful lesson!
FOR MY CLASSROOM PARENTS -- Just a little note; by the end of grade 3, our students should know up to 49 ÷ 7. While we are learning many of the approaches and strategies for division, it is important to continue practicing with your children, to this comes quickly to them!
