I have also recently switched from third grade to second grade and I know how important number sense is as the students move through elementary school.
I also noticed that my class has been a little more active this week, maybe it has something to do with a full moon AND Halloween?? I wanted to think of a fun math activity for the morning. I have a Hundreds Chart and I have lots of dice so I decided to combine the two and see what happened. It was amazing!
I grouped my students into groups - 2, 3 or 4 to a group. I had each group member choose a different color marker. One Hundreds Chart per group and two die. I have many types - 6 sided, 8 sided, 12 sided and 20 sided. My group chose a 6 and 12, and as you can see from the pictures we came up with many combinations. We eventually switched the 12 to a 20 sided die. When it is your turn you can add, subtract, multiply and divide if possible. You cross out all possible combinations. It is so much fun to see how they think and what they come up with. I have to say all groups were engaged. We haven't learned multiplication yet but I noticed that some of my students have some familiarity with it and were able to count out the correct answer using the chart. We played for about 15 minutes and it was an effective use of time. The chart isn't perfect as some combinations come up more often and others not so much but I liked it and will use it again in my classroom.
I have some pictures below and a link to my free Hundreds Chart on Teachers Pay Teachers.
Enjoy and Happy Halloween!
