I’ve mentioned before that I have the same group of students this year that I had last year, so I am having to recreate the wheel quite a bit this year, as the standards overlap a bit. One of those overlaps was adding and subtracting decimals. We spent a lot of time on it last year, and I used all the decimal resources that I had already created with this group last year. We didn’t need to spend much time on it this year since it was more of a review, but I wanted to make it fun. And fun, it was! Read on to find out all the fun activities we did, including some freebies for you!
We began with estimating sums and differences of decimals, which the students actually really enjoy doing (and it also happened to be the day I was being observed by the principal). We used a foldable from 4mula Fun (love her foldable pack) that I adapted from one of her units to explain two different types of estimating decimals. On the inside, we did an example together, and on the flap, they had to come up with their own scenarios when we might use the different types of estimating in real life. They did a great job adding in that element! After we did the first type of estimating (front end estimation), I gave them each a task card that I had created for estimating sums and differences. They had to use front end estimation to find the answer.

Okay, I think that’s it! We are beginning dividing decimals next week, and I plan to have them figure out price-per-piece of candy and some nutritional information in honor of Halloween. That should also be great fun! Have a great Halloween week, and HANG IN THERE, because I know it’s going to be a long one! 🙂
