A few years ago, I implemented, "Say NO to Oreos". WHAT????? Who could say NO to oreos? We do this when we learn about scale factor. The NO stands for New divided by Original. We start this saying at the beginning of the year, and we use it all year. In the past, I have always brought in three types of oreos:
- double stuft
We go through a lesson in which we start with the regular oreo and dilate it through an enlargement (the two types of dilations were discussed the day before); therefore, the double stuft is created. The students measure the oreos, and we calculate the scale factor used.
We then have the regular oreo and dilate it through a reduction; therefore, the oreo mini is created. We do more measurements and get that scale factor.
The students have always responded very well to this. Since I started journaling this year, I created a journal entry, so the kids could put down what they took away from it.
I love how we were able to keep something from this activity that the kids can go back and look at. The kids loved to eat the oreos!!
I am excited to see the finished journal!
