Summer SAVY 2018: Session 1, Day 3 – Secrets of the Moli Stone (Rising 2nd)
As mathematicians, the students spent significant part of their day learning how to regroup. This was a somewhat challenging task for the students since this was the first time many of them have been exposed to this new mathematical concept. They were excited to learn that they will see this concept again in their regular second grade classroom during the upcoming school year. They will be little experts in their classrooms.
Another highlight of their day came when they were taken to the Land of the Treble where everything is made of three parts. For example, instead of using the base-ten system, the people in the Land of the Treble use a base-three system. The people have three arms, three legs, three eyes, toes, and three noses. They were allowed to illustrate this unique land through their own illustrations. Tomorrow they will explore the base-three system used in the Land of the Treble by comparing it to the base-ten system used in our culture. They are getting closer and closer to having the skills necessary to figure out the codes written on the Moli Stone that they found on day one.
Use regrouping to answer the following word problems.
- Mom wants to buy a Moli Stone that costs $92. Mom currently has $49. How much more money does she need to buy the stone?
- Jack drove 213 miles with his dad. Dan drove 69 miles with his dad. How many more miles did Jack drive?
