Today, in Math, we used the balance scales and math tools in our class to measure the mass of various classroom objects.
To begin, I asked a student to select a classroom object for us to measure as a class. Kadyn chose a foam cylinder. After, Sadie helped us measure the mass of the cylinder using marshmallows.
We found the cylinder to have the same mass as four marshmallows. Then, I asked a student to select a different tool to measure the mass of the cylinder. Xander chose tiles. We predicted that it would take less tiles to make the scale balance.
We found that the “ten stick” was too heavy… just one was heavier than the cylinder! This lead to a discussion/review of how to pick the “right tool” for the job (something we learned during our linear measurement unit).
Finally, students were given the opportunity to explore in table groups. Here are some of their discoveries:
