Last week KB started exploring the idea of measurement.
In kindergarten the focus of measuremnet is to build mathematical language related to weight, length, and volume. Words such as: balance, heavy, light, tall, short, big, small, empty, full, more, and less are words that we are learning together and using in different areas as we explore comparisons in our play.
Last week students played the game “I am bigger!”. Using number cards each player flipped a card over, then students compared the two cards they have.
As a class we came up with examples of things that might be “heavy” or “light”. For this exercise we pretended that we were going to have to pick up the object and that would help us determine which category the object went in. We drew our ideas:
Today, we explored the idea that mathematicians measure not only the weight of things, but also the length. Using non-standard tools like links, blocks, and pencils students set out to measure things around the classroom. Not only did they measure the lenth or height of things, but they also recorded their findings in their math notebooks and later shared their findings with a friend.
In my next post I will write about how were using the idea of balance and big and small to make good decisions about what goes into our class compost and how our language around capacity helps us in the juice shop!
