This Week in Math

This week we have continued to explore different types of measurement. As a whole class, we compared the capacity of different containers by scooping dry pasta. We first made an estimation, and then we measured the capacity by filling each container up with dry pasta and keeping count of how many cups it took. We then compared the containers' capacity by ordering them from least to most. The next day, we practiced measuring capacity again with water. Our mathematician found out that in order to give a fair comparison when measuring various containers or any object, it is crucial to stick with the same measuring tool/unit.



Then we compared the weights of different objects by using balances. Students took turns in their table groups. They confirmed their measurement by comparing their answers with others, and measure again for a accuracy. Next week we will continue to look at weight and then we will learn about temperature and time.
