Third Graders have been working hard in the last month to deepen their understanding of measurement; more specifically mass, volume, and length. We started by doing some work with pan balance scales to see how much mass certain classroom items have, estimating before we starting using the scales.
Later on we worked with liquid volume, estimating the amount of liquid that would fill up certain containers before pouring the water in these containers.
Last week we read the book Jim and the Beanstalk. After reading the book, students worked in partners to create their own beanstalk, later counting and measuring the beanstalk and its leaves to the nearest quarter inch. We have used our unit on measurement to introduce basic concepts about fractions, such as what 1/2, 1/3, 1/4/ and 1/8 represent and which fractional part is a bigger amount of the whole.
