A little lesson on capacity

Today, the girls were given a basic lesson on capacity.  We discussed how capacity is the measurement of what something can hold.  The girls were shown a sand bucket and had to estimate how many times it would take to be filled with the different containers: a yogurt cup, measuring cup, water glass and coffee mug.  After they estimated, they were put into groups of three and went out to the kindergarten sandbox to complete the actual measurement.  The girls discovered while filling the bucket with sand, it took many more times to fill it with a smaller container than a larger one.
