Liquid measurements in mathematics textbooks tend to be a subject covered in greater detail in the second grade mathematics textbooks. So first grade teachers might want to review size differences between the liquid measuring units - do not assume they have been covered in first grade mathematics. Thanks for the activity. Jim Kelly
Hi Jim, I would not assume that level of preknowledge. How this one worked in practice was that the student teachers demoed the measurements and provided pre-measured volumes of ingredients to the first graders. The major pitfalls we encountered were very very cold hands. This version solved that problem by doing all of the mixing in a large plastic screw-top jar. We used it with older kids who did their own measurement. Rolling the jars down the hall was a great large-motor activity to break up the day.
There is a lot of scope for adapting the activity; more focus could be placed on volume and measuring. Thanks for your interest in the idea. Cheers dmccabe 01:59, 6 January 2010 (UTC)
