We're wrapping up our "Farms and Fences" unit about measurement. We discussed standard units of measurement. In other words, every foot, inch, and centimeter are all the same size and we use these units to talk about things (e.g. the table is 39 inches long and 24 inches wide). Within measurement, we know that there different combinations (ways) to get to a total.
Cheers,
Ms. Liang
