Here is how I teach Area to my kindergartners--lots of hands-on exploration and discussion, of course! All of the blackline masters I use are available to download free here: Download Measurement Unit_Area In Texas, kindergartners are only expected to compare 2 flat surfaces and tell which is bigger and which is smaller. Which is either way too easy... Or way too hard! If you have one area that is longer on one side, but shorter on another, it is difficult to compare their areas based on observation alone. So using some kind of non-standard unit to actually measure the areas is a natural extension. K.10) Measurement. The student directly compares the attributes of length, area, weight/mass, capacity, and/or relative temperature. The student uses comparative language to solve problems and answer questions. The student is expected to: (B) compare the areas of two flat surfaces of two-dimensional figures (covers more, covers less, or covers the same). K.MD.1. Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object. K.MD.2. Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the difference. For...
