The fourth area addressed in the Mathematics Core for kindergarten is “Measurement & Data”. I will unpack this one over this week and next since it is broader than the 2 previous areas.
Describe and compare measurable attributes.
- CCSS.Math.Content.K.MD.A.1 Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.
- CCSS.Math.Content.K.MD.A.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 example, directly compare the heights of two children and describe one child as taller/shorter.
Children explore “attributes” throughout their young lives. Attributes help children distinguish observable qualities of objects, people, ideas, etc. into smaller and more comprehensible groups.
Although this standard focuses solely on “measurable” attributes ( (i.e., length, height, and weight) I would broaden the exploration of attributes with younger children to include any observable qualities (i.e., color, shape). I believe that the value in providing opportunities for children to distinguish and define the attributes all around them will prepare them for the kindergarten skill of comparing measurable attributes. Understanding that a stuffed duck is “yellow” and “soft” relies not only on appropriate vocabulary but the ability to apply attribute qualities to the item. This is a beginning skill that will eventually lead to comparing attributes – the yellow, soft duck is bigger than the green, hard frog.
