Kindergartners compare the sizes of things — big and small, long and short, tall and short — learning the words we use to measure and describe how things compare.
Students will be able to…
An elephant is BIG. An ant is SMALL. How do we compare how big or small things are, and what words do we use?
Project this and sort each thing into big or small. Ask children: is this a BIG thing or a SMALL thing?
Tap any phase to open the teacher moves and student actions.
