What This Standard Means
What Students Need to Do
- Children describe an object's length, height, weight, width, or capacity. They use words like long, tall, heavy, wide, full, and empty.
What Mastery Looks Like
- A student calls a ribbon long, a block tower tall, and a cup full. They choose a word for the feature they can see or feel instead of calling everything big or small.
Common Misconceptions
- Children may call a pencil tall when they mean long. They may think a bigger object must be heavier. They may call a half-filled cup empty.
How to Assess It
- Set out two pencils of different lengths and two clear cups, one full and one empty. Ask, "Which pencil is longer? Which cup is empty?"

Ways to Teach It
Let pairs handle two ribbons, two sealed rice bags, and two clear cups, one full, then describe each pair.
Show a block tower and a strip of paper; ask, "Why does tall fit the tower and long fit the paper?"
Play word match with picture cards of a tall tree, narrow path, light feather, and empty cup.
At snack time, ask children to describe their cups as full, half full, or empty before and after drinking.
