What K.MD.1 Means in Plain English
Kindergartners learn that an object has things about it you could measure. Hand a child a water bottle and ask what we could find out: how tall it is, how heavy it is, how much water fits inside. No numbers, no rulers, just the words long, heavy and full.
The second sentence of the standard matters most: one object has several attributes at once, so a pencil is both long and light. This vocabulary is what children compare with in K.MD.2, and in 1st grade they order three objects by length (1.MD.1) and measure with units (1.MD.2).
K.MD.1 I Can Statements
- I can tell what could be measured on an object.
- I can use words like long, heavy and tall.
- I can name more than one thing to measure on the same object.
K.MD.1 Worked Example
One water bottle from the classroom shelf, described three different ways, which is the whole standard in a single object.
Pick up the blue water bottle from the shelf. What could we measure about it?
- Stand it up next to the glue stick. There is a “how tall” to this bottle.tall, taller than the glue stick
- Lift it with one hand, then lift the empty one. There is a “how heavy” to it too.heavy when full, light when empty
- Look at the water inside. There is a “how much it holds” as well.holds a lot of water
- Say all three together. One bottle, three things we could measure.tall, heavy, holds a lot
Check it: Ask the class for a fourth. “How wide is it?” counts. “It is blue” does not, because blue is not something you can have more or less of.
Common Mistakes with K.MD.1
Naming a color or a shape
Asked what we could measure, the child says “it is red” or “it is round”
Try this: Ask whether the bottle could have more or less of that. More red makes no sense, but more tall does, so tall is measurable.
Big as the only word
Every object is “big” or “small”, whether it is long, heavy or full
Try this: Hold up a long light scarf and a short heavy book, and ask which is longer and which is heavier. Big is not enough.
Stopping at one attribute
“The pencil is long.” and nothing else, even when asked for more
Try this: Keep a question chain ready: how long, how heavy, how wide, how much does it hold. Every object answers at least two.

Quick Check
- Name two things you could measure about a shoe.
- Is “green” something you can measure? Why or why not?
- Mr. Lee holds up a full backpack. What three words tell about things we could measure on it?
