What This Standard Means
What Students Need to Do
- Students look at a group of objects and say how many they see without counting each one. They do this with unfamiliar arrangements of up to six objects and familiar arrangements of up to ten.
What Mastery Looks Like
- A student names six dots in a new arrangement after a brief look. They also recognize eight dots on a ten-frame and can explain that they saw five and three more.
Common Misconceptions
- Some students count each dot, even when they know the pattern. Others guess from the shape of a familiar pattern without noticing that a dot is missing.
How to Assess It
- Flash an unfamiliar arrangement of six dots and a ten-frame with eight dots, one at a time. Ask, “How many did you see? How did you know?”

Ways to Teach It
Have partners arrange up to six counters in new patterns, cover them, then uncover them briefly for a partner to name the amount.
Flash a ten-frame with nine dots and ask, “How did the empty space help you see nine?”
Play a flashcard game with unfamiliar dot patterns up to six and familiar ten-frame patterns up to ten, then check each answer by counting.
At snack, briefly show six grapes scattered on a plate and ask children how many they saw.
