What This Standard Means
What Students Need to Do
- Students count objects by touching or moving each item and saying one number for each. They tell how many objects are in the whole group using the final number said.
What Mastery Looks Like
- A student accurately counts an arranged collection of up to 20 items and a scattered collection of up to 10. The student matches one number to each item and states the total without recounting.
Common Misconceptions
- Students may skip objects, count one object twice, or say numbers out of order. Some recount when asked for the total because they do not connect the final count word to the quantity.
How to Assess It
- Give each student a card with 9 scattered stars and 17 dots in rows. Ask them to count each set, record each total, and explain how they know.
Lesson moves
Ways to Teach It
Place 18 counters in two rows, then have students touch each counter while counting and choose the numeral that shows the total.
Show eight scattered dots and ask: How do you know you counted every dot once?
Play Count and Cover by drawing a number card, counting that many spaces on a 20-frame, and covering the final space.
Have students count crayons, glue sticks, or snack items before passing out one item to each classmate.
