The standard
Know number names and the count sequence.
Common Core State Standards for Mathematics
What this standard means
Students need to say number names in order, starting at 1 and moving forward without skipping or repeating. They should also begin to count on from a given number, not always restart at 1.
Mastery looks like steady oral counting, matching spoken numbers to the count sequence, and noticing when a number is missing or out of order. Students often get stuck around the teen numbers, say “eleventeen,” reverse 13 and 30, or lose track when asked to start counting from a number other than 1.
Ways to teach it
- Hands-on activity: Give students number cards 1 to 20 and have them build a floor number line, then walk and count aloud.
- Discussion prompt: Ask, “What number comes next after 14, and how do you know?” while pointing to a class number chart.
- Quick assessment: Say a starting number, such as 7, and ask each child to count the next five numbers aloud.
- Real-world connection: Count daily routines aloud, such as steps to the carpet, crayons in a box, or students in line.
