Maryland College and Career Ready Standards for Mathematics (2025) · KNOW NUMBER NAMES AND THE COUNT SEQUENCE.

Teacher's field guide

What Students Need to Do: Students write the numerals 0 through 20. They include 0 and write the numbers in order.
What Mastery Looks Like: A student can write 0 through 20 without a number chart. Each numeral is clear, and the digits in numbers like 12 and 20 are in the right order.
Common Misconceptions: Some students reverse digits such as 2 and 5. Others skip 0, stop at 10, or write 12 as 21.
How to Assess It: Give each student a strip with 21 empty boxes. Say, "Write the numbers from 0 to 20, one in each box."

Lesson moves

Build 0 to 20 with magnetic numeral tiles, then write each number on a strip beneath the tiles.
Ask, "How is 7 different from 17?" Have students write both and tell a partner what they notice.
Play card draw: students pick a number card, write the numeral on a whiteboard, then check their work against the card.
Set out a pretend store shelf with price tags from $0 to $20; students write three chosen prices on shopping lists.
