What This Standard Means
What Students Need to Do
- Students look at two written numbers from 1 to 20 and tell which is greater or less. If the numbers match, they say they are equal.
What Mastery Looks Like
- A student names 12 as greater than 9, even though 9 is the larger single digit. They identify 17 as greater than 14 and say that 16 and 16 are equal.
Common Misconceptions
- Some students say 9 is greater than 12 because 9 is bigger than the 1 they see first. Others call 14 and 17 equal because both begin with 1.
How to Assess It
- Write these pairs on an exit ticket: 9 and 12, 14 and 17, 16 and 16. Ask students to circle the greater number in each pair or write “equal” if they match.
Lesson moves
Ways to Teach It
Partners place cards marked 8 and 12 on a floor number line, then point to the greater number.
Ask partners to explain why 12 is greater than 9 using a number line drawn on the board.
Play numeral showdown: partners each draw a card numbered 1 to 20, name the greater number, and check the number line.
Put $8 and $12 price tags on two classroom items and ask which costs more.
