New York State Next Generation Mathematics Learning Standards

Teacher's field guide

What Students Need to Do: Students say the number sequence through 100 without relying on a written chart. They also name the decade numbers in order, from 10 through 100.
What Mastery Looks Like: A student can begin at 1 and keep the sequence going through 100 with no skipped or repeated numbers. The student can also say 10, 20, 30, and continue accurately to 100.
Common Misconceptions: Some students reverse teen numbers or skip a number when the decade changes, such as moving from 29 to 40. When counting by tens, they may insert ones or confuse 60 and 70.
How to Assess It: Ask the student to count aloud to 100, then start again at 10 and name only the decade numbers. Note any skips, repeats, or decade changes that cause hesitation.

Lesson moves

Build a floor path with number cards, leaving several spaces blank for students to fill as the class counts aloud.
Ask, "What changes when we move from 39 to 40, and what pattern do you hear in the next numbers?"
Play a circle game where each child says the next number, then repeat the game using only decade numbers.
Count 100 classroom objects into ten cups, placing ten objects in each cup and naming each running total.
