Florida B.E.S.T. Standards for Mathematics

Teacher's field guide

What Students Need to Do: Students read a numeral from 0 through 20 and make a group with that exact number of objects. They count each object once and stop when they reach the target.
What Mastery Looks Like: A student reads a numeral and builds a matching set without help. The student touches or moves each object once, stops at the target number, and makes an empty set for zero.
Common Misconceptions: Students may skip objects, count one object twice, or stop at the wrong number. They may also think zero means making a small group instead of an empty set.
How to Assess It: Show the numeral 14 and ask the student to place exactly 14 counters on a mat. Repeat with 0 to check understanding of an empty set.

Lesson moves

Give students numeral cards and buttons, then have them build each set in a ten-frame or counting mat.
Ask, “How do you know your set matches the numeral?” Have students explain how they counted and where they stopped.
Play Grab and Check: students draw a numeral card, count out cubes, and earn a point if a partner confirms the set.
Set up a pretend snack station where students read order cards and place the matching number of crackers on each plate.
