Count birds to tell if Dotson made a Mystery Math Mistake when representing the number of birds using a 10-frame and writing the number to tell “how many.” Create number towers and put the towers in order from 1 to 10.

Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).

Understand the relationship between numbers and quantities; connect counting to cardinality.

Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.
