Lesson objective: Understand that a written numeral can be used to represent the count of a set of objects.

Students bring prior knowledge of rote counting to 10 from K.CC.1. This prior knowledge is extended to written numerals as students connect their verbal count to a written one. A conceptual challenge students may encounter is confusing which written numerals represent which count.

The concept is developed through work with dot cards, which represent both the written numeral and a set of objects that students can count.

This work helps students deepen their understanding of number because any set of objects can be counted and represented by a written numeral.

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they connect concrete representations of numbers to written numerals.

**Key vocabulary:**

- cube
- numeral
