Lesson objective: Any number of objects (within 20) can be represented with a written numeral.

Students bring prior knowledge of writing numbers to represent an amount from zero to ten from Kindergarten Unit Two. This prior knowledge is extended to numbers 11-20 as students represent larger groups of objects. A conceptual challenge students may encounter is understanding that the teen numbers are represented with two digits. 

The concept is developed through work with a number path, which supports students in matching the number of objects with the numeral representation.

This work helps students deepen their understanding of number because students understand that a quantity can be represented with a numeral.

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

Key vocabulary:

  • number path
  • numeral

Special materials needed:

  • Counting objects (blocks, cubes, counters, pennies, etc.)
  • Paper or an individual white board for recording numerals
  • Number path for each child (see "Additional materials")
