Lesson objective: Apply knowledge of place value to compose two-digit numbers.

This lesson provides an opportunity for students to apply their knowledge and understanding of place-value to a mathematical situation. Students are asked to represent two-digit numbers in multiple ways.

Key Concept students will use:

• The first digit of a two-digit number tells us how many tens there are and the second digit tells us how many ones there are.

Skills students will use:

• Understanding of the counting sequence to 120.
• Understanding that two-digit numbers are made of tens and ones.

Students engage in Mathematical Practice 2 (students make sense of the relationship between the numerals and the quantities; students will notice the pattern in the numerals as the quantities those numbers represent change) as they represent two-digit numbers in multiple ways.

Key vocabulary:

• arrow cards
• base-ten blocks
