Lesson objective: Apply ability to compare three-digit numbers in solving a real-life problem.

This lesson provides an opportunity for students to apply their knowledge and understanding of comparing three-digit numbers to a real-life situation. Students are asked to figure out how many tickets each student has, given the digits and relationship between each number.

Key Concept students will use:

- Because 100 is greater than any quantity that can be represented by a two-digit number, we compare three-digit numbers by looking at the hundreds place first.

Skills students will use:

- Read and write numbers to 1000 using standard form, word form, and expanded form
- Compare two three-digit numbers based on the meaning of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.

Students engage in Mathematical Practice 7 (Look for and make use of structure) as they apply their knowledge of the value of the hundreds place to determine and compare the number of tickets each person has.
