 # Description

Understanding place value requires practicing its principles in many different ways. In this lesson, students will play games to practice reading, writing, and comparing numbers using base-ten numerals, number names, and expanded form.

# Objectives

• Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form.
• Compare multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
• Read and write decimals to thousandths using base-ten numerals, number names, and expanded form, e.g., 347.392 = 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).
• Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
