Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons. Lesson to be used by EDI-trained teachers only. READY TO TEACH SM EDI ® Lessons ©2013 All rights reserved. We will write multi-digit numbers using expanded form. What are we going to do? CFU Students, you already know how to identify the place value of digits in a number. Now, we will use place value to write multi-digit numbers in expanded form. Make Connection Name Learning Objective Activate Prior Knowledge Place value: The place is the position of a digit in a number. The value is the worth of the digit due to its position. A digit in any place represents 10 times as much as it does in the place to its right. Find the place value for the following digits of 321,658. 1. 3 is in the ___________________ place. The value of the 3 in 321,658 is _________. 2. 2 is in the ____________________ place. The value of the 2 in 321,658 is _________.
