Students will enjoy this fun, colorful story about a unit block who wants to be a ten rod. Kids will enjoy acting out the story with their classroom math manipulatives. They will understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones. They will also use a basic understanding of place value to identify three-digit numerals. Students will be chanting the "Placeville Rules": Stay in your place. Count with your crew. Always respect the number nine rule.
