This place value unit has been designed as a beginning of the year 3rd grade math unit. The purpose of the unit is to give students an understanding of numbers and how they are given a value. Students will understand that all numbers are made up of digits (0-9) and the position of the digits affect the value of the number. They will also understand that we order numbers to organize in everyday situations. Students will learn to read, write, and expand numbers. They will also learn to order numbers from least to greatest and greatest to least. They will then be asked to transfer their understanding of place value by imagining they have been hired as a librarian and completing their duties through organizing and ordering library books.
