Grade: 3, Topic(s): place value

## Purpose

Reading and writing multi-digit whole numbers

white board and marker (for individual students)

Write a six-digit number on the board, such as 423,504. Have a student read the number. Repeat for other numbers in the hundred thousands. Ask questions such as, “Which digit is in the thousands place?” or point to a digit and ask children for its place value. The purpose here is to have children pay close attention to the language of *digit *and *number* and to be differentiate between the two. Then say or write six-digit numbers, and ask children to write each number using words.

Part 1, reading a six-digit number, prompts children to decode the value and placement of a digit. Part 2, writing a six-digit number, asks children to translate a number said aloud into written form.
