Grade: 3, Topic(s): place value

## Purpose

Reading and writing multi-digit whole numbers

white board and marker (for individual students)

Write a five-digit number, such as 96,284. Invite a student to read the number aloud. Repeat for other numbers. Ask questions such as, “Which *digit* is in the ten-thousands place?” or point to a digit and ask children to name 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.

Next, write a number on the board using words and ask children to write them using numerals. Finally, reverse the process occasionally by writing a number using numerals and asking children to “translate” it into words.

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

I’m going to write a five-digit number. What *digit* is in the _____ place? What *number* is in the _____ place?

*number*is in the ten-thousands place? (50,000) - What
*digit*is in the tens place? (0)

- What

*If children need more practice or are enjoying their mastery, repeat. If children are ready to move on, go to Part 2.*

I’m going to say a number in word form and I’d like you to write that number in standard form.

Examples:

- Twenty three thousand nine hundred thirty two (23,932)
- Thirteen thousand thirteen (13,013)
- Fifty two thousand seven-hundred five (52,705)
- Eleven thousand one hundred one (11,101)

- 10,456 (ten thousand four hundred fifty six)
- 19,300 (nineteen thousand three hundred)
- 28,090 (twenty eight thousand ninety)
- 41,009 (forty one thousand nine)
