Number value

Patterns in place value help us write and read numbers accurately.

1. Numbers are written following a certain pattern.
2. Three digits are grouped with commas.
3. Decimal place is a marker not a place.
4. There is only one units place.
5. Pattern of thousand, million...
6. Pattern of ___, ten, hundred,
1. Each number has a certain way to be said and written that must be memorized .
2. A pattern for determining how numbers are written and said orally is too complicated for most people to understand.

Diagnostic

Ask students to describe how they can use a pattern to help them say and write number words.

Formative

Quiz students over the names of the place values and their order.

Summative

Students are able to create the order of places from ones to billions and tenths to millionths.

Generative

Use place value to communicate number value. Use of place value for problem solving.

Dimension:

Communication

Numbers are communicated in a standard way.

1. Numbers are represented orally.
2. Numbers are represented in writing.
3. Number words have correct spellings.
4. Number words have a grammar.
1. There are many standard ways to write numbers.

Diagnostic

Tell a student to write a number on the board and ask another to read the numeral and another to write the numeral in words.

Formative

Give all possible combinations of numbers and have students say and write them until they could do so for any number in the world.

Summative

Make a list of ten - twenty numbers that students had difficulty with during the practice sessions and have them read and write them.

• 1 302,
• 2 005,
• 201, 006
• ...

Generative

Recognize other ways mathematics is communicated in standard ways.

Procedure for Concept Conceptualization and Generalization

Objective:

Discover patterns in a place value chart and use then to create a procedure for writing, reading, and saying numbers from millionths to millions.

Materials:

Exploration
1. Put students in pairs.
2. Pass out place value number line and have students construct the number line.
3. Challenge students to find as many patterns as they can in five minutes.
4. Put pairs of students into groups of four and ask them to consolidate their list.
Invention
1. Have students consolidate all group’s lists into one class list on a board to display for everyone to see.
2. Discuss results.
3. Be sure all patterns outlined in the supporting information are discussed.
Exploration
1. Tell students they will explore in groups, pairs.
2. Give students the number facts sheets.
3. Tell students to do two things:
1. Use the place value number line worksheet and the information on the number fact sheet to explain how all the 14 examples are read and written.
2. Create a rule that would explain how to read or write any number less than one million and greater than one millionth.
4. Put two pairs together and have them share their results for both.
Invention
1. Bring the class together, share how to say and write the numbers, and disuss each.
2. Have each group share their rule.
3. As each group shares, have other groups give them numerals to read and write to see if the rule works or not.
4. Continue until all groups share their rule.
5. Have students identify which rule(s) they will use.
6. Have students create a problem they believe will test the limits of their rule.
7. Have students exchange their problems with their original partner, use their preferred rule, write the word number, read it to each other, and determine if the rule works.
8. Ask students if patterns can help them solve real world problems.
Expansion
1. Have students create a list of nine numbers: three written in words, three in numerals, and three either way for a partner to read.
2. Have students exchange and write or say the numbers in different ways.

## Number Facts

### Historical number facts

• Ancient Greeks numbered their armies by the Myriad (ten thousand).
• In the 1500’s Italian bankers invented the word million. It was short for mille mille (thousand thousand).
• The French later invented the work billion.
• There are about a septillion atoms in a glass of water.
• The sun weighs a little less than two decillion grams.
• A really big number was named by a nine year old boy when his uncle a mathematician, asked him to think of a name for the number one, followed by 100 zeros. The name he invented was googol.
