Teacher Notes

Would your kiddos have a hard time reading the number 205,017,300? Surethey would! But why? The biggest number you ever have to read is a 3-digit number! My kiddos never believe me when I tell them that, so I haveto prove it to them.

Our numbers are divided into 3-digit groups called periods. The periods areseparated by commas. Each comma has its own name: thousand, million,billion, etc. If you can read a 3-digit number, and you know the commanames, you can read ANY number!

Start by writing a 3-digit number on the board: 205 Have the students read the number: two hundred five (remember, there

is no andwhen reading numbers)

Add three leading digits and a comma: 127,205 Tell students that the comma has a name, thousand. Cup your hands around the 127 and have students read it, point to the

comma and have them say its name (thousand), cup your hands aroundthe 205 and have them read it. Repeat several times with the samenumber--remember to cup your hands and point to the comma so theymake that connection.

Add three more leading digits and a comma: 400,127,205 Ask students if they know this comma's name (million). Have the kids read the number by chunking it up: 3-digits, comma

name, 3-digits, comma name, 3-digits

That's all there is to it! It's fun to take them on to bigger and biggernumbers. After trillion, I usually tell them to research the rest of the periodnames and come back and share with the class.

Here are some suggestions for using the materials:

Students can put the 3-digit cards inorder.

Students use the place value mats andcards to build 3-, 6-, 9-, or 12-digit

numbers and read them aloud

A pair of students can use two mats,

build numbers, and compare them.

Use the "I Can" cards in aworkstation. Three versions of each

card are included--one for 6-digitnumbers, one for 9-digit numbers, andone for 12-digit numbers

Some of the same activities from the ICan cards are included in a tieredchoice board. One way to use the

board is to have each student do eithera row or a diagonal. Notice that usingrows and diagonals, the activities aredifferentiated. Put your strugglers in

the middle row.
