## Placing the Digit - Place Value Practice

### Description

Using a pre-made set of SMART Notes, students will have to move numbers from a note into the correct slot of the place value chart provided on the SMART Note. Once they move the digits into the correct place, they will have to use the SMART tool to write the number in written form and expanded form. Finally, they will say the number verbally to make sure they can relate all forms to the numbers.

45 - 60 Minutes

### Lesson Objectives

The learner will be able to manipulate whole numbers to the trillions place and be able to represent them in standard, written, expanded and oral forms.

### Procedure

Start the lesson by projecting the national debt clock http://www.brillig.com/debt_clock/ and letting the students study the number. Have them come up with as many things that they notice about the number. Have tables make a list and then discuss what they notice and what they KNOW about the number.

Then go over the list using the SMART tools to write on the SMART Board what they notice, highlighting, underlining, and adding text when appropriate. Once you have gone through the list, start adding more things in regards to Place Value.

Move into different ways to express the debt number (Written like a check, Spoken like a bank teller, and Standard like an ATM receipt). After much discussion and practice using all the different forms of the number, move on to guided practice using smart note.

Open a pre-made SMART note that has a place value chart (locked in position) and random digits (unlocked) at the bottom. Then, ask for volunteers to express numbers you say aloud by moving them into the correct place value place. Have other students come up and explain what numbers in certain places stand for and say them aloud (expanded and oral). Once you have the number created, the words expressed in expanded form by looking at each digit, then have students write the number at their desk using all three forms.

For independent practice, have students work on three different numbers to be expressed in Standard, Written, and Expanded Form. Call students up to the SMART Board to share the numbers they have created and the different forms.

Have students make an entry into their math journal explaining each type of number and showing examples of each.

For students who need more practice, they can go online to the listed web sites for more practice using the different forms of expressing numbers and using place value.
