### Lesson Objective

Students will understand what a "denominator" means.

### Lesson Plan

Do Now

Give each student an index card for the Do Now

• Tell students to fold their index cards into equal parts.

Opening

• Discuss the Do Now by asking how many equal parts did you fold your paper into
• State today's objective.

Direct Instruction

• Get several sheets of colored construction paper and do the following demonstration for your students.
• Take one color and leave it whole.
• Tape it to the chalkboard and write the number 1 on it.
• Take the next color, carefully fold it in two pieces and cut them apart. Ask the students how many pieces you now have. Allow for student to respond 2.
• Hold up one of them and explain that there are actually two pieces, but you are holding up only 1 piece.
• Write1/2 on one piece of paper and tape it to the chalkboard.
• Now get a third sheet of paper and fold and cut it into four pieces.
• Ask the students how many pieces you now have. Allow student to respond 4
• Hold up one of them and explain that there are actually four pieces, but you are holding up only 1 piece.
• Write 1/4 on the paper and tape it to the chalkboard.
• Continue to do this, making 8 pieces and then 16. When one each of all of the papers is on the chalkboard, ask students if they can see a pattern.

Guided Practice

• Question students to help them see that each time there is only one piece--hence the number on the top of the fraction is the same each time--and that the pieces get smaller as the number gets bigger.
• Introduce the term numerator and denominator by telling students the following: that the number on the bottom--denominator--tells how many pieces there are and that the more pieces you cut something into, the smaller each piece will become.

Independent Practice

• Distribute and explain Independent Practice sheet.
• Allow time for students to complete the practice sheet.

• Closing

Tell students to fold into 10th. Then 20th. Which was smallest? Tenths or 20th?
