## Compare And Order Non-rational numbers

Wilma L. Collins

GPISD

### TEKS Objective 6.1A

• (1)  Number, operation, and quantitative reasoning. The student represents and uses rational numbers in a variety of equivalent forms. The student is expected to:

• (A)  compare and order non-negative rational numbers;

### Purpose

• The purpose of the lesson is to determine students understanding of number concepts

• Students will successfully read, compare, and order whole numbers and decimals.

### Paper Plate Presentation

Materials

• 2 sets of Paper Plate Presentation plates

• Transparencies or list of Paper Plate Presentation numbers

### Directions

• two teams with a set of plates.

• Each team member should have a plate.

• This is a silent game, if a student talks during play, a point will be deducted from the team’s score.

• Show the first problem.

### Directions Continue

• Once the problem is uncovered, the team members with the appropriate plates should arrange themselves at the front of the class to represent the number/problem displayed from the transparency.

• The students have 30 seconds to form the number/problem at the front of the class. After 30 seconds, each team is given a point for a correct answer.

7. An additional point is given to the first team to “present” the correct answer.

8. Play continues until all of the numbers/problems have been displayed.

9. The winning team is the one with the most points at the end of the game.

### Presentation Numbers

1. five thousand, two and one tenth

2. Seven hundred twenty-three and eight hundredths

3. Eighty and four thousandths

4. Nine thousandths

5. One and fifty-three hundredths

6. Two hundred one thousand, thirty-six

### Presentation numbers continue

7. Fifteen and two tenths.

8. One hundred twenty thousand, three hundred seven and four tenths.

9. Four hundred twenty-five thousand, three hundred seventeen and eight thousandths.

10.one hundred forty-six thousand, three hundred ninety-seven

### Guided Practice………..

Place the following numbers in order from greatest to least.

0.75, 0.615, 0.58, 0.195

1. Line-up numbers and add zero(s)

0.750

0.615

0.580

0.195

2. Look at number in the tenths place, all the numbers are different, so arrange that number in order from greatest to least.

.615 ,.195, .580, .750, than reorder all

.750

.615

.580

.195

### Conclusion

• Start at the far left place value of the numbers, adding zero(s) as place holders when the numbers don’t have the same number of place values.

• Compare the digit of each place value where the digits are different.

• The way those digits compare is the way the whole numbers compare.

• Use > (greater than), < (less than), or = (equal to) when comparing numbers.
