  4. Not realizing that fractions and decimals describe the same point on a line

  5. These can be changed to all fractions or all decimals

  6. Change to Decimals -8.2, -8.3, -8.7, -8.6

  7. -8.2, -8.3, -8.7, -8.6 -8.6 -8.3 -8.2 -8.7 • -8.7, -8.6, -8.3, -8.2 l l l l l l l l l l l -8 -9

  8. Change to Fractions

  9. l l l l l l l l l l l -8 -9

  10. What about if we don’t change them at all?

  11. -8.7 -8.2 l l l l l l l l l l l -8 -9

  12. -8.3 -8.7 l l l l l l l l l l -9 -8

  13. -6.95 -7 -6 -6.7

  16. 10 5 2.2 0 -2.3 -5 -10

  17. In this lesson you have learned about locating rational numbers by using a number line.

  20. Make a large number line from -10 to 10. Leave a lot of room between numbers. • Write down positive and negative fractions and decimals between -10 and 10. Locate the numbers on the number line. • If working with a group, make a number line large enough to walk on. Have the group arrange themselves correctly on the number line.

  21. Take a number line and put some marks on it. Challenge your partner to come up with a decimal number for the point while you come up with a fraction. Take turns trading off who does the decimal and who does the fraction.

  22. Make at least 20 cards with either a fraction or decimal on it. Divide the cards between you and your partner. Each of you turn over a card at the same time. Whoever has has the higher card takes both cards. Play continues until one person has all the cards. • To make it harder, limit the value of the cards, i.e. all numbers must be between -5 and 5.
