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.
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.
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.
