McREL Standards Activity


Equivalent Numbers


Purpose:As a result of this activity, students will be able to understand equivalent forms of basic percents, fractions, and decimals (e.g., ½ is equivalent to 50% is equivalent to 0.5) and when one form of a number might be more useful than another.

Student Product:game
Material & Resources:Index cards, markers
Teacher's Note:You will need to create sets of index cards with a variety of equivalent number forms on them. Put only one number form on each card (e.g., card 1: 0.5, card 2: ½, card 3: 50%). This activity reinforces equivalent number forms that have already been taught. Use only the concepts you have covered in class. You can add cards as more number forms are learned.
Activity
Group activity Have students work in groups of 2-4. Give each group a set of cards. Have the students lay out the cards facing down. Have each student, taking turns, pick two cards and turn them over looking for a match (e.g., 2/3 and 75%). If the cards are a match they get to keep the cards. The player with the most cards at the end wins. Whole-class activity Give each student 4-5 random cards. Hold up a card and ask the students to look through their cards to see if they have a match. If they do, ask them to hold up the card. Take away the matching cards. The first student out of cards wins.
