1 What happens to the fractions as the frog moves forward? The fractions get closer to 1 and they get larger. 0
One student selects Bag A, B, C. D, etc. Turn the bag around and it will be labeled “Halves”, “Thirds”, “Fourths”…etc. Discuss where to position the clips on the rope. Students draw a fraction card from the selected bag. One at a time they will “HOP” down the side of the rope to where their number should be located. Stand by your number but step out of the way, and the next one hops. Once everyone has hopped to their spot, the teacher will call students’ names and they will compare their location on the number line, using words like greater than, less than, equal to. The teacher or a student should write the statement on the board using symbols..., =. Extend this by asking questions such as “how much more”, “what is the distance”, or “what is the difference”?
