We worked to determine if it would take more yard sticks or foot long rulers to measure 18 feet. We started by having a student walk the tape line (without knowing the distance), so we could estimate how many feet it would be. Then, the second graders each put down one 12 inch ruler. We discovered the distance was 18 feet. We then compared our rulers to yardsticks and had a discussion about which tool would be easier to measure with, and which tool we would need more of. We only had one yardstick, so we had to use our rulers to create portable strings to lay down to measure how many yards the distance was. During our Number Corner time, students worked on fractions and recognizing less than half, more than half, and exactly half of different shapes.
