Counting on Measurement
First graders explore measurement. They measure by counting non-standard units. Students use a variety of non-standard units to predict and measure volume of various containers using rice.
Curated OER
Dino Cylinders
Students investigate the capacity of containers using small dinosaur figures as the unit of measure. They work with a number of different shaped containers to compare the capacity as they practice counting the dinosaurs. They complete an...
Curated OER
Slosh, Dribble, and Plop
Students recognize the need for a standard unit of volume. They estimate and measure to the nearest liter. Also they relate the liter to the familiar everyday containers.
