Another activity is to estimate the number of pieces of cereal in a box. Journals are kept to record all estimates and actual numbers. Another activity involves using a stopwatch to time routine class activities. The finale is the Measurement Fair. Students are presented with ten activities spread throughout the classroom and outside.
Students move from station to station performing the estimation and measurement activities.
For capacity, students are expected to estimate and measure how many eight ounce cups of rice will fit into a jar. For length, they need to estimate and measure how many leaps it will take to go around a baseball diamond. For duration, students estimate and measure how many times they can jump in one minute. For weight, students guess which weighs more, a cup of rice or a cup of macaroni and a cup of rice or a cup of beans. This unit incorporates several different devices for learning about and practicing measurement.
