One student scoops and fills the jar as the other student records with tally marks the number of scoops. Students compare their estimate with their actual measurement. Clarifying Activity Pairs of students estimate how many marbles it will take to equal the weight of one object. One student places the object in one bucket on a balance scale and places marbles in the other bucket until the scale is balanced. The other student records the number of marbles with tally marks.
Students compare their estimate with their actual measurement.
The student uses nonstandard units to describe length, weight, and capacity. This time the students estimate and measure first using small paper clips and then again using large paper clips. Students discuss the results. The student understands that time and temperature can be measured. Clarifying Activity Students determine whether the day is hot or cold by reading the class thermometer.
