Content Area: Math
Index: 4.2D Grade 3 CPI 3
Standard: 4.2 - Geometry and Measurement
Strand: D - Units of Measurement
Cumulative Progress Indicator: 3 - The student will incorporate estimation in measurement activities (e.g., estimate before measuring).
Grade: 3
Sample Activities:
· Students estimate the number of 3" x 5" cards it would take to cover their desktops, a floor tile, and the blackboard. They describe the process they used in writing, which is then read by the teacher to determine the students' progress.
· Students work through the Tiling a Floor lesson that is described in the First Four Standards of this Framework. They estimate how many of their tiles it would take to cover one sheet of paper, and compare their answers to the actual number needed.
· Students estimate the capacities of containers of a variety of shapes and sizes, paying careful attention to the equal contributions of width, length, and height to the volume. They sort a series of containers from smallest to largest and then check their arrangements by filling the smallest with uncooked rice, pouring that into the second, verifying the fact that it all fits and that more could be added, pouring all of that into the third, and so on.
· Students estimate the angle formed by the hands of the clock. They can also be challenged to find a time when the hands of the clock will make a angles of 90 degrees, 120 degrees angle, and 180 degrees.
