Measurement - Finding the length, perimeter, and area of various objects using nonstandard units of measurement. Room 14 was busy measuring various objects in their classroom to find out the length, perimeter, and area of these objects. They used measuring units such as their feet, linking cubes, iceblock sticks, whiteboard markers, and dice. They made sure all their measuring units were the same, there was no overlapping of units, and no gaps in between the units when measuring the objects.
