While the four students confer with their groups and write their estimates, one student from each group weighs the object to confirm its weight. The contestants then show their estimates, and the team with the closest estimate wins a point. The student selects and uses appropriate units and procedures to measure weight and capacity. The student applies measurement concepts. Clarifying Activity Students use centimeter paper to draw different rectangles that have perimeters of 24 centimeters.
Students use the squares on the grid paper to determine the area of each rectangle drawn.
