2. Indirect Comparison
Unit Overview
In our daily lives we come across objects having length, area, capacity, and
weight. To understand these concepts effectively, categorization, comparison,
and measurement --preliminary unit lengths such as hand lengths or steps and
standardized units such as cm and g-- must be learned. In this unit, we
practice comparing length, area, capacity, and weight. Guide students to use
indirect comparison when direct comparison is not possible.

Compare Lengths Compare Capacities
Count the rocks to compare the length of the objects. If the water from containers A and B is poured into the cups of
the same size, the container that holds more water can be found.
3 rocks 4 rocks
AB
The color pencil is longer than the glue stick.
Container A holds more water than container B.
Compare Areas Compare Weights
Count the number of to compare the areas. The weight of coke can and sprite bottle can be compared by
finding the number of yogurt bottles that is needed to equal
The area of the chocolate the weight of each beverage.
