Understand measurable attributes of objects and the units, systems, and processes of measurement.

Apply appropriate techniques, tools, and formulas to determine measurements.

It provides many applications to everyday life. It can be used to help learn other mathematics. It can be related to other areas of the school

curriculum. It engages the students in active learning. Data from DCCAS indicates its an area of weakness

for our students.Discuss:

How can measurement be used to help learn other mathematics?

How do you relate measurement to other subjects?

Based on yesterday’s activities, what learning styles were addressed?

Children must measure frequently, preferably on real problems.

Children must develop estimation skills with measurement in order to develop common referents.

Children should encounter activity-oriented measurement situations by doing and experimenting rather than passively observing.

Instructional planning should emphasize the important ideas of measurement that transfer or work across measurement systems.
