The use of estimation is vital in determining the reasonableness of measurement. Demonstrate the structure and use of systems of measurement. Demonstrate an understanding of length, area, volume, and the corresponding units, square units, and cubic units of measure. Examine areas that can be enclosed using 24 feet of fencing and figuring out the maximum area. Calculate the volume and surface areas of cones and pyramids.
Relationships are central to mathematical understanding.
A study of patterns often reveals regularity, indicating the presence of a mathematical relationship. Studying relationships allows students to make generalizations and predictions about phenomena and occurrences. Describe and represent relationships with tables, graphs, and equations. Analyze relationships to explain how a change in one quantity can result in a change in another. Use patterns and multiple representations to solve problems.
