Geometry
Unit 12
ESSENTIAL UNDERSTANDING:
Two measurement systems ( US customary & metric) are currently used in the United States
Relationship between units vary depending on the measurement system.
Conversions in the US customary system vary depending upon what is being measured
Conversions in the metric system are based on powers of ten.
When converting from a larger unit to a small unit, there will be more iterations of the smaller unit.
When converting from a smaller unit to a larger unit, there will be less iterations of the larger unit.
Measurements can be converted to solve multi-step real-world problems.
Picture graphs, bar graphs, & line plots are used to display data
The key of a picture graph tells how many items each picture or symbol represents.
The scale of a bar graph varies depending on the data set.
The scale of a line plot can be whole numbers, halves, quarters, eights, sixteenths, tenths or hundredths.
Symbols used in picture graphs & line plots should be consistently spaced & sized.
Information presented in a graph can be used to solve problems using metric or US customary measurements
Volume is an attribute of a three-dimensional solid figures that is measured in cubic units.
Volume can be measure (or determined) by finding the total number of cubic units required to fill the space without gaps or overlaps.
The process of finding volume shifts from building with cubes & counting to the multiplication of side lengths.
The area of a base of a rectangular prism is found by multiplying the length by width (b = l x w)
In a right rectangular prism, any two parallel faces can be the Bases.
The volume of a rectangular prism can be found by multiplying the length by width by height (l x w x h) or by multiplying the area of the base by height (b x h)
A figure composed of rectangular prisms may be decomposed into two non overlapping rectangular prisms whose volumes may be added to find the volume of the figure.
