Unit 5: Geometry and Measurement (25 days)
Part I:
Brief review of triangles, line and angles
Classify two-dimensional figures by attributes and properties
Organize figures into a hierarchy of sets and subsets using graphic organizers based on attributes and properties
Identify cubes and rectangular prisms as 3-D shapes related to volume
Use concrete objects and pictorial models to develop and understand the formula for volume(n cubic units)
Part II:
Solve problems to calculate conversions within a measurement system
Revisit: Perimeter (Bridge the 4th grade formula to the 5th grade formula), Area, Volume w/Formulas (finding the unknown) The formula is an unassessed TEK
Reinforcement of all facts through 12 x 12
TEKS: 5.5A 5.6A 5.6B 5.4G 5.4H 5.7A
Unit 5
Why do we compare, contrast, and classify objects?
How do geometric relationships help to solve problems and/or make sense of our physical environment?
How can spatial relationships be described?
Unit 5
