•
Understand the sum of any two side lengths is greater than the third
Explore the relationships among points, lines, planes, angles, and shapes
Use TI-73 graphing calculators to explore ordered pairs and transformations.
Identifying Big Ideas from Unwrapped Standards:
1. Perimeter and circumference is a distance around a figure (units), area and surface area is the
inside space (units squared), and volume is how much a figure holds (units cubed).
2. Triangles can be classified by their sides and/or angles.
3. The angles in all triangles have a sum of 180 degrees.
4. Polygons are classified by the number of sides.
5. Similar triangles are proportional.
6. Ordered pairs are graphed on a coordinate plane.
7. A transversal line forms different types and pairs of angles.
Essential Questions from Big Ideas to Guide Instruction and Assessment:
1. Compare and contrast perimeter, circumference, area, surface area, and volume.
2. How are triangles classified?
3. What is the relationship among angles of a triangle?
4. How are polygons classified?
5. How is a missing side of similar triangles calculated?
6. How are points, lines and simple shapes graphed?
7. What relationships are formed by parallel lines cut by a transversal?
