Checks for Understanding (Formative/Summative Assessment)


Indirect Measure - Solve problems involving indirect measurement such as finding the height of a building by comparing its shadow with the height and shadow of a known object.

0706.4.2 Similar Triangles - Use similar triangles and proportionality to find the lengths of unknown line segments in a triangle.
0706.4.3 Scale Factor-2 - Understand that if a scale factor describes how corresponding lengths in two similar objects are related, then the square of the scale factor describes how corresponding areas are related, and the cube of the scale factor describes how corresponding volumes are related.
0706.4.4 Similar Shapes - Compare angles, side lengths, perimeters and areas of similar shapes.
0706.4.5 Ratio - Solve problems using ratio quantities: velocity (measured in units such as miles per hour), density (measured in units such as kilograms per liter), pressure (measured in units such as pounds per square foot), and population density (measured in units such as persons per square mile).

State Performance Indicators

SPI 0706.4.1 Triangles - Solve contextual problems involving similar triangles.
SPI 0706.4.2 SSS/SAS - Use SSS, SAS, and AA to determine if two triangles are similar.
SPI 0706.4.3 Factor - Apply scale factor to solve problems involving area and volume.
