# Calculating lengths in similar shapes

Students learn how to identify and calculate missing lengths in similar shapes using the length scale factor. As learning progresses students begin to calculate lengths in compound shapes using their similar components.
##### Differentiated Learning Objectives
• All students should be able to calculate the length scale factor for two similar shapes.
• Most students should be able to calculate missing dimensions in similar shapes using the length scale factor.
• Some students should be able to calculate missing lengths in compound shapes by considering their similar components
