End of Unit Competency

By the end of Topic 16 students will be able to summarize how perimeter can be found.

Language Functions and Features: Describe data and/or steps to solve problems using:

●​ Mathematical terms ( perimeter, area, equilateral, side, measure, triangle ) ●​ Visuals ( design, drawing, area model ) to support approach, solution, and/or extract information ●​ Comparative language ( different, the same, equal to ) to share results ( The shapes have different areas. ) ●​ Declarative statements to state conclusion ( I square could not have the same perimeter because.. )
