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.. )
