Today's objectives
Content Objective: I can draw polygons from their vertex coordinates on the coordinate plane, and use coordinates to find side lengths and solve perimeter and area problems.
Language Objective: I can explain how I found a distance using the words vertices, coordinates, and absolute value.

Write About the Math
Where do the other two vertices go — and how do the known coordinates, the scale, and the area work together to tell you?¿A dónde van los otros dos vértices — y cómo trabajan juntas las coordenadas conocidas, la escala y el área para decírtelo?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: When two vertices share the same y-coordinate, the segment between them is horizontal, so its length comes from the DIFFERENCE in the coordinate that changes — the x-coordinates. — A strong answer explains that the SHARED coordinate tells you the direction of the side, and the DIFFERING coordinate is what you subtract. A weak answer just says 'subtract the numbers' without identifying which pair.

- The park's width is ___ feet. Using the area formula, its length is ___ feet, which is ___ units on the map — so the new vertices sit that many units below the known ones.
- My answer is ___ because ___.Mi respuesta es ___ porque ___.
