1. Understand the Question

justify

On the grid you cut a triangle off one end of the parallelogram and slid it to the other side. What shape did you make, and why does that prove the area is base x height?

Your job: Answer the question. Use math evidence. Explain how the evidence proves your answer.Responde la pregunta. Usa evidencia matemática. Explica cómo la evidencia demuestra tu respuesta.

2. Plan Your Math Words

Check at least two words you will use.

Base — A side of the shape you use to find the area.Base — Un lado de la figura que usas para hallar el área. Height — The straight-up distance from the base to the top.Altura — La distancia recta hacia arriba desde la base hasta la parte de arriba. Area — How much space is inside a flat shape.Área — Cuánto espacio hay dentro de una figura plana. Parallelogram — A four-sided shape with two pairs of parallel sides.Paralelogramo — Una figura de cuatro lados con dos pares de lados paralelos. Composite figure — A shape made by putting two or more simple shapes together.Figura compuesta — Una figura formada al juntar dos o más figuras simples.

Say it first: Say your idea to a partner or quietly to yourself before you write.Di tu idea a un compañero o en voz baja antes de escribir.

When I move the triangle, I get a ___.Cuando muevo el triángulo, obtengo un ___.

3. Build Your Explanation

Model the parts: This model shows the parts of an explanation. It does not answer your writing question.

Claim: We use the height because it is perpendicular to the base.

Evidence: Students connect 'height' to the perpendicular (straight-up) distance from base to top, and recognize the slanted side is longer and would overstate the area.

Reasoning: This evidence connects the definition of parallelogram to the mathematical claim.
