Write About the Math

Why did the detective use an open circle instead of a closed circle? What values of p are possible?¿Por qué usó la detective un círculo abierto en vez de uno cerrado? ¿Qué valores de p son posibles?

Say your answer to a partner first. Then write it, using at least two of these words:

Model: Because 2:00 itself counts, I use a closed circle at 2. — Students choose a closed circle at 2 (because 'no earlier than' includes 2) and shade to the right since later times satisfy t ≥ 2.

Start

Complete the frames. Use the word bank.Completa las oraciones. Usa el banco de palabras.

  • The detective used an open circle because ___ means 12 is ___ included, so possible values are numbers ___ than 12.
  • My answer is ___ because ___.Mi respuesta es ___ porque ___.

Build

Write two connected sentences. Use because, so, or but.Escribe dos oraciones conectadas. Usa porque, entonces o pero.

  • My claim is ___.Mi afirmación es ___.
  • My evidence is ___, so ___.Mi evidencia es ___, entonces ___.

Explain
