Train Four
 Use your hexagon pattern blocks to build the first four trains in the pattern shown above.
 Compute and then write down the perimeter for each of the first four trains. [Use the edge length of
a square pattern block as your unit of measure.]
 Compute the perimeter for the tenth train without building it.

Write a description that could be used to compute the perimeter of any train in the pattern.
 Find and write down as many different ways as you can to compute (and justify) the perimeter of
any train in the pattern.
 EXTENSION – Find a general expression for the perimeter of any train in a sequence of regular
polygons.


Usa los hexágonos de los bloques de patrones geométricos para hacer los primeros cuatro trenes en el
patrón que se muestra arriba.

Calcula y después escribe el perímetro de cada uno de los primeros cuatro trenes. [Usa la longitud de
la arista de un cuadrado de bloques de patrones geométricos como unidad de medición.)
 Calcula el perímetro del décimo tren pero sin hacerlo.

Escribe una descripción que pueda usarse para calcular el perímetro de cualquier tren en el patrón.

Averigua y escribe todas las maneras diferentes que puedas para calcular (y justificar) el perímetro de
cualquier tren en el patrón.

EXTENSIÓN – Encuentra una expresión general para el perímetro de cualquier tren en una
secuencia de polígonos regulares.
