tenemos dos pasteles iguales. De una
pastel nos comemos medio trozo y de
la otra, nos comemos 2 cuartos de
tarta, ¿en cuál de las dos queda más
cantidad de tarta?
Quedan en ambos pasteles la misma
cantidad. Aunque la primera la
hayamos representado con un medio y
la segunda con dos cuartos, los dos
pasteles representan la misma
cantidad. Estas dos fracciones son
equivalentes.
Multiplicar denominador y
numerador por el mismo número.
Hallamos una fracción equivalente
con numerador y denominador
más grandes.
Denominador y numerador por el
mismo número (ambos deben ser
divisibles por este número). Así,
estamos hallando una fracción que
es equivalente con numerador y
denominador más pequeños.

DE QUÉ SE TRATA?
La actividad de jugar con envases de
jugos en clase sirve para representar
mejor la cantidad de una fracción y
poder tener una una idea más clara de
los problemas matemáticos que se
trabajarán
¿QUÉ SE HIZO EN CLASE?
Durante las sesiones del profesor
trabajamos con esta técnica de
representar las fracciones llenando con
agua los envases de boing para luego
interactuar y jugar con ellos , por
ejemplo si el profesor pedía que
llenáramos a un medio de el envase de
un litro de boing, ¿qué fracción se
representaría?
PROBLEMA 1
Gustavo fue a una fiesta en dónde la temática era llevar un jugo de 500 ml (boing) para
poder entrar a la fiesta pero al igual que gustavo , Jessica ( su hermana) también iba a ir
a la fiesta y su mamá de ambos no quería comprar dos jugos por separado ya que era
más dinero , entonces ella propuso que sumaran las cantidades de sus jugos y así ella
podía comprar uno solo
¿Qué fracción resultaría de sumar los dos bongs de 500 ml ?
500 ml de jugo =
500 ml de jugo=
𝟏

𝟐 1 litro de
jugo = 1

PROBLEMA 2
Maribel quiere regalarle a su mejor amiga Tania tres jugos boing porque le gustan
mucho, ella le compró un boing de 1000 ml , uno de 500 ml y uno de 250 ml y se los dio ,
Tania tiene en total tres jugos de diferente tamaño pero ahora ella quiere saber cuánto
es el total en litros de jugo ?
1000 ml de jugo =
500 ml de jugo=
250ml de jugo =
