¿LO TOMAS O LO DEJAS?



Este juego se llama lo tomas o lo dejas, este lo realice en la asignatura de ciencias naturales lo realice con materiales reciclables, marcadores, temperas,y  regla. Este juego contiene dos dados, cuatro fichas, instrucciones, caja,  25 consejos y 25 preguntas de los temas vistos en clase. Este consiste en llegar al final del recorrido con una sola ficha lanzando  los dados, también habrán unas casillas de color amarillo donde responderás la pregunta que te correspondió y perderás la cantidad de turnos correspondientes, por lo contrario si caes en una casilla verde te tocara un consejo y avanzaras cuantas casillas te correspondan. También habrán algunos atajos en medio de la pista, solo pasaras por ahí si llegas al numero correspondiente y pasaras por este en medio de tres pasos. El primer jugador que llegue sera el ganador 
Este juego me ayudo en muchos puntos de vista, me ayudo a darme cuenta que uno también  aprende  haciendo esta clase de trabajos ya que uno se centra mas en el tema dado. Aprendí y repase los temas vistos en clase de un manera menos común pero muy efectiva. 
Uno no tiene que cerrarse en una sola manera de aprendizaje pues dado este caso se puede demostrar que  hay muchas maneras.

ingles me parece que este momento en el que nos enteramos de donde provienen, la historia e ideologías de muchas de las tribus urbanas que se presentan mucho hoy en día  nos hizo entender que las algunas "modas" no nacen de un día para otro sino cada uno tiene su historia.
Como mi vida de adolescente me ayudo a entender que no todos debemos pertenecer a cierto grupo pues no todos tenemos los mismos gustos e ideologías, no tenemos que hacer algo por pertenecer a algo, muchas veces los adolescentes por ser aceptados en la sociedad hacen y dicen cosas que no son acorde a su personalidad, por esto se han presentado varias problemas en los adolescentes (ejemplo; homosexualidad, drogadiccion, etc.). Solo puedo decir que esta profundización a la sociedad que nos estamos exponiendo me ayudo a responder ciertas inquietudes y a darme a entender que tengo que desarrollar mi identidad y no dejar que otros lo hagan por mi.



I think this time when we found out where they came from, the history and ideologies of many urban tribes have much nowadays made ​​us understand that some "trends" are not born overnight but each has a history. 


As my teenage life helped me understand that not everyone must belong to a certain group as not all have the same tastes and ideologies, we have to do something to belong to something, often teenagers to be accepted in society do and say things that are not according to your personality, so there have been several problems in adolescents (eg,. homosexuality, drug addiction, etc.). I can only say that this deepening society we are exposing helped me answer some concerns and let me know that I have to develop my identity and not let others do it for me.
