Teaching loops and efficiency

Hola Marcela
Con mis estudiantes realizamos el mismo trabajo todo oral ya que tengo a cargo un primero básico y los conceptos de algoritmo y bucles deben ser muy fáciles de entender para ellos y como el algoritmo es un conjunto de instrucciones paso a paso realizamos la actividad de las galletas, donde solicitamos el comedor de la escuela y en conjunto con los apoderados mas los carteles de la receta incluimos el texto instructivo realizamos este delicioso alimento y de igual manera introduzco el concepto de bucles en fin creo que todo va hacia un mismo logro independiente que se realicen las mismas cosas.

I would work on a code together as a class that specifically has a lot of repeated steps that we can shorten with a loop or the “repeat” block.

Expilcaría el conceptode Bucle a mis estudiantes como un ciclo repetitivo.

I would use their daily routines and find other things like the mailperson or school bus etc as examples of things that are constantly doing the same thing over and over.

Explicaría el concepto de bucle de dos maneras: una de ella sería entonando una canción favorita por los estudiantes, pues se debe cantar una estrofa y luego el coro de la canción, otra estrofa y una vez más el coro de la canción.
La segunda forma sería con una dinámica grupal llamada “pie, pie ,pie…” que hace bailar una secuencia de pasos con distintas partes del cuerpo, siempre regresando al “pie,pie,pie” luego de decir otras partes del cuerpo.

Los bucles en forma simple son repeticiones que te ayudan a se mas simples las ordenes dadas y lo ejemplificaría en una clase de educación física donde realizan repeticiones de ejercicios en diferentes estaciones

I teach loops in elementary physical education all the time. During our fitness unit we talk about creative ways to keep our heart rate up- circuit training. We list numerous upper and lower body exercises. Each exercise is demonstrated step by step to to execute the skill correctly forming a sequence. Students rotate from station-to-station after a set time - algorithm. Students will eventually finish all stations (loop) and repeat the process several times.

To teach the concept of loops to my 6th graders, I would begin by connecting to prior learning from the unplugged lesson in Course F, My Robotic Friends, as the lesson suggests. I would explain that there is a strategy to simplify their algorithms by identifying repeating symbols. Next, I would take a step back and hold a discussion about repetition in other areas of life: dance steps, patterns in math, construction, sports, etc. To incorporate some movement and fun, we could draft an algorithm for a dance routine that students are familiar with, like the Cupid Shuffle, Cha Cha Slide, a Fortnite dance, or something else the students come up with. Now that they are engaged, I would revert back to the lesson, My Loopy Robotic Friends and carry out the activities using our work from the previous unplugged lesson. By the end of the lesson, students will be able to identify loops as repeating patterns in an algorithm.

As a fun follow-up, I’d also introduce the Dance Party game on Code.org and give them some free time to create using loops.

I enjoyed learning about loops in this module! I especially liked how this concept could be applied to everyday life, such as in our morning routines: brushing hair 20x to get out knots, putting breakfast in mouth and chewing 20x, etc. I think one way we could make this concept of looping even more relevant would be encouraging students to think of repetitive actions they do every day. I teach 3rd grade, and I know that student buy in skyrockets when the learning is relevant and personalized to the lives of my learners.

My idea is for students to brainstorm loops that we can observe in the classroom! I am thinking some examples could be passing out worksheets in mailboxes to every student (tedious!) or numbering lines on notebook paper for a spelling quiz (just to name a couple!) I know my students would have many ideas on this topic, and I look forward to posing this question to them in order to make the concept of loops more relevant and meaningful.
