Kirigami and Origami

We had a visitor named Ravi Alugnati a very respected resource person in Math and Science languages and also does puppetry hands on activities. He showed us some of the things he had built in Kirigami We made different shapes both in Kirigami(cutting paper) and Origami(olding paper) with his guidance. The 8th and 9th graders of Udavi and some children in Isai Ambalam also enjoyed making different shapes. I found Origami little bit tougher than Kirigami as the steps to build a shape/object is more complex. I also got a feedback from him about my teaching when I was taking class for the 3rd graders in Isai Ambalam. The feedback was useful.

Multiplication using Ganit Mala

I used the Ganit Mala with the 3rd graders of Isai Ambalam to demonstrate multiplication. They were able to understand that multiplication is a sum of additions. They were able to write 2-10 multiplication tables. Some children worked in pairs and some worked alone. They were fairly engaged with the material they were using.

They were also able to do 2 digit addition and subtraction using the Mala.

Cubes Rods Plates – 3rd grade

I introduced the Dienes blocks to the 3rd graders to get a sense of ones, tenths and hundreds. Each cube is one, a rod is a ten and plate is a hundred. I asked them the following questions

  1. How many cubes can make a rod?
  2. How many rods can make a plate?
  3. How many plates make a cube?

Then we noticed that the pattern repeats itself : cubes – rods – plates – cubes – rods – plates ….. and that everytime it increases by 10 orders of magnitude.

The children had fun trying to keep the blocks in their hands. Some children were not able to hold it but they all tried.

Leaves with 3rd graders

The 3rd grade children of Isai Ambalam School collected different leaves from the school campus. They were able to differentiate the shapes, colour and texture of the leaves. We watched a video on why leaves change yellow in colour. They got to know new words like stem, branch, root, chlorophyll etc.. They were able to draw the different parts of the plant in their notebook after watching the video. We also made made an Herbarium model after collecting green leaves and drying them in their notebook/book

Visit to the Science Exhibition Express on Climate Change

We from Isai Ambalam School made a visit to the Science Exhibition Express on ‘Climate Change’ that arrived in Pondicherry. We took the children from 3rd  grade to 7th grade from Isai and 10th graders of Udavi School also joined along. Most of the teachers also came along. Every STEM Land – AAD person were assigned 4 children so that they could discuss and explain about the things they are seeing in the exhibition. Each group was supposed to have a Udavi child and atleast a girl so that the group is balanced and diverse. In our group we learned about effects, causes and adaptation methods of climate change. It was very interesting for myself and my group as we all learned new things that day!

Painting the clay room – Sat School

The clay room before we started to paint

Naveen and I took the help of the 4th graders to paint the clay room we are setting up in Isai Ambalam School. We scrapped the inner side walls of the room so that all the loose particles/paint came out. We then mixed white cement with water to cover the places where there were holes and black marks. Then we started painting the side walls. The children took a certain portion of the wall to paint(depending upon the height). Some also took a complete wall for themselevs to paint. Initially the children were worried that they would get paint in their hand/body. But once they took the paint brush in their hand, they were quite involved and didn’t woory much as would wash away everything in the end!

 

  

Animals with 3rd Grade

Naveen and I showed a video on vertebrate and invertebrate animals to the 3rd and 4th graders. The differentiated birds, fish, amphibians, reptiles and mammals. The children were able to give examples for each of the categories. After watching the video, I asked the 3rd graders to draw something they learned or understood from it. Below are some of the pictures they drew.

Two HTTP Request Methods: GET and POST

GET – Requests data from a specified resource
POST – Submits data to be processed to a specified resource
In computing, POST is a request method supported by the HTTP protocol used by the World Wide Web. By design, the POST request method requests that a web server accept the data enclosed in the body of the request message, most likely for storing it. It is often used when uploading a file or when submitting a completed web form.

Note that the query string (name/value pairs) is sent in the HTTP message body of a POST request:
POST /test/demo_form.php HTTP/1.1
Host: w3schools.com
name1=value1&name2=value2
POST requests are never cached
POST requests do not remain in the browser history
POST requests cannot be bookmarked
POST requests have no restrictions on data length

jQuery Syntax

The jQuery syntax is tailor-made for selecting HTML elements and performing some action on the element(s).
Basic syntax is: $(selector).action()
1) A $ sign to define/access jQuery
2) A (selector) to “query (or find)” HTML elements
3) A jQuery action() to be performed on the element(s)

$(this).hide() – hides the current element.
$(“p”).hide() – hides all <p> elements.
$(“.test”).hide() – hides all elements with class=”test”.
$(“#test”).hide() – hides the element with id=”test”.

$ is just a shortcut for jQuery. The idea is that everything is done with the one global symbol (since the global namespaces is ridiculously crowded), jQuery, but you can use $ (because it’s shorter) if you like.

// These are the same barring your using noConflict (more below)
var divs = $(“div”); // Find all divs
var divs = jQuery(“div”); // Also find all divs, because
console.log($ === jQuery); // “true”
