A Father’s Journey with Autism- Chapter 13 In this blog I will discuss about the activity in which we taught Simi the Concept of Addition. Initially we started with the development of number concept from 1 to 100, forward and reverse counting, dictation of 3–4-digit numbers etc which I described in my previous blogs. 1. Concept of Addition: Addition in math is a process of combining two or more…
A parent recently asked me how I taught my child about odd and even numbers in math. Instead of me teaching him or giving direct lessons, my son learn on his own and I guide his learning by providing books, worksheets, and taking exams. My request for all the parents -“The best way to ask for advice from anyone is to ask – how can a particular topic be taught? And, do specify your child’s age and…
Triveni Goswami Vernal Registered Special Educator (A64010) In the previous blog, I had written about the pre-number concepts that are a pre-requisite to developing functional numeracy skills. In this blog, I will write about two important aspects—Math Learning Differences (MLD) and Subitization, that I feel are equally important in helping an individual develop and build upon their functional…
Of course, dear!

K-means is one of the simplest unsupervised learning algorithms that solve the well known clustering problem. … The main idea is to define k centroids, one for each cluster. These centroids shoud be placed in a cunning way because of different location causes different result.
-
The k-means clustering algorithm attempts to split a given anonymous data set (a set containing no information as to class identity) into a fixed number (k) of clusters. Initially k number of so called centroids are chosen. A centroid is a data point (imaginary or real) at the center of a cluster.

The concept of overfitting refers to creating a model that doesn’t generalize to your model. In other words, if your model overfits your data, that means it’s learned your data too much - it’s essentially memorized it. This might not seem like it would be a problem at first, but a model that’s just “memorized” your data is one that’s going to perform poorly on new, unobserved data.
-
Underfitting, on the other hand, is when your model is too generalized to your data. This model will also perform poorly on new unobserved data. This usually means we should increase the number of considered features, which will expand the hypothesis space.

As I am currently completing my teacher education program, my views on math is that math can be incorporated in a variety range of topics. Math concepts can be found everywhere and because math revolves around us, it is important for me, as a future educator, to teach future students to strategize, critically analyze and develop mathematical relationships between the problems being solved and the real world. I noticed that math does not have to be a drag, if you sit down, have discussions and dissect the problem as a whole where you can learn from your peer’s perspective on their own mathematical thinking and how they arrived to a solution that you might not have thought of. In addition, as a future educator, it is important for me to build upon mathematical knowledge in order to implement meaningful lessons. By using different learning techniques to engage students in critically analyzing, thinking and understanding math concepts, I will build a safe learning environment that will encourage children to openly discuss their own approaches to math problems.
As I continue to reflect upon my past, I learned that memorizing number facts could only help you in the short-run. Children need to have an understanding on how to arrive to the solution of mathematical problems. However, if there are other ways to arrive to the solution, how can it be demonstrated so that students can use it to their advantage? Future educators need to take their mathematical teaching approaches above and beyond and take into consideration that math is not only about procedures and learning the skill to solve these problems. Instead, we need to come together and begin to realize that math is more than just a set of problems to be solved. It is the idea that math can be applied to real world situations (Small M., 2013, p. 6).
Not much visible progress this week – busy learning Flash/ActionScript to make a better/very interactive infographic about factorials. Still flushing out the details of what and how. Maybe letting the user choose which path each object takes (out of the x possible paths visualized)? More ideas to come…
