# OnGo Supplemental Math Videos

February 7th, 2022

Grades 5 and up, with parental supervision

This website provides short instructional math videos that can be used to supplement math studies. The videos consist of a narrated lecture and animations that illustrate the concept being discussed. The videos are enabled for iPhone, iPod and iPad devices for portable, on-the-go learning.

When you get to the website you’ll see a menu of math videos that include topics such as:

• Triangular Numbers (Parts I, II & III) – Elementary explanation of triangular numbers, a general formula for the sum of an arithmetic progression, and a solution to the Recursive equation.

• Mathematical Induction (Parts I, II, & III) – Explains the Method of Mathematical Induction. Discussion of Francesco Maurolico, Pascal and John Wallis, plus Fermat’s Method of infinite descent, etc.

• Weaving Numbers – Explanation of Vedic multiplication or weaving multiplication. Includes Fibonacci’s sieve or lattice multiplication, and more.

• Dimension 2 – Explains how two numbers can describe the position of a point on a sphere, and how one can draw a picture of the Earth on a piece of paper.

• The Fourth Dimension – Mathematician Ludwig Schläfli discusses objects in the fourth dimension.

• Complex Numbers – Mathematician Adrien Douady explains the square root of negative numbers in simple terms.

• Pi – An explanation and illustration of the most famous mathematical constant.

The narrator on some of the videos speaks in a monotone voice with an accent, so we found it necessary to really pay attention to hear and understand the lectures. Fortunately, the animated illustrations help the viewer to maintain focus.

We couldn’t find “about” information on the site, so it’s not clear who is providing the info or why. Currently, there are no advertisements on the site, and all of the videos can be accessed for free, without registration.

This is a helpful resource for supplementing the study of various math concepts.

February 27th, 2021

The University of Texas at Austin – Spanish Proficiency Exercises

This site features a dozen or more free lessons for each of six levels of proficiency in Spanish – everything from Beginning to Superior!

When you get to the site, you will see an introduction that explains this unique program. The lessons are listed by level in a horizontal menu bar near the top of the page. Place your cursor over the level on the menu bar and a drop-down menu displays each lesson in that proficiency level. Click on the lesson and a new page opens.

In each lesson, there is one simplified video interview, plus video interviews of FIVE native speakers using the grammar and vocabulary for that lesson. The five native speakers could be from Spain, Mexico, Central America, or South America. While the video is playing, the captions can be set to Spanish, English, or None. The videos are also available as podcasts for anywhere viewing by iPod.

Unlike most traditional textbooks, this website does not include worksheets or quizzes. However, relevant vocabulary, phrases, and grammar are available in the menu located in the right-hand column of each lesson page. There are plenty of videos to watch without the captions if you wish to practice your comprehension skills!

The entire site can be navigated by means of the “site index” in the upper right corner if you prefer.
