Thought-Process to Discover Knowledge

Welcome to nubtrek.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

### Large Numbers

This page quickly reviews the numbers from 10 to 1000 and introduces grouping of 10 units to 1 ten. The grouping is further explained to understand units, tens, hundreds, etc. This is an important concept to understand numerical arithmetics.

•  grouping of 10 of units to 1 ten

•  introduces the basics to representing numbers in place-value.

There are 10 blue colored blocks in the picture.

There are 10 blue color blocks in the picture. These blocks are packed into a purple block and marked 10. In this course, the purple block is used to represent 10.

Blue block represents 1 and the grouped purple block represent 10. Consider that the smaller blue block is a lower place-value and the larger purple block is higher place-value.

Combining a 10 of lower place value into 1 of higher place value is grouping.

The word grouping means joining and combining together. The blocks were combined into one bigger block.

familiarize with the terminology
grouping

Grouping: 10 of a lower place value is combined to 1 of higher place value.

The number represented in the figure is 11. The purple block is used to represent ten and additional block represents 1. So, the total is 11.

The number represented in the figure is 12.

The number represented in the figure is 13.

The number represented in the figure is 14.

The number represented in the figure is 15.

The number represented in the figure is 16.

The number represented in the figure is 17.

The number represented in the figure is 18.

The number represented in the figure is 19.

Numbers above 10: The numbers above 10 are
11 (eleven),
12 (twelve),
13 (thirteen),
14 (fourteen),
15 (fifteen),
16 (sixteen),
17 (seventeen),
18 (eighteen),
19 (nineteen).

The number represented in the figure is 20.

The number represented in the figure is 24.

The number represented in the figure is 32.

The number represented in the figure is 47.

The number represented in the figure is 54.

The number represented in the figure is 65.

The number represented in the figure is 65.

Instead of laying out all the blocks, the representation gives the count of each of the block. The blocks are of sizes 1, and 10.

The number represented in the figure is 70.

The picture provides an equivalent form of representing 70.

The number represented in the figure is 84.

The picture provides an equivalent form of representing 84.

The number represented in the figure is 97.

The picture provides an equivalent form of representing 97.

Numbers in the tens:
10(ten),
20(twenty),
30(thirty),
40(forty),
50(fifty),
60(sixty),
70(seventy),
80(eighty),
90(ninety)

The number represented in the figure is 100.

Note that 10 of purple blocks are grouped into a orange block. The orange block represents 100.

The number represented in the figure is 136.

The number represented in the figure is 721.

familiarize with the terminology
721

The number represented in the figure is 721. Instead of providing a pictorial representation of the blocks, the value is given in words. The values are hundreds, tens, and units, equivalently representing blocks of size 100, 10, and 1.

Numbers are represented as sequence of digits. If 721 is given, the number of digits are counted as 3 and the number is read as seven hundred and twenty one.

The number represented in the figure is 1000.

1000 is written as thousand.

The number represented in the figure is 5361.

The number represented in the picture is 28573

Large Numbers : The digits in large numbers are

1 (units),
10 (tens),
100(hundreds),

1,000(thousands)
•  1000 thousands
•  10,000 ten thousands An example is given in the figure.
