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.

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.

In this page, the following are explained

 •  grouping of `10` of units to `1` ten

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

number 10 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`. number 10 new block In this course, the purple block is used to represent `10`.

Blue block represents `1` and the grouped purple block represent `10`. number 10 new block 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.

number 11 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`.

number 12 The number represented in the figure is `12`.

number 13 The number represented in the figure is `13`.

number 14 The number represented in the figure is `14`.

number 15 The number represented in the figure is `15`.

number 16 The number represented in the figure is `16`.

number 17 The number represented in the figure is `17`.

number 18 The number represented in the figure is `18`.

number 19 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).

number 20 The number represented in the figure is `20`.

number 24 The number represented in the figure is `24`.

number 32 The number represented in the figure is `32`.

number 47 The number represented in the figure is `47`.

number 54 The number represented in the figure is `54`.

number 65 The number represented in the figure is `65`.

number 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`.

number 70 The number represented in the figure is `70`.

number 70 The picture provides an equivalent form of representing `70`.

number 84 The number represented in the figure is `84`.

number 84 The picture provides an equivalent form of representing `84`.

number 97 The number represented in the figure is `97`.

number 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)

number 100 The number represented in the figure is `100`.

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

number 136 The number represented in the figure is `136`.

number 721 The number represented in the figure is `721`.

number 721 alternate formfamiliarize with the terminology
721

number 721 place value form 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.number 721 place value form

number 1000 The number represented in the figure is `1000`.

`1000` is written as thousand.

number 5361 place value form The number represented in the figure is `5361`.

number 28573 place value form 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 thousandsnumber 28573 place value form An example is given in the figure.
