GIST OF LESSONS
Mathematics
CLASS – VI
Taught during the period 6th April, 2023 to 30th June, 2023
(Topic covered commonly in all sections)
a. Number system
b. Factors and Multiples
c. Line segments, Ray, Lines
d. Parallel lines
Topic: NUMBER SYSTEM
Following sub-topics were covered under Number System with explanation and
examples. Problems were given from R S Agarwal.
1. Notation: writing a number in figures
2. Numeration: Writing a number in words
3. Hindu-Arabic system of writing numbers: we use here symbols like 0, 1, 2,
…9, called digits or figures to represent any number.
4. Numerals: A group of digits, denoting a number is called a numeral.
Example given to write a numeral in expanded form from place value table.
5. Number system extended further with examples
6. Periods: Crores, lakhs, thousands and hundreds are known as periods
, 7. Separating periods in Hindu-Arabic System:
(Crores), (Lakhs), (Thousands), (Hundreds + Tens + Ones)
Examples given.
8. Face value of a digit in a numeral: The face value of a digit remains as is,
whatever place it may be occupying in the place-value chart
9. Place value of a digit in a numeral: the place value of a digit in a numeral
depends upon the place it occupies in the place value chart, explained with
examples.
10. International system of numeration explained with examples.
11. Selective Problems from Ex - 1A from R S AGARWAL
12. Comparison of numbers
The number with fewer number of digits is less than the number with larger
number of digits.
If the number having same number of digits, then,
(i) Compare the digits at the leftmost place in both the numbers.
(ii) If the leftmost digits are equal then compare the second leftmost.
(iii) Again, if second leftmost are equal then third and so on until
13. Examples given from EX-1B
14. Word problems on number operations: several examples shown and given
to solve in the class.
15. Examples done from EX-1C
16. Estimation: Estimation of a number were shown in the following forms
with examples from R S Agarwal EX-1D and 1-E.
a. Rounding a number to the nearest ten
b. Rounding a number to the nearest Hundred
c. Rounding a number to the nearest Thousand
d. Estimation of products of two numbers
