other materials will be needed to carry out the lesson objectives? What
resources will be needed including books, web page links and/or outside
speakers, etc.? 
Resources Basic points and formulas of Number System (Natural Number, Whole Numbers, Integers, Rational
numbers, irrational numbers, Real numbers) Knowledge of divisibility test to factorise All exercises of NCERT Text Book Class 10 with examples. Assignment given by the teacher. Complete Family of
Number System Students can get step
by step knowledge about the number system from this figure. 
STUDENT
ENGAGEMENT What the student does that is consistent with this model:

Number system is used
everywhere in our day to day life. e.g To engage the students
in the teaching learning process, teacher can ask the questions related to
the following points : 1. Calling a member of
a family or a friend using mobile phone. 2. Calculating your
daily budget for your food, transportation, and other expenses. 3. Cooking, or
anything that involves the idea of proportion and percentage. 4. Weighing fruits,
vegetables, meat, chicken, and others in market. 5. Using elevators to
go places or floors in the building. 6. Looking at the
price of discounted items in a shopping mall. 7. Looking for
the number of people who liked your post on Facebook. 8. Switching the
channels of your favorite TV shows. 9. Telling time you
spent on work or school. 10. Computing the interest you gained on your business. Teacher can engage the
student by showing VIDIO on the
NUMBER SYSTEM. Google Meet App : Teacher can use Google Meet App for
AudioVisual interaction with the students.

EXPLORATION What the student does that is consistent with this model:

With this model students
become able to explain :

EXPLANATION What the student does that is consistent with this model:

Introduction Teacher will draw a number line and mark rational numbers on it.
Teacher will ask the class why there are gaps between two rational numbers.
After getting different answers from class, irrational numbers will be
introduced. As all the numbers can ‘not be represented in p/q form, where q ≠ 0 Difficulties in expressing length of the diagonals of certain
squares ( eg. Square of side 1 unit) in the form of rational numbers
led to the discovery of irrational numbers. Irrational numbers seems to fill
gap between rational numbers. Smart board content based on representation of irrational
numbers on number line will be shown. Real no. model will be used to show hierarchy of number system. Explanation Teacher should start the topic with Introduction of number system, Definitions of all types of numbers with explanations. Different types of decimals, terminating decimals, nonterminating but repeating decimals, nonterminating nonrepeating decimals, rational decimals and irrational decimals. Definitions of Lemma, Algorithm, Euclid’s Division Lemma, and application of E. D. A in some word problems. Euclid's Division Lemma: For given two positive integers a and b there exist unique integers q and r such that a = bq + r , where 0 ≤ r < b Explain the Method of finding the HCF by using Euclid’s Division Lemma with two numbers and with three numbers. Definitions of Fundamental Theorem of Arithmetic’s, L.C.M and H.C.F. Method of finding the HCF and L.C.M. by using F.T.A. and verification of the relation H.C.F. X L.C.M. = Product of two numbers. Fundamental Theorem of
Arithmetic: Every composite
number can be expressed as the product of primes and this factorization is
unique irrespective of their order.
Condition of denominator of a Rational Decimal: Denominator can
be expressed in the form 2^{m} x 5^{n}

Teacher
SelfAssessment: How
well did the lesson work overall? What were the strengths of the lesson? What
were the weaknesses of the lesson? How can I improve the lesson for next
time? 
Self Assessment
Techniques : Assignment having three different levels which will include questions from direct application of concept to logical thinking and higher order thinking skills.
