The students must complete the table like the following:
The students must complete the table like the following:
Give Ex-11.2 different problems as homework/ classwork practice problems.<br>
Give Ex-11.2 different problems as homework/ classwork practice problems.<br>
'''Lesson 3'''
(this may take 2 periods)
http://www.commoncoresheets.com/Math/Patterns%20and%20Function%20Machines/Identifying%20Pattern%20Attributes/English/1.pdf
Numbers and generalizations – Use the spreadsheet to work with addition and subtraction and multiplication generalization
Students must make word problems in groups to describe a given expression
Students can work in groups for this number pyramid also - check file
See page 232 of NCERT book used. That verbal/ mathematical expression important to build.
Exercise 11.3 for all students (Do 11.3 with the spreadsheet – discuss some problems)
In groups have children write out expressions for given situations in Page 234 of the book chapter.
Exercise 11.4 based on student level
Introduce equation (based on perimeter of an object) – Show Geogebra file
'''Lesson 4'''
Revisit forming an expression; take the same square example they did above. Extend by making it like this

See this link very useful - http://nrich.maths.org/8111<br>
-How may different ways can you draw?<br>
-How many down (vertical) lines and how many inverted C?<br>
-How many along (horizontal lines) and and how any downs?<br>
-How many squares and inverted C?<br>
-How many match sticks?<br>
*Exercise 11.4 based on student level
*Exercise 11.5 based on student level
'''Lesson 5'''
Expressions involving square<br>
The objectives of this lesson is to show the difference between 5x2 and (5x)2<br>
Use the attached Geogebra<br>
file and use following questions.<br>
What is the side of small square?<br>
What is the side of large square? Explain in terms of small square<br>
What is the area? Of small square? Of large square? Express in variables<br>
(x)² and (factor*x)². How is this different from factor*x²<br>
For the (5x)2 you should keep drawing squares using polygon tool.<br>
Use the following second NCERT textbook<br>
