Algebra - Week 2 Lesson 3: Solving Expressions

Objective: This lesson will have students solving expressions. They will be given a value for 1 or more of the variables in the expression. 


Review writing expressions from words.

Be able to write expressions from the following phrases:
A number + 5 = (n + 5)
14 minus a number = (14 - n)
a number multiplied 9 times = (9n)
a number divide by 6 = (n/6)
a number multiplied by 4 minus 2 (4n - 2)
This time give them a value for n (ex. n = 12). What would each of these problems equal?

Algebra - Week 3 Lesson 1: Multiplying and Dividing Variables

Lesson:

This lesson will focus on reviewing last week's content (constructing expressions, simplifying expressions, expanding brackets) and introducing multiplying and dividing variables. 

MULTIPLYING VARIABLES

Ex 1: Multiplying different variables:
  • b x h = bh
  • the variables are written beside each other which tells us they are being multiplied together

Ex 2: Multiplying the same variables:
  • b x b = b2 (b squared)
  • you simply add the exponential values together
  • when a variable doesn't have an exponent that means it is to the power of 1
  • b3 x b5 = b8 (because 3 + 5 = 8)


DIVIDING VARIABLES

Ex 1: 25b / 5 = 5b
  • All you need to do is divide the coefficient (the number in front of the variable b) by 5.

Ex: b5 / b3 = b2
  • We are only going to focus on dividing terms with the same variables
  • You just need to take the exponential value of the first term and divide it by the exponential value of the second term (5 - 3 = 2, so the answer is b2)
