Day 12 Numeracy (Exponents and Order of Operations)

In the expression above, the 2 is called the base and the 3 is called the exponent. We would say that expression in English as, "2 to the third power", or "2 cubed".

Students will be given several examples of bases and exponents to solve together as a class.

Order of Operations

The instructor will write the following on the board:

John said Kaylon is tall

The instructor will then ask the students to identify which person is tall. Then the instructor will punctuate the sentence in two different ways:

John said, "Kaylon is tall." (Kaylon is the tall one)

"John", said Kaylon, "Is tall". (John id the tall one)

The instructor will then write the expression 4 + 5 x 2 , and then solve it two different ways,

9 x 2 = 18 ----------------------------4 + 10 = 14

The instructor will then explain that there is a particular order for us to do mathematical operations, and describe the anagram, BEDMAS.

Brackets

Exponents

Division

Multiplication

Addition

Subtraction

Students will then be given problem set 1.7 from Basic Mathematics #6, p. 79 & 80. The first questions will be done as a group, and then the students will finish the questions on their own.
