Entry: Micro Teaching in Pairs

Micro Teaching Criteria
Name: Jacob & Julie
Topic: Multiplying Fractions and Mixed Numbers


Objectives & Goals
The purpose of this session is to introduce the students to multiplication of various fractions, including mixed numbers. The subsequent lesson (which we won’t do) would teach them about division.
Hook
I will introduce the lesson by showing them a fraction of the board (eg. 5 x ⅓) and ask them what this means in math. I will then explain that it is the addition of ⅓ five times (ie. ⅓ + ⅓ + ⅓ + ⅓ + ⅓), just like regular multiplication.
Materials
To teach this lesson, it is suggested that you have a whiteboard and marker.
Prior Knowledge Check
I would check that students: a) Understand what fractions are and b) Know how to add and subtract fractions.
If these are met, we can continue the lesson after a short refresher. If not, we would spend a bit of time on that a it is a required prerequisite.
Activities
  • 2 Minutes: I will explain that multiplication is just addition. I will say that this is also true of fractions and that they know how to add fractions.

  • 2 Minutes: I will do an example. (6 x 1) is just 6 units by 1 unit

If you count the boxes, you will get the answer of 6. Now for (6 x ½) you can simply cut this in half either way:

If you count the half boxes, you will have 6 of them, which equals 3.
  • 2 Minutes: I will show them that it works for only having fractions as well, such as (½ x ½):

  • 2 Minutes: I will show them the formulaic approach that they will apply, now that they see the methodology: You simply cross multiply. If there is a mixed number, just turn it into an improper fraction first.

  • 6 Minutes: I will give them an activity on Kahoot and review at the end.
Ideas and Skills
They will learn the basics of multiplication of fractions. It will be a culmination of addition of fractions, multiplication, and mixed numbers/improper fractions. This will reinforce algebraic skills.
Closing
The closing section will be at the end of the Kahoot activity. We will check their learning progress and use it to prepare the subsequent lesson.
Assessment
I will assess the students’ learning by seeing if they understand the method during Kahoot. This assessment will be used to determine the amount of homework to assign as well as if the following lesson should advance to division of fractions or further development of multiplication.
