Group Micro-Teaching Lesson Plan

EDCP 342
Micro-Teaching Lesson Plan
Teachers: Yijia, Yeni, Eric
Subject:
Foundations of Math 11
Grade: 11
Date: November 1
Duration: 15min
Lesson Topic
Arithmetic Sequence
Content
  • Operations with fractions (addition, subtraction, multiplication, division, and order of operations)
  • Analyze and prove conjectures, using inductive and
    deductive reasoning, to solve problems
Learning Outcomes
  • Recognize arithmetic sequences
  • Apply the relevant formula to calculate the value of the initial term, the common difference, and the general term of an arithmetic sequence
Materials and Equipment Needed for this Lesson
  • Whiteboard, markers
  • Paper, pens/pencils
  • Worksheets
Lesson Stages
Learning Activities
Time Allotted
1.
Warm-up
  • Check students’ prior knowledge of patterns:
    • If they can recognize the pattern of a given sequence
    • If they can use that pattern to continue the sequence
    • If they can generate a formula from the pattern
  • Examples:
    • Dates of all Fridays in a month
    • Numbers on a car dashboard
    • Any other patterns in everyday life?
3 mins
2.
Presentation
  • What is an arithmetic sequence (a, d, and n)?
  • What is a finite arithmetic sequence?(2, 5, 8, 11) (Use examples from warm-up)
  • What is an infinite arithmetic sequence?(3, 6, 9, 12, 15...)
  • It is harder to locate a specific term in an infinite sequence by counting them. What should we do? ---- Find a general formula!
  • Given t1=a, t2, and t3:
    • Generate a formula for t2 and t3 in terms of a(t1) and d
    • Predict what t4 and t5 will be
    • Predict what t10 will be
    • Find a formula for tn (let students guess first)
  • Tn = t1 + (n - 1)d
                    = tn-1 + d
  • Note that it is a linear function(link to previous lessons if possible)
  • Special Cases: If the given terms are not adjacent, how do we find a and d? Example: Given T2, T5, T7
5-7 mins
3.
Practice and Production
  • Arithmetic sequence activity:
    • Students pair up
    • On a sheet of paper, list the first, second, and fourth terms of their own arithmetic sequence
    • Exchange papers
    • Find the third and fifth terms of the given arithmetic sequence
    • Find a, d, and the formula for tn
    • If time permits, do another round
5-7 mins

Skemp: Relational Understanding and Instrumental Understanding

The advantages of instrumental understanding Skemp lists in this article can be viewed as study strategies for students who want to have easier grades and see apparent progress. This type of learning could help students who have had serious problems with mathematics and just need the grades to pass a course. Although my teaching experience is very limited, I have witnessed quite a few students who say they hate mathematics, and some of those students even think that they would not need mathematics in the real world. They might be right in some way, but if they were taught to learn relationally rather than instrumentally, their mathematical approaches towards the world might have been very different. With instrumental mathematics taught, students might think they understand, but they are not able to apply those concepts they learned to different situations. Lack of this skill leads to memory work and eventually boring classes. In boring classes students tend to strive for ...

Math Art Project - The Magic Path

Our math art project was based on  Margaret Kepner's A Magic Knight's Tour . A knight's tour is a path that visits each cell of the 8 by 8 chessboard once in knight's moves. All the moves are connected with black lines, and we can see that it is a closed magic path, where a starting point can also be an ending point. Observing Kepner's art, we realized that the inner squares change colour every move in a specific order. As there are 8 colours that were used, the colours keep changing, and the sequence repeats after the 8 colours. The background colour also changes. The first 8 outer squares - the first colour being red since the small black circle is the starting point of the path as described - are red, the second 8 are orange, the third 8 are yellow, etc. The colour black is used when the inner shape's colour matches the outer square's colour. In this way, there are a lot of interesting patterns that have been embodied in Kepner's art. It was at fir...
