Insights into Lesson Study
• Introduction: Focus of Lesson
• Student Learning : What we learned about students’ understanding based on data collected
• Teaching Strategies: What we noticed about our own teaching
• Strengths & Weaknesses of adopting the Lesson Study process

Topic investigated:
Introducing a variable in Algebra
![Page 5: Maths Counts Insights into Lesson Study 1. Teacher: Olivia Kelly SHS Maths department Class: First year Maths Ability:Mixed 2](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649d845503460f94a6a65f/html5/thumbnails/5.jpg)
Why this topic?
5
Traditionally, we begin algebra with:- evaluating expressions- adding & subtracting terms- multiplying terms.

![Page 8: Maths Counts Insights into Lesson Study 1. Teacher: Olivia Kelly SHS Maths department Class: First year Maths Ability:Mixed 2](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649d845503460f94a6a65f/html5/thumbnails/8.jpg)
Enduring Understanding:
• Syllabus“The relationships-based approach to learning algebra should culminate in students having a deep understanding of algebra which allows easy movement between story, table, graph and equation.”

Learning Outcomes
By the end of the first lesson students should be able to:• Explore the idea of variable as a symbol that
can stand for any member of a set of numbers• Substitute numbers for variables (letters) to
discover unknown values

Testing for Understanding
Questioning1. What is a variable?2. How did you use your variable machine to
determine the value of your first name?3. Is it possible to change the values of each
of the letters in a variable machine, or are they always the same value?
15

Student learning
• Extension Learning
• The value of the letter can vary! 16

High levels of enthusiasm for - Variable machine- Deriving values for their name- Straight to work, excitement in the room
Lower levels of enthusiasm - Q4 & 5 as they found this more difficult
Motivation

Social Behaviour
• Student pair work• Students enjoyed interaction• They engaged with other pairs trying to find
words with a value of 25 and 100.• Higher than usual noise levels• Some students seemed to lose interest if they
couldn’t crack the code

Topic development
• After the initial introduction of a variable in Algebra, we continued the topic using a patterns-based approach
20

Continued Learning Outcomes
TOPIC LEARNING OUTCOMES…•use tables to explore and represent a repeating pattern •generalise and explain patterns and relationships in words and numbers•write an arithmetic expressions for particular terms in a sequence•find the underlying formula written in words from which the data is derived (linear relations)

Teaching Strategies
What did I notice about my own teaching?1.Considerably more preparation time required than usual2.I felt my role changed in the classroom3.It was difficult to work out different ideas presented by students, so we began the following class with a recap, and used their combined answers. All students took this down
30
![Page 31: Maths Counts Insights into Lesson Study 1. Teacher: Olivia Kelly SHS Maths department Class: First year Maths Ability:Mixed 2](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649d845503460f94a6a65f/html5/thumbnails/31.jpg)
Teaching Strategies
Was it difficult to ask questions to provoke students’ deep thinking?• Yes, as they were all working at different paces• I was nervous that they might ask something I
wasn’t fully prepared for, and steer away from the direction I intended
31
![Page 32: Maths Counts Insights into Lesson Study 1. Teacher: Olivia Kelly SHS Maths department Class: First year Maths Ability:Mixed 2](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649d845503460f94a6a65f/html5/thumbnails/32.jpg)
Teaching Strategies• How did I engage and sustain students’
interest and attention during the lesson?

Teaching Strategies
• How did I assess what students knew and understood during the lesson?
• Directed Questioning• Observation• All students got involved individual work and
pair work

Teaching Strategies
How did I put closure to the lesson?I asked students to answer three questions for homework based on the lesson, intended to recap and reinforce student understanding

Reflections on Lesson Study ProcessStrengths & Weaknesses
As a mathematics team how has Lesson Study impacted on the way we work with other colleagues?• We work closely as a pilot school, but have
collaborated a lot during this task.
