수업 소개

Learners are introduced to PEMDAS or BODMAS as a tool to remember the order of operations. Together, numerous expressions  are evaluated using the rules with clear step by step explanations.  Learners are encouraged to participate and explain the rules they are using.  Next, learners use their PEMDAS tool to work as a group or in pairs with the activity sheet of expressions.  This activity requires the learner to break down the expressions into simple steps and communicate these steps.  At the end of each turn, the learners should arrived at the same number.  The lesson ends with a review to assess understanding.

This lesson uses slides for visual support and discussions.  No prior knowledge of the order of operations is needed. This course could also be used as a review.

I am a passionate educator with a love for teaching and tutoring mathematics.  I am a certified secondary mathematics teacher who has guided learners from 10 to adults since 2012.  I specialize in helping learners overcome common stumbling blocks encountered in middle school and high school math.  I provide individual support through one-to-one tutoring sessions and offer weekly small group lessons covering core math subjects.

I have a bachelor’s degree in math and computer science and master’s degrees in operations research and secondary mathematics education.   This extensive background enables me to offer a comprehensive approach in my math lessons.  I have a passion for international education.  I have taught and tutored students from diverse cultural backgrounds in the Netherlands, England, the United States, and through online platforms worldwide.  I embrace the opportunity to incorporate the experiences of my learners into my math lessons, thus creating a globally enriched learning environment.  

In my classroom, I guide learners to become active participants and explore math concepts through investigations.  I encourage students to share their ideas during the lessons to build their mathematics skills, confidence and communication abilities.  When tackling math problems together, I encourage discussing strategies and alternative methods to develop critical analytical thinking.  This approach ensures that all learnings’ styles with the class are acknowledged and addressed. 

Teaching for me is similar to working on a complex puzzle.  With each question posed by a learner, I search to identify their knowledge gaps and connect the missing puzzle pieces.  I formulate clear explanations and guidance by asking probing questions that direct learners towards the solution.  I am committed to lifelong learning and continuously review and refine my teaching strategies based on student feedback and questions. 

I am excited to explore the world of mathematics with your learner.
