## Lesson plans – Introduction

by on May.04, 2010, under Math, Reviews

My memory is not the best one…and I don’t remember too much from my childhood, but between my most beautiful memories are my grandparents and some school moments I remember smiling nostalgic happily. I know it does not sound great – my husband and many friends are telling me that – but I loved school! I wasn’t the best student, only a normal one with a bit of passion for socializing, math and especially for my math teacher, who used to have a real talent for teaching, but also a great perfume…

Learning the divisibility rules was my first acknowledgment about how fun and challenging math can be. I was 10 years old and I could have “discover” for my self why a number is divisible by some specific numbers.

Our teacher has written on the board a row of numbers and then he has asked us which ones we think are dividing by 2, then by 5, 10, 100, 3, 9, 25, etc. So, we have found together the right answers and
then it came a more “tricky” question: what do you notice at the numbers divisible by 3? There were numbers like: 9, 21, 36, and 201. And this was my moment of glory! I’ve noticed that the sum of the digits for all these numbers is a multiple of 3 (9 – itself, 2+1=3, 3+6=9, 2+0+1=3). So, all my colleagues have written in their notebooks “MY rule”: a number is dividing by 3 if the sum of its digits is a multiple of 3.

This is an example of the many happy moments of my math classes and I am the proof that what is the more important thing in enjoying a subject is THE TEACHER! The best way to teach is to let the impression to the students that they are discovering math’s rules. If my math teacher would have been taught history, then today I would be a history teacher instead of math teacher. After years, I could see also the lesson plans of my teacher: very complete, done with hard work and love!

This is the kind of lesson plan we want to present you in our next materials. We want them to be helpful and joyful as well. I’m looking forward to hear your opinions and suggestions!
