October 11, 2017

The Complaint:…………………………………………………………

Too many different ways to do the same thing

………………………………………………………………………………………….

The Cause:……………………………………………………………….

Often, students , who are struggling with a concept, find it even more challenging when changing grades and/or schools because a new teacher uses a different method to the one they were taught.

eg. Long Division must have the most ridiculous number of methods for doing it.

Add a multi-cultural classroom and even more confusion results.

The Solution:

Find the method that works for you. Stick with it and practice, practice, practice.

eg. Long Division

THE LEGO ARGUMENT:

It would be tragic IF  Lego blocks only had one solution. That is IF 6 Lego blocks could only be arranged in one way. In fact, the number of possibilities of arranging 6 blocks is MIND EXPLODING!
