6. You’re either Good at Maths or You’re Not

September 20, 2017

The Complaint:  

You’re either Good at Maths or You’re Not!………………

………………………………………………………………………….

The Cause:

Most students who said “I can’t do maths’ when I was teaching, didn’t do maths. They talked, penned a tattoo on their arm. Or scribbled in the text book. Today they read texts or play games on their phones under table or fall asleep.

………………………………………………………………………….

The Solution: 

There is no point arguing. Students must ‘see’ they can do maths.  

Do something that grabs their attention, something counterintuitive. Here is one of the BEST revision projects ever for middle school maths students. Remember, the best way to learn something is to teach it.

NB: This post has been updated twice. Disraeli said that if you want to become acquainted with a subject, write about it!!!! Mathspig’s head nearly exploded writing about this subject. But I’ve got it down to its simplest form now. One that Mathspig  finally understands.
