May I first offer you a cup of tea and a biscuit in gratitude for taking the time to read this (offer does not apply to bloggers who just clicked a star under the title photo).
Maths gets a bad press. Although I’m no numerical gymnast, I do enjoy when I can help the kids solve a homework question (By enjoy I mean I shout ‘Boom’, rise from the table and do a victory lap of the room).
I’m not a big fan of dumbing down of text books and turning them into colouring workbooks. I’m sure there is a study out there somewhere to support their academic attributes, but if a text is so good, why must it be revised so often?
The above pictured example shows a fairly straight forward exercise. It’s for first year maths so it is part of the basic maths curriculum.
In the example we are shown a fraction (18/30) multiplied by a whole number (100) followed by the magical appearance of the answer.
I know, it made me angry too, I mean seriously, not converting a whole number into a fraction? What were they thinking?
Are the publishers now skipping basic rules in maths to make them fit into the little colour coordinated boxes.
A fraction must only be multiplied by a fraction, hence 18/30 must be multiplied by 100/1. It’s a rule and by understanding that basic concept it helps further down the line when the maths problems become more complicated.
I wanted to burn the book, such was my outrage, but my daughter wouldn’t let me, said it was a rental or something.
So I dug out my old copy of Text and Tests, reassured by it’s mono chromed bulk we worked through some PROPER examples which resulted in a few more laps around the kitchen, to my daughters’ eternal embarrassment.
