More Math Brain Glitches

More examples of how you can’t take your brain seriously sometimes.

Addition Error

p1.1
First column: 6+9+8+9=42?

 

Division Error

p1.2
(4 goes into 6) 4 times?

 

Copying the problem incorrectly

p1.3
130.59 was supposed to be 139.59

Subtraction Error

p2.1
14-8=2?

The math doesn’t match the question.

p5.1p5.12


Misreading the given facts.

p6.1

p6.2
How did the 63 fish become 64?

 

Misreading the number line.

p12.1
How many lines after 0.3?

Failure to regroup

p15.1
7 + 5 = 2 carry the 1

Failure to count decimal places

p16.1
1 place + 1 place = ?

Always check the easiest problems

p16.2

Math Brain Glitches Illustrated

 

OK, here are a few examples from the minds of some very brainy math students working way above grade level:

Example 1: Move on before you finish the problem

Example 2: You got WHAT when you subtracted?

Example 3:  20% the same as /20?

Example 4: Answer only part of a 2-part question.

mg3

Example 5: Are you sure that’s lowest terms?

mg1

Example 6:  We love equivalent fractions.mathglitches4

I keep sayin’, “Check your answers to the easiest problems. Those are the ones you’re going to miss.”

 

 

Math Brain Glitches

Last week my advanced math students completed another unit assessment.  These kids are amazing, but every one of them got some answers incorrect because of brain glitches.  There’s no reason why just about every one of the students couldn’t  have gotten all of the answers correct.

I’m going to ask for their tests back, scan their answer sheets, and snip out the ones they missed.  I’ll upload them here and show you what I mean.  Should be pretty interesting.

Adolescent Brain Development

In order to most effectively teach the students in my advanced math class, I need to have a better understanding of adolescent brain development.

These students are not just ahead of their peers as far as math skills go. It is possible that the massive rewiring and efficiency upgrade their brains are experiencing is also ahead of schedule compared to other students their age.
