On April 12 2017 16-year-old Davis Cripe collapsed at school in South Carolina and died later in hospital.In the span of two hours, Davis drank a cafe latte from McDonald’s and a large Mountain Dew, then “chugged” a 16-ounce energy drink when he got back to art class.
Here, assuming Davis drank large sized drinks, is the lethal caffeine consumption.
NOTE: Davis lived in the USA where standard drink volumes are slightly different to Australia & UK. The USA volumes are used here converted to litre and ml.
The official cause of death was “caffeine-induced cardiac event causing a probable arrhythmia,” the coroner concluded. Source: Washington Post
Caffeine can kill.
WARNING: “Mixing caffeine with alcohol is a dangerous practice because it may lead to higher levels of alcohol consumption as the person often believes and feels they are more alert,” said Dr Robert Glatter, ER doctor at Lenox Hill Hospital, NYC . “The risk of alcohol poisoning increases as people consume more alcohol because they feel the caffeine will keep them awake and alert.” Source: USA Today

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.
Students doing repetitive text book exercises without using maths to solve REAL WORLD problems.
The Solution:
You are going to use this maths NOW…………………..

How much blood can YOU lose and survive?
………….METRIC UNITS
Remember the best calculator to use is the WEB 2.0 Calculator as it shows the worked equation as you go.
CAREERS: It’s not only health workers who need to understand these calculations, but also creatives running health campaigns online, on TV, radio and in magazines.
TOPICS: Decimals, %, algebra, vol, weight units (METRIC)

But my favouritest ,developed by Patrick Len, is using m&ms to demonstrate half life in radioactive substances and therefore write an exponential equation.
m+m ACTIVITY:
Throw a fixed no. m&ms on a table. Mathspig chose 128 m&ms for a very good reason. Eat the ones with the m showing. Count remainder. Throw again. Eat the ones with the m showing. Count remained. Keep doing this. You will end up with results like the following. (Not identical as chance is involved)
Wow! m&m’s and exponential equations. How yummy is that!!!!!!
