## It is Xmas … Ah! The Joy of Algebra!

December 5, 2019**Great Math Xmas Ornament Ideas for Middle School here @ MathEqualsLove blog.**

**Mathematicians can make mountains out of mince pies, but in this case Dr Eugenia Cheng, who is Professor of Pure Mathematics at the University of Sheffield, UK, makes it look fun. The video clip includes some great Middle School Maths that you can eat.**

## 8b. How much blood can YOU lose and survive? ……………METRIC

August 16, 2017# The Complaint

## 8b: When will I EVER use this maths?

# The Cause:

#### 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.

## Best Ever Fun with Algebra

June 9, 2016### We all know about gravity. We worry about gravity.

# GRAVITY CHALLENGE

### If someone holds a pen in your hand like the gif below, then drops it,

### I bet, if you keep your hand in the one position, that you can’t grab it!!!!

### The maths is soooo beautiful.

**All objects and bodies drop at the same rate of acceleration, g = 9.8 m/sec**^{2}

^{2}

### d = distance travelled by falling object (m)

### t = time taken (sec)

**You can test your reaction time on THE REACTION TIME CLOCK HERE.**

## 1. Hokey Pokey Algorithm

November 25, 2015

** Here’s the Hokey Pokey:**

You put your right foot in

You take your right foot out

You put your right foot in

And you shake it all about

You do the hokey pokey

And you turn yourself around

That’s what it’s all about!

**Why are algorithms as easy as the Hokey Pokey?**

**Because the Hokey Pokey is an algorithm or a set of steps that have to be taken to complete a task (see below) and the task is having fun and/or being really embarrassed by your parents in public. Whatever!**

For more information about algorithms go to the Khan Academy here.

** READABILITY ALGORITHM**

We are going to look at texts including a maths test to check their readability. Here are just a few songs with their age and Grade readability scores:

Hokey Pokey (above) = Grade 3 = 9 yo

Frosty the Snowman = Grade 5 = 11 yo

Hello by Adele = Grade 5 = 11 yo

Wildest Dream = Taylor Swift = Grade 3 = 9 yo

Russians* Sting = Grade 6 = 12 yo

* Most complicated lyrics I know. Any other suggestions?

# How much chocolate is too much?

#### Firstly, the darker the chocolate the more Theobromine it contains.

#### According to About Chemistry:

#### Based on highest possible toxicity:

White Chocolate: insignificant

#### .

## Milk Chocolate 1-5 g/kg

#### 200gm block = 1 gm per block

……………………………………………………………………………………….

## Dark Chocolate 10 g/kg

#### 200gm block = 2gm per block
