## No Frills MATHs SKILLS for Parents 2 : Algebra

May 4, 2022## No Frills MATHs SKILLS for Parents 1: Super Easy Long Mult and Division

April 27, 2022Go to **BASIC MATHEMATICS** here. It will take you through basic maths by your Grade level.

NB. If you can’t remember how to ‘borrow the 1’ for division or ‘carry the 2’ for multiplication here go back to the link above.

## What do the Sydney Opera House and Freddie Mercury have in common?

November 6, 2018Freddie Mercury is back in the news with the release of the new biopic BOHEMIAN RHAPSOSDY. ( Mathspig gives it ⭐⭐⭐⭐⭐. But I’m a Freddie fan. ) So Freddie and the Opera House? What do they have in common?

NOTE: Uncanny likeness of biopic actors to the real Queen!

According to **intmath** The **Sydney Opera House** is a very unusual design based on slices out of a ball. Many **differential equations** (one type of integration) were solved in the design of this building.

You will never see a better parody of Queen’s ICONIC song BOHEMIAN RHAPSODY than **Calculus Rhapsody** By Phil Kirk & Mike Gospel (below).

And if you need to be reminded of the maths you will find links to texts **here**.

## Learning Jump Strategy from a Young Mathematician

June 8, 2018**Mathpig just learnt this from a young Mathematician age 9.**

**It is a great way to do maths because you are thinking ‘Mmmm! How can I work these numbers.’ **

**Getting maths students to think about what they are doing is so much better than just having them guess ‘ Arrrr! Whatever. Click B.’**

**More jump strategy information here.**

**This will be very useful later when it comes to a similar method used to simplify long division:**

## Trick 5: Cool Math Trick

June 4, 2018### Requirements: A Pack of Cards and a willing assistant.

### Take 10 cards from pack including the 10 Diamonds.

### Lay out card in 3 columns in a pattern of 4 down, 2 down, 4 down.

### Put the 10 Diamonds at the top of the left hand column.

### Group students around. You turn your head away and ask a student to point to a card.

### You carry on, think allowed and then ask your assistant to point to cards asking:

### Is it this one?

### No.

### Is it this one?

### No.…………………………………………………………………………………

### When your assistant points to the 10 Diamonds he will show you the position using the diamonds. The cards are laid out on the table in the pattern of the diamonds on the 10 Diamonds.

### Whenever your assistant asks is it this one? You will know.

## Trick 8: Spooky Maths Magic

May 4, 2018# Spooky Maths Magic

### Requirements; Smart board/data projector.

### This is mental maths, but not hard maths. You can play this video by Marco Frezza directly to the class.

### It may not work on everybody, but it would be very interesting to see how many students are fooled by this spooky magic man.

## 8a. Calculate Your Daily Iron Intake

August 19, 2017# The Complaint

## 8a: 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.

# Calculate Your Daily Iron Intake

# TOPICS: Decimals, %, weight units (METRIC)

Some information you need.

Iron (Chemical symbol:Fe) content in food is recorded in mg because there are only small amounts of iron in food.

1 g = 1000 mg

eg. 1 paper clip = 0.5 g = 500 mg

Iron in 2 teaspoon peanut butter = 0.19 mg

# WORKED EXAMPLE: Breakfast

## 1. Tube Cube

February 17, 2016#### The Tube Cube is made from straws and hat elastic (Steps 1 – 9 below). The effect is quite amazing. The TUBE CUBE can then be used to make a CUBIC BUBBLE here.

#### Don’t show your Middle School students these instructions. Just give them access to some straws, hat elastic, rulers and scissors and ask them to make and then photograph their cube. That’s the challenge Mathspiggies. But the end result (See Step 9) is awesome.

#### Step 8: The TUBE CUBE can be flatened into a hexagon.

#### Step 9: The TUBE CUBE can be turned into an art work. This pic was taken in daylight. The cube was positioned at an angle on a black sheet of paper with one corner set in Blu Tack. WOW!

## 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?

## 4. The Harry Potter Algorithm

November 25, 2015### Here is the Harry Potter Text:

*Harry Potter and the Sorcerer’s Stone, *J.K. Rowling

“Have you ever seen anything quite as pathetic?” said Malfoy. “And he’s supposed to be our teacher!”

Harry and Ron both made furious moves toward Malfoy, but Hermione got there first – SMACK!

She had slapped Malfoy across the face with all the strength she could muster. Malfoy staggered. Harry, Ron, Crabbe, and Goyle stood flabbergasted as Hermione raised her hand again.

“Don’t you *dare* call Hagrid pathetic you foul—you evil—”

“Hermione!” said Ron weakly and he tried to grab her hand as she swung it back.

“Get *off* Ron!”

Hermione pulled out her wand. Malfoy stepped backward. Crabbe and Goyle looked at him for instructions, thoroughly bewildered.

“C’mon,” Malfoy muttered, and in a moment, all three of them had disappeared into the passageway to the dungeons.

“*Hermione*!” Ron said again, sounding both stunned and impressed.”
