** No. 1 UK tennis star Andy Murray is currently playing in the Melbourne Open. **

**Mathspig often pops along to watch the tennis. **

Andy Murray’s Serve by Carineo6

# Could you return Andy Murray’s serve?

According to Wikipedia Andy Murray’s fastest serve speed is:

Andy Murray = 233 km/h (145 mph)

Keep in mind the fastest female tennis serve by Barbora Záhlavová-Strýcová is a very respectable 225 km/h (140 mph).

Go **here** to see why this simplified calculation works!

Mathspig tested her reaction time **here**. TRY IT!

Mathspig’s best, best, best reaction time = O.33 sec

## Could Mathspig return Andy Murray’s serve?

## Nooooo!…………………………………………………………………….

## I’d be hit in the head by a speeding tennis ball

## before I even moved.

But I’m a pig. I got the best service **GRUNT!** Ha!

#### 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!

** 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?

### 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.”

## Readability Harry Potter: Method 1

### Break the above text into sentences. Count the words, sentences and syllables.

### Word Count =

### Sentence Count =

### Syllable count =

### The syllable count is tricky. You will find my sentence-by-sentence count here.

## Readability Harry Potter: Method 2

### You will still have to do a sentence count, but you can cut and past the text into the following:

### and

### Results:

### Word count = 138

### Syllable count = 194

### Sentence count = 14

## Readability Harry Potter: Method 3

### You can calculate the Flesch Kincaid Score by cutting and pasting text here or here:

### Here is the text from a Grade 3 Math Test:

### Math formative.

### I can use multiplication strategies to help me multiply.

### I can use the structure of a word problem to help me solve it.

### Solve the word problem below. Be sure to show your work. Julie bought 7 packages of cupcakes. Each package has 4 cupcakes in it. How many cupcakes did Julie buy?

### Flesch Kincaid Score = 81.4

### Grade Reading Level = Grade 5

### Reading Age = 10 – 11 years

### This is a bit tough for Grade 3 students. Perhaps more Maths tests should be tested for AGE READING LEVELS!!!!!
