There is only one prime number that is even which is 2.
There are 45 prime numbers which end in each of the digits 1, 3, 5, 7, 9.

Materials needed: flashcards with maths equations (e.g. 5+3×8)

Setup: shuffle the flashcards and put them face down

Rules:

Each player takes turns in a circle to pick up a flashcards card from the middle deck and flip it to reveal the equation

If the player that flipped it answered it correct, they take the card, of they get it wrong, the other players can steal the card by answering the equation correctly

Objective: be the first player to collect 20 cards

My wallet is a rectangles and my rubber band is a circle

You will need a dice, a piece of paper and a pencil for each player

How to play?

Each player takes turns to roll the dice twice

Use the numbers you have rolled and make a equation using any of the four operations

After solving your equation write it in the piece if paper you have

First player to reach a 100 wins!!

Thinks to take note of

The answer you got after you solved your equation must be a whole number

You must use both the numbers you rolled to make the equation

You can use only one operation each round

I would call my code the 'alphbet x 3'

This is how my code works

1. Convert all the alphabets to numbers

( A=1, B=2, C=3......)

2. After converting we will multiply each number by 2

3. Spaces will be a special symbol

( space=/)

Step by step example

"I" → 9 → 9 × 3 = 27
"F" → 6 → 6 × 3 = 18

So "IF" = 27 18

The coded message

27 18 / 27 / 69 15 54 45 / 3 / 21 45 45 57 15 / 27 / 69 45 63 36 12 / 36 3 75 / 21 45 108 /.

To decode divide each number by 3

When the number is less than 1, the square root is larger than the original number.

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199.

Number Divisors

60 12 divisors

72 12 divisors

84 12 divisors

90 12 divisors

105 12 divisors (odd)

From this, we can observe that while even numbers like 60, 72, 84, and 90 have the most divisors under 100, the odd number 105 also has the same number of divisors (12).

1km=1000m

1m=100cm

1000m=100000cm

100000/40=2500(strides)

So, I will take 2500 strides to walk along a square having 1km in perimeter

1. Take birthday month (example: 1)

2. Multiply by 7 (1 x 7 = 7)

3. Subtract 1 (7 - 1 = 6)

4. Multiply by 13 (6 x 13 = 78)

5. Add Birthday (78 + 31 = 109)

6. Add 3 (109 + 3 = 112)

7. Multiply by 11 (112 x 11 = 1232)

8. Subtract birth month (1232 -1 = 1231)

9. Subtract birth day (1231 - 31 = 1200)

10. Divide by 10 (1200 / 10 = 120)

11. Add 11 (120 + 11 = 131)

12. Divide by 100 (131 / 100 = 1.31)

Before decimal = birth month

After decimal = birth day

The square roots become bigger than the number for the numbers smaller than 1.

2. Looks nice – Circles are neat and look good on the wall or ceiling.

3. Easy to make – It’s simple to make round light bulbs.

4. Works well – Round lights shine better in a room because the shape matches how light naturally spreads.

The smallest odd number with 12 factors is 315.

^ = l

1.Choose any multiple of 4 below 70

2.Use 3 operations of whole numbers of your choice in any order you like with the number 2 

(eg. 4x2+2-2=8）

3.If your answer is twice the number you started with or more, you earn 1 point.

Rules:

1.You only get 2 tries to get the answer.

2.Once you use a number, that same number cannot be used again.

3.Once you get 10 points, you can get yourself a prize of your choice.

The bowl is in circular shape because it can promote better circulation of heat and a rubriks cube is in a square because it is better to be turned

For number smaller than one , the square root is greater

The square root of numbers bigger than 1 is smaller than the original number.

Some examples are:

√9=3

√16=4

√25=5

I realised that the square root of the number is the product of two same numbers

E.g. 3×3=9 therefore 3 is the square root of 9

The square root of numbers smaller than 1 is bigger than the original number

Some examples are:

(Rounded up to three decimal place)

√0.5≈0.707

√0.25=0.5

√0.1≈0.316

I created a game.

The rules:

1) If your the one chosen to pick a card, pick a card (The cards have numbers on them).

2) As the other players (consisting of 4 other players and 1 chosen one), do not see the chosen one's card

3) The chosen one must construct a problem sum consisting of only addition for the players to solve (The answer must be the number on your card)

4) The players try to solve the problem sum and the player who guesses it first is the winner.

5) Have fun.

What I am using :

I am using a species of rhinoceros beetle which is native in Singapore,it is under the genus Chalcosoma which means (bronze body) in Latin . It’s scientific name is Chalcosoma Caucasus Kirby but was later known as Chalcosoma Chiron Kirby

Why I think there is these shapes : I think there are these shapes as th thorax represents a circle and the abdomen represents a rectangle .There is also an additional triangle as it celiphic horn . So basically, it is made out of shapes!

E.g.Can you make the number 54 using the numbers 5,4,6,8,8 and 2?

How to play:

Choose any multiple below 5 and make a equation out of it with all +, -, x and ÷ symbols (e.g. 8+4-9÷x2)

Choose a player to answer your equation and if they get it wrong, they are out of the game for one round.

Triangle : multiples of 3

Rectangle : multiples of 2

Prism : Tolberone Chocolate and house roofs

Pyramid : Camping tents and pyramid like collectables

The average temperature of the day was around 36.6°c

Diameter (D): 7.00cm
Circumference (C): 21.99cm (to 2dp)
Quotient (c/d): 3.14 (to 2dp)

Circle B:
Diameter (D): 3.50cm 
Circumference (C): 11.00cm (to 2dp)
Quotient (c/d): 3.14 (to 2dp)

Circle C:
Diameter (D): 8.70cm
Circumference (C): 27.33cm (to 2dp)
Quotient (c/d): 3.14 (to 2dp)

Circle D:
Diameter (D): 13.3cm
Circumference (C): 41.78cm (to 2dp)
Quotient (c/d): 3.14 (to 2dp)

Conclusion:
The quotient c/d always equals to 3.14, as when dividing the circumference by the diameter the resulting value will always be equal to pi which when rounded off to 2dp is 3.14.

Operation Race

Goal: Reach exactly 100 first.

Rules:

Start at 0.

Players alternate turns.

On your turn, apply one operation (+, –, ×, ÷) with a whole number 1–10 to the current number.

The result must be a whole number between 0 and 100. If not, skip your turn.

First to reach 100 wins.

If no one reaches 100 in 20 turns, closest number wins.
