Today is Day 47 of our stay-at-home time.
Keep reading to learn some cool facts about the number zero (0), how to draw mandala circle art and how to cut a BIG circle from a paper rectangle.
COOL FACTS ABOUT ZERO
Here are some cool facts about zero (0):
- Zero was invented by Brahmagupta (a Hindu astronomer and mathematician) in 628 AD in India and used later by the Persians and Arabs and later in Europe.
- Leonardo Fibonacci brought zero and the Hindu-Arabic (our modern number system) to Italy and Europe over 400 years ago.
- Zero is an even number.
- The word zero comes from the Arabic word "sifr" which means "empty".
- In the game of tennis, a score of zero is called “love”.

MANDALA CIRCLE ART
Mandalas are circle shaped designs. The word "mandala" comes from the ancient Indian Sanskrit word for disk or circle. Many people think that drawing mandala designs helps to lower stress and make them feel calm.
These are some of the mandala designs that I drew in my drawing journal. You start with a circle in the middle and draw lines and shapes all around the outside. It shows a type of symmetry called radial symmetry (lines of symmetry that come from the centre of a circle). It's a lot of fun!
Here is a video that will help you start:
If you draw some mandalas, take a photo and email it to me. I really like seeing your work!
THE SUPER CIRCLE PAPER TRICK
In this trick, you take a paper rectangle, cut it and create a paper circle big enough to walk through! Really!
You will need a regular sheet of paper, a pencil, a ruler and a pair of scissors.
1. First, fold the paper in half, short edge of the rectangle to the opposite short edge of the rectangle.
2. Next, draw 7 vertical lines evenly spaced across, starting at the bottom folded edge but ending about 1 cm from the top edge.
3. Then, draw 6 vertical lines evenly spaced across AND in between the first set of vertical lines, starting top edge but ending about 1 cm from the bottom folded edge.
4. Now, cut the six places along the folded edge (see photo). DO NOT cut the one on the far left or the one on the far right.
5. Finally, open up your SUPER BIG circle! Can you walk through it? If it doesn't work the first time, try again!
Iggy is always a good helper! If you try this, take a photo and email it to me. I really enjoy seeing your work!
