Today is another set of exercises for your legs:
Multiplying by 3
Learning how to multiply by 3 is all about memorizing the numbers. Here they are:
So you are basically counting by 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 or:
3 = 3 x 1
6 = 3 x 2 = 3 + 3
9 = 3 x 3 = 6 + 3
12 = 3 x 4 = 9 + 3
15 = 3 x 5 = 12 + 3
18 = 3 x 6 = 15 + 3
21 = 3 x 7 = 18 + 3
24 = 3 x 8 = 21 + 3
27 = 3 x 9 = 24 + 3
30 = 3 x 10 = 27 + 3
We thought that watching a video showing the multiplication may help:
For now, keep repeating multiplying by 0, 1, 2 and 3. We will get back to math exercises on Friday!
The Sun is the star at the center of our solar system (we will talk more about what solar systems are once we go through all the planets) – this means that planets go around it.
The Sun is a dwarf star and has the mass of 333 thousand Earths, while its diameter is 109 times larger than that of our planet. It’s located 93 million miles away from us and that distance is used in astronomy as a measurement unit called Astronomical Unit (au).
The Sun is made of two lightest elements: helium and hydrogen. In the center of our star, gravity is so strong that hydrogen is squeezed so tightly that it transforms into helium in the process called nuclear fusion. That’s what makes the Sun glow. This energy travels to Earth in form of light. All living beings (animals and plants) use it as a source of energy, which allows us to grow and survive. But more on that in the future.
The Sun wasn’t hard to discover for humans – we can see it every day (well, unless it’s cloudy 😉). In the ancient times, it was actually worshiped as a god. Do you remember the name of Egyptian god of the Sun?

Ancient Greece – history
Ancient Greece developed on the Peloponnese Peninsula and surrounding islands in the Mediterranean Sea. Currently, that’s where country of Greece is located. Ancient Greece wasn’t really a unified country, it was a number of city-states (that’s like a country) called polis that shared similar culture. The land there is rocky and not great for farming. Ancient Greeks focused more on herding animals and trade. They built many ships and sailing was important to the culture and economy.
History of Ancient Greece has three periods:
Archaic – this is when culture in Greece started to develop, beginning around year 800 BC. The small city-states had their own kings. It actually ended in year 508 BC, when Athens became a democracy.
Classical – historical period that we all think about the most when we talk about Ancient Greece was defined by polis being ran as democracies. They all came together during large wars. The first one was against Persia, which made Greek city-states work together and think of themselves as Greeks. The next one was between largest cities: Athens and Sparta, dividing the country between the two. Athens were focused on culture and science, while Sparta was all about war. This period ended with the death of Alexander the Great. He was king Macedonia. He unified much of Greece and conquered a lot of Europe and Western Asia, including Persia and Egypt.
Hellenistic – during this period, Roman culture was developing and their country was growing in power, while Greece was becoming weaker. Fall of Egypt to Rome is considered to be the ending of Ancient Greece.
Amphibians are species which can live on both water and land.
