Multiplying by 6
Multiplying by 6 is counting by 6 and knowing where to stop:
6 = 6 x 1 = 6
12 = 6 x 2 = 6 + 6
18 = 6 x 3 = 12 + 6
24 = 6 x 4 = 18 + 6
30 = 6 x 5 = 24 + 6
36 = 6 x 6 = 30 + 6
42 = 6 x 7 = 36 + 6
48 = 6 x 8 = 42 + 6
54 = 6 x 9 = 48 + 6
60 = 6 x 10 = 54 + 6
And here is your multiplication table:
Science 🔬
Earth
Today we will talk about Earth – our home planet! It’s the 3rd planet from the Sun. Like our two previous planets, it’s terrestrial, meaning it has a rocky surface. Unlike Mercury, but like Venus, it has an atmosphere. Ours is made up of nitrogen and oxygen. Earth has one moon, but that’s a story for another day.
Relative to Venus and Mercury, Earth has a relatively stable temperature on the surface. This is in part because 71% of the surface of our planet is covered by water. Water keeps heat pretty well, but doesn’t trap too much of it causing global warming (also a story for another day).
It takes Earth 23 hours and 53 minutes to spin once around its own axis. That’s how long our actual day is. I bet you thought it was the round 24 hours, didn’t you? Our year is 365.3 days long – that’s how long it takes us to travel all the way around the Sun once. You know how we have 365 days in a year? But this year, we have a ‘leap year’, where February had 29 days, making 2020 have 366 days. That’s to fix the additional hours in every year.

Ancient Greece – science
Greeks were great scientists! They made huge progress in science that we use every day:
Math – some great mathematicians lived in Ancient Greece, including Pythagoras, Euclid and Archimedes. Here are some subjects that Greek mathematicians created:
- Geometry
- Formal proof
- Number theory
- Mathematical analysis
Medicine – they were the first ones to make medicine a separate science from others and Hippocrates is considered father of modern medicine.
Astronomy – they were very good at observing the sky. They created a model of the Solar System (I wonder if theirs looked like the one I have been working on?) and charts of the stars in the sky. They were the first ones to figure out that Earth was spinning around its axis and that planets traveled around the Sun.
Trivia ❓
In Greek mythology, Prometheus stole fire from the gods and gave it to humans.
Word of the Day ❗
