Regrouping

Today’s lesson is about regrouping when you do two-digit subtraction. This is when you subtract one number from another and you have bigger digit in the first number than in the other. Let’s use an example to help me explain. We will be figuring out how much 41 – 18 is.

First, write them down like this:

4 1

-1 8

Make sure that the first number is on top – order of numbers matters when you subtract!

First, you need to subtract numbers on the far right side. But oh-oh! 1 is larger than 8. Now what 🤔

Now you’re going to go in the front and cross off the 4 and make it a 3. Go into the last number and make it 11:

3 11

4 1

-1 8

Now you subtract 8 from 11 and that works – it’s 3:

3 11

4 1

-1 8

3

Now all you have to do is subtract 1 from 3, which is 2:

3 11

4 1

-1 8

2 3

Volcano

Volcanoes are mountains with lava inside. Majority of volcanoes on Earth are not active. Being active means when the lava comes out of them. There are other things that come out of volcanoes during an eruption: steam, gasses, ash and pieces of rock. Lava can flow out of the top or the sides.

There are two types of volcanoes:

Shield volcanoes – lava usually flows out of them without big explosions, causing it to create layers of rocks made of cooled down lava. They are usually wide and their sides aren’t steep. An example of a shield volcano is Mauna Kea in Hawaii.

Stratavolcanoes – these are steep mountains made of hardened lava. They sometimes erupt, but you can’t really tell when and it can be a very long time between eruptions. The most famous stratavolcanoes are Mount Fuji in Japan and Vesuvius in Italy.

Queen Elizabeth I

Queen Elizabeth I was born on September 7, 1533. Her parents were King Henry VIII and Anne Boleyn. She had an older half-sister named Mary and a younger half-brother named Edward. After King Henry VIII died, Edward became king, but he didn’t rule long. Since he didn’t have children, his sister was supposed to become queen. Unfortunately, there was a fight over which one: Elizabeth or Mary. Elizabeth won. She never got married and did not have children. She died March 24, 1603.

Queen Elizabeth’s accomplishments:

• She made Protestant religion England’s official religion
• When she was the queen, a lot of artists worked in England. William Shakespeare wrote his plays. There were many other writers, poets and composers there, too
• She paid for many trips across the Atlantic Ocean, which led to colonization of America

Activity of the day 🏛

Watch me create a volcano explosion at home:

To create your own volcano explosion, you can use some items from around the house. Here is how to make the exploding lava:

• Put water in a bottle and add some food dye (red, possibly orange or yellow)
• Add 6 drops of laundry detergent
• Add 2 tablespoons of baking soda
