Maths

Today’s maths session is the 11 and 12 times tables. At the end of Year 4, it is important that we are secure in our times tables. There is a video, worksheet and answer sheet for the session. Please make sure you watch the video before your worksheet as it explains the session really well. You will also be prompted to have a go at certain questions from the sheet that link in with the video. 

Please see the worksheet below for today’s session. Again, don’t feel too pressured to complete every question on the worksheet. Remember Miss Housley and I are always available to help you.

SPaG

Today’s SPaG session is skill based, looking at how to use inverted commas to punctuate speech in writing. This skill is going to be important to use in tomorrow’s writing for your newspaper!

Please watch the video below where I explain how to use inverted commas and focus on the three rules that I would like you to use on the worksheet attached.

Read the worksheet instructions. I would like you to write the sentences in your books with the correct punctuation added.

The answers will be uploaded in the afternoon so you can mark your work.

Topic

Firstly, let’s check in with what some of our classmates have added to their newspaper articles.  Here is Syd’s effort:

As you can see, he has completed the opening paragraph where he tells us what happened, where and when.  He has also completed paragraph 2.  In this paragraph, he has used his topic knowledge from Monday by telling the newspaper readers what a tsunami is and how it is caused.  Finally, paragraph 3 is very short, it just tells us how our particular tsunami was caused.

Topic – stages of a tsunami.

So far this week you have found out what a tsunami is and what causes a tsunami.

This afternoon, we are going to look at the stages of a tsunami and some key vocabulary.

Seabed: This is the bottom of the ocean, you may have heard of this as the ocean floor or sea floor before.

Epicentre: This is the main point of the Earth’s surface directly above where the earthquake or underwater explosion occurred.

Most tsunamis are caused by earthquakes under water. In this example, an oceanic plate is subducted (this is where the plate is moved down into the Earth’s mantle). This movement causes friction and the plates get stuck. When the plates get stuck lots of energy is produced and this moves the plates back into position. As the plates move back into position (they move up, you can see this in the plate movement on the diagram) this forms a wave.

The waves can travel large distances. When the waves reach the shallower water this is when the damage is caused!

  • the shallow water slows the waves
  • the height of the waves can increase by several metres
  • the waves get closer together

In this diagram, you can see the large waves move along the seabed. The Earth’s gravity pulls the wave back down and this is how the waves rush towards the land and destroy anything in its path!

As the water rushes towards land, the waves increase in height and break. This is where the tsunami destroys anything in its path!

Topic task – we would like you to tell us the stages of a tsunami. 

You could do this by a labelled diagram (drawing a tsunami and labelling the different stages) OR some of you may like to dress up in a long white t-shirt (not your mum’s dress, Clarke!) and record yourself talking about the stages of a tsunami, please email it to us! 

The labelled diagrams below may help you if you decide to do one!
