# Learning Tasks – 24th April

Good morning Year 2.

## Maths

Something a bit different today to help you practise using your adding.

• Think of a number…
• add 10 to your number…
• now add 4…
• …subtract 5…
• …then subtract 9..
• Are you back at your start number?

Why does this work? Can you come up with your own ‘Think of a number’ problem to try out on someone else. Remember, you can use the skills from earlier in the week to help you solve and make these sorts of problems.

If you have time, below is a more complex version using double and half.

What do you notice this time?

To understand why this works imagine the blue line in the picture is a 10 and the orange dots are 1s.

## General

This is a science activity you might want to try over the weekend.

Amber is tree sap that has become as hard as rock. Sometimes small insects get fossilized into this sap.

I would like you to have a go seeing if you can create your own fossilized creature. To do this you are going to need to place a small object into an ice cube. If you google hatching frozen dinosaur eggs there are some good suggestions on how to do this using balloons. Alternative placing something small into an ice cube tray will work just as well.

Then, once you have created your ‘amber’ user your science skills to see how quickly you can release the creature OR how long you can keep it fossilized. Things to think about:

• Just breaking open the amber could damage the fossil so think of another method.
• What materials that keep things hot/cold could you use
• What could you use to record how long the creature stays in the amber
• If you do the experiment more than once, how will you keep it fair each time.

## Writing

We have been thinking about Mary Anning a lot this week. We have learnt how she collected and studied fossils from near her home of Lyme Regis.

Today I am interested in any collections you have. I know some of you have already collected fossils and that others collect things like football cards. Why do you collect them? How many do you have? What is your favourite/best/rarest? What are you looking/hoping to add to your collection? If you don’t have any collections already, what would you collect?

In your work today, I would like you to try and extend your sentences. Try to use prepositions (location words) to explain more about the collection (what do the cards have on them, where did you find the rock). You can also extend them using the words that, which and at.

Over the weekend, you could write about your collection or produce it as video (you may still need to write your ideas down so you remember what to say). If you send them to me, next week I will try to turn some of them into a reading activity to help us learn more about each other.

`My name is Mr Salmon and when I was younger I had a collection of different rocks. My father studied rocks at university. He would tell me about the rocks we found when we went walking on holiday. I would bring some of them home with me.I had rocks that were smooth and rocks that were very rough. The smooth rocks came from under the water at a beach. They had white lines going across them that glittered when the light shined on them. My favourite rock was called iron pyrites which looks like gold. I found it on a school trip. It had little golden cubes around the edges...`
