Angles

It was a few weeks ago now - but can you still remember the work we did on angles?

Click here to play a game where you guess the number of degrees in an acute or obtuse angle. You might like to hide the protractor to make it more tricky!

Angles & LOGO

For all those pupils who still want to practise their ICT and Maths here are some interesting LOGO commands for you to try.

Well done this week, you drew really precise angles in your Maths books and followed it up with some fantastic LOGO programming!

6 x 7 = ?

Don't forget to practise those multiplication facts!

Here is a webpage that will help you.

Problem Solving

Today (the 8th/9th) we were trying to solve leapfrog, it was so much fun doing it! We eventually worked out that 2x2 = 8 moves, 3x3 = 15 moves, 4x4 = 24 moves, 5x5 = 35 moves, 6x6 = 48 moves and 10 x10 = 120 moves (which was the whole class!)

Then we looked for patterns and recorded them (like the picture above.) 3 x 3 was very hard for some people. (The picture is 2 x 2)

LOGO

Today in Maths we are using LOGO to draw polygons! Accuracy is the key, one little mistake and you will be scratching your heads.

The picture above was created by defining a circle. First type:
to circle
repeat 360[fd 1 rt 1]

Now type in circle to test your instructions. Did the circle draw okay?

Next, use the circle to draw a repeating pattern by entering these instructions:

to sunflower
circle
pu
rt 321
pd
sunflower
end

These just happen to be the instructions we tested this afternoon - what we were really interested in was creating regular polygons, but we couldn't resist repeating them to make interesting patterns! We might make Christmas decorations...

Please ask for permission before installing LOGO at home!

Mr Short

Keywords:
pu - pen up
pd - pen down
fd - forward
rt - right turn
lt - left turn
repeat
end

You can also change the background colour and the colour of the pen! Try going to the help menu and clicking on demo - LOGO can produce some tricky designs.

Maths Mentos Millilitre Challenge!

Each day last week Class 5 were really involved in their Maths. On Friday we added Science & ICT into the mix. We hope you enjoy it as much as we did!

At the start of the video there is a brilliant picture of a Cola fountain (one of many taken by a pupil using a digital camera). The child in question earned a camera licence by recording our lesson and will now pass skills, tips and a licence to his classmates.

I feel that this ownership of ICT represents a more realistic use of technology and helps the children recognise how ICT can support their learning. With the availability of extra laptops Year 4 are already regularly ticking ICT objectives in the new term as well as maintaining some old ones!

Using digital cameras to record our work

Good timing, skill, patience or luck? Perhaps all four, but you have to agree that this picture taken by a pupil in Class 5 is excellent and I couldn't do better myself. It was part of Class 5's maths & science investigation last week...more to follow soon!

This dictionary helped us today

It might help your class also!

Class 5 measure up

On Wednesday we made our own scales in maths. We used 2l plastic bottles and filled them up 100ml at a time. We used permanent pens to mark all the numbers so if we got it wrong we would have to start again. We had 3 buckets of water and we split into 3 groups (we did this outside!). Here is a picture.
