Symmetry

Leave a comment

We have been learning about symmetry in maths this week.

We have been learning about line or reflective symmetry.  Line symmetry means a reflection.  If we were to draw a line through a shape to represent a mirror, the shape could be folded on that line and both sides would fit together exactly together.

After looking at lots of examples on the interactive whiteboard and playing some games on Education City, we sorted these pictures in our maths books.

This afternoon we had the choice of two activities when using the computer. One choice was to draw a horizontal or vertical symmetrical picture using Pixie.

The second choice was the most popular! We created snowflakes using this website. Try it for yourself. Did you know that real snowflakes are always symmetrical and have their own amazing patterns?

Here are some we made.

We also found this site to make a cut paper snowflake online. Have fun making your own symmetrical snowflakes.

2D and 3D shape

Leave a comment

We have been learning all about shapes and their properties since we came back from the Easter break. Here are some of the activities we have been doing.

We went for a “shape” walk to look for 2D shapes around our school.

We are showing how many sides our octagonal tables have!

We worked together to complete tree diagams for the properties of 2D shapes.

We made lift the flap books about 3D shapes.

We learned about nets and made our own 3D shapes from nets.

Our favourite activity was this one – making 3D shapes from cocktail sticks and marshmallows!

Mrs Stewart joined in.

Measurement

Leave a comment

Today we continued some of our work on measurement. We are learning to understand and use the vocabulary related to length and use comparison to compare lengths.

We made plasticene snakes that were about 10 or 20 beads long on a bead string. We compared these to a photocopy of a beadstring.

After that, we had to measure some pictures of snakes and say how many beads long they would be. This was quite tricky as the snakes were curled up. we discussed how we could go about this. We decided we could use string to measure the snakes and then compare it against the bead string.

However, the string was quite hard to use so we deceided to go back to using the plasticene! This was much easier.

Superstars, I have added some measuring activities to our maths folder TES i-board that you can try at home. Click here.

Little Red Riding Hood Maths

Leave a comment

We have been learning about position in maths and language.

We found out that the position of something tells you where it is. We worked together to make a list of position words such as over, in, above, below etc.

Mrs Stewart told us that these words are also called prepositions.

We worked in groups of four to illustrate our understanding of these words.

We each had a character from Little Red Riding Hood. We each made a separate poster in our group of four. We made a collage or drew a picture and added a sentence with a position word. Then we put all four posters together to make one big poster. We attached our fairytale character to the middle by a piece of ribbon. This meant that we could move our character to the place indicated in the poster.

Have a look at some of our work

We are now making Red Riding Hood themed Bee Bot mats. We will post some more pictures once we have finished.

Ten Flashing Fireflies

Leave a comment

In maths, we have been learning to solve addition and subtraction story problems using pictures and manipulatives and then an equation. We have learned that the word “equation” is another name for a sum or number sentence.

Yesterday, we read a book called “Ten Flashing Fireflies.”

The cards on the left are part-part whole cards. We look at the number on one side and we have to work out what the number is on the other side that makes up the whole number at the top.

First, we warmed up our brains by doing some subitising. Subitising is being able to see how many things there are in a small collection without counting by ones. We used some dot cards.

In the book the children catch fireflies and put them in a jar.

As Mrs Stewart read the story, Frazer moved the fireflies into the jar using the interactive whiteboard.

We discussed what equations we could write that represented the pages in the story.

We then had our own firefly story problems to solve.

We had problems for numbers within 20 and some up to 100 if we wanted a challenge. Most Superstars chose challenge questions!!

We used our think mats to solve the equations.

What a busy morning!

Mr Wolf and the Three Bears

2 Comments

During the week we read another of Mrs Stewart’s favourite books, “Mr Wolf and the Three Bears” by Jan Fearnley.

In this book, Mr Wolf invites the three Bear’s over for a party to celebrate Baby Bear’s birthday. But guess who turns up to spoil the party? Yes, that’s right, Goldilocks!!

Never mind, she gets her comeuppance in the end. Read the book and you will find out.

In the book, Mr Wolf and Grandma Wolf look on the internet, at a site called www.hungry-wolf.com to get some ideas for recipes.

We decided to try out two of them – Cheesy Snip Snaps and Daddy Bear’s Huff Puffs.

Cheesy Snip Snaps
Daddy Bear's Huff Puffs
Delicious!

We also did some porridge bowl art. It was a busy day!

Jack and the Beanstalk Maths

Leave a comment

As well as our Dragon challenge, we have been doing lots of other Jack and the Beanstalk related measuring activities this week.

We estimated how many of the Giant’s boots it would take to cross from one side of the gym to the other. Then we went into the gym to find the actual answer. We had to remember to line up the boots heel to toe and not to leave any spaces.

We used our Giant’s boots to find things that were longer, smaller or the same size. We drew and labelled the things we found in our special books. We visited the nursery in groups to measure things in there.

After that, we made beanstalk pictures with beanstalks that were longer, shorter or the same size as the boot.

On Friday, we used special “bean” rulers to measure things around the class. The rulers were only 10 “beans” long so we used two for things that were a wee bit longer.

Dragon Maths Challenge – Estimation

Leave a comment
What could this be?

On Wednesday, we were all very excited to find the Dragon had left us another letter and a present!

In his letter, the dragon told us that he had heard that we are learning about measurement in maths, and that he wanted to set us a challenge.

He sent us some sheets of paper with an outline of the Giant’s hand. In the bags were magic beans.

First, we had to ESTIMATE how many beans would fit on the Giant’s palm (we knew from our Halloween maths that an estimate is a sensible guess). We had to write down our estimates in pen so we could not change them later!

Then we arranged our magic beans on the Giant’s palm to find out the actual number. Finally, we worked out the difference between our estimates and the actual number, using our calculators.

After that, we drew the outline of our own hand on the Giant’s and did the same again, only for our hand this time.

We really enjoyed the Dragon’s challenge and hope he will send us some more.
