Zoo Maths - thanks to Mrs Madden!

Hippo Maths - October 2016

Photographer William Warby snapped these 2 kissing hippos at the Whipsnade Zoo in England. Actually, it's hard to tell whether they're playing, kissing, or just shoving each other out of the way. Hippo is short for "hippopotamus,' which means "river horse."

These round, grey lumps are the 3rd largest land mammal, after the elephant and the white rhinoceros. The funny thing is, their closest cousins are another set of chubby mammals: whales and dolphins! Well, hippos love water just like they do, and it looks like they love to play, too.

Questions:

1 : Hippos need to breathe every 3 minutes. If a hippo swims for 3 minutes, comes up for 1 minute, then goes under for 3, how many minutes does that take?  

Bonus: If it keeps up that pattern, is the hippo swimming or breathing at 10 minutes?

 

Extension : A hippo can live until 45 years. If a hippo's grandchildren are all ages that divide neatly into 45, with 1 hippo of each age, at least how many grandchildren must it have?

Pac Man part 3

Wow an end result to 2 days of Maths thinking! If you would like to know what our challenges were take a look at our window and see if you can solve them too!

Now we are going to use our pictures to revise how to estimate, count using arrays, count in 2s, 5s, and measure perimeter and area. 

We are going to draw our own versions on grid paper and make our own mazes. Then we will write instructions using Rotation and Direction words. Watch this space!

Day 2 of Pac Man

This group are reading their challenge before deciding if they need to go out into the school to explore or ask another teacher for clues, or work out the problem themselves.

Measuring time, length, and using clocks and themselves!!

Ali wants to count how many stick it notes it has taken to make Pac Man! Will he count in arrays, groups of 2 or 5 or 1-1? 

Tim has a try too, he estimated first and them started to count. How would you count them up? 

Pac Man Challenge

Focus: to revise Maths Knowledge and Skills from during the year in the context of our School Conmunity! 

Room 20 invited R21 and R16 to participate in our challenge too - check out their windows this week as well!

Children were put into groups of 3 and given a bag of 10 challenges to complete in any order. 

Each challenge was awarded 2 stick it notes when Mrs Trembath had listened to  how the group had solved each challenge, before they were given the go ahead to choose another challenge from their bag.

Science Club

Experimenting with Cornflour and Shaving foam! What kinds of changes do you notice happening?

How does it feel? What has the texture become like? Has the temperature changed? 

What do you see?

Instant snow! It feels like cold bread crumbs! 

How did we make it? 

Using 1/2 or 1/4 or 1/3 cups we measured 3/4 cornflour and 1 cup of shaving foam 

Then we mixed the ingredients together with our hands!!

Tinker Time with the Osmos coding

Coding has now been added to our apps. Lots of discussion and forward thinking is needed to solve these problems. Lateral thinking and perseverance are really important in Room 20!

Look at Joshua and see his feeling of success! 

Using Lego to compare 1/2 fractions for Maths Week!!

What can you see on the Lego? 8 dots what will half of that be - 4/8. What will half of that be 2/8. What will half of that be 1/8. 

We repeated the thinking with 1/6 and 1/4. We are thinking and learning about the whole fraction and the denominator and the numerator. 

Drum Roll Please! Our Stadium is complete! Now to use it!

The secret material has been revealed - Bubble Wrap! To create the Water effect we saw in our study of the Water Cube and to let light into our space, bubble wrap seemed to be the best material - all 30 metres of it! So the maths, technology and group problem solving skills have now been extended this week and we have a new and interesting space to work in.

Inspired by the Beijing Water Cube! Maths and Technology join forces in this Storm of Ideas!

One of the sports stadiums we looked at was the Water Cube in Beijing which was built for the Beijing Olympics Aquatics. We talked about why the Architect chose to design the building like this. What does it remind you of? Water, molecules, ice, bubbles, floating - use your imagination!


So we set about making our own mini stadium using paper, card, sellotape and a secret material to wrap it all up in!

The shape of our stadium was begun with a hexagonal base. Then we had to roll paper to make cylinders. Next we chose the triangular frame shape to hold our wall up as we noticed the beams in our classroom were triangles so we decided they must be the strongest shape.

So here is the frame work all sturdy and strong!

So proud of all the children in Room 20

Children in R20 came to 3 way conferences this week and shared their learning.

 You have all talked, problem solved, drawn, written, played, listened and thought hard this term. I can't wait to find out what we will embark on after the holiday break! 

Here are 4 super members of Team 20

Hamish and Ali for working on maths thinking; Chloe for great expression in drama and reading aloud; Jasmine for a beautifully painted Kea!

Exploring Tinker Time 

Working in a small group to make our own maps: 

A Dietician Mrs Robb visits to talk about sugar!!

Can you read the labels on the sides of the cereal boxes? How many grams of sugar does 100g of cereal have? Can you compare the amount to another box of cereal? Talk about this at home and look inside your cupboard to find out what you are eating. You only need 8- 10 teaspoons of sugar each day so think about that when you are eating your breakfast tomorrow!

Shop Open! Using our place value skills to use money.

This term R20 has opened a shop. Some children are the shop keepers and some are the customers. They have decided how much our items are and labelled them with the price in dollars and cents. When you pay you must work out the money by yourself and if there will be change.

Here Ali is the shopkeeper and Hamish is buying some toy cars! Ali is working the cash register and giving Hamish some change.

This is Jacob stocking up on his groceries. I wonder how much he is going to spend!?

A Rocky 10 Times table

A song to help you get into the Times Tables!

Get those Mighty Mouse Maths Brains going with this video!

Woohoo!

Congratulations Sienna on your maths problem solving this week - perseverance is the key!

Super Book Cover Finalists from our class too! Beautifully drawn book cover designs Chloe C. and Jasmine. Your designs will be on display in the Library.

Literacy Week Begins!

Roald Dahl wrote many children's story books which have been read all over the world. We have been reading George's Marvellous Medicine. Today we made our own "medicine" with the help of Brodie's Mum, Ms Medland and Jessica's Dad, Mr Armstrong. Thank you both for giving Mrs Trembath a hand!

What do you see we have used to make George's Medicine for his Grandma?
