Mathsmate: Term 3, Sheet 2

Problem 22: Carl looked at the page numbers on the open book in front of him. The left and right page numbers added to 333. What were the page numbers?

Predict: I predict I will need to use division and addition in this problem.

Clarify:  I have no words, sentences or phrases to clarify.

Find the big question: What are the page numbers?

Solve:

  1. I need to start by splitting 333 in half, because they need to be consecutive. Picture a book, the page numbers are consecutive,, aren’t they?
  2. It is 166.5 but I will round that up to 167.
  3. 167+168=335.
  4. So I will round down to 166.
  5. 166+167=333!

Summary:

The mathematicians toolbox strategy I used in this problem was break it into manageable parts.

When I sprinted up to the ice cream stand and I ordered a banana-swirl ice pop. But ‘I’m afraid it’s the last one’, he said. “OK, I’ll get… a… um… strawberry please.”

Ahhh… that all seems like such a long time ago now. Even though it was only 29 hours ago. But now I live in a hut of leaves, you can’t expect me not to remember. I wish I appreciated everything more. Now I have nothing, except for this pen. I’m writing on a piece of bark, for goodness sake.

“Gosh, nobody has anything anymore!”

Problem 22: The sum of two consecutive whole numbers is 97. What are the two numbers?

Predict: I predict that I will need to use division adn addition in this problem.

Clarify: I have no words, sentences or phrases to clarify.

Find the big question: What are the two numbers?

Solution:

  1. The first thing I did was divide 97 by 2= 48.5
  2. but they are consecutive whole numbers. 
  3. So I rounded up to 49. But 49+50=99, not 97.
  4. So I rounded down to 48. 48+49=97!

The answer is 97.

Summary: The mathematicians toolbox strategy I used is this problem was work backwards.

100 WC #32

As I wandered through the streets of the city the people chatted to me like I was an old friend. They were kind, but they were creepy and scary. They were old and shrivelled in the markets but young and silly at the  sea-side. They spoke to me, a lot. Some of the words sounded like a foreign language. But they were, anyway. When I turned a corner I walked back into my hotel, and upstairs into my bedroom.

I heard a knock. It was 1:42 am! Seriously, at this time of night? I opened the door. “Siiahhhhhshiiiiiiickkeeeeeeshhhhhhckiiiiii…..”

“AAAAAHHHHHHHH!”

100 WC Week #38

“Aaarrrggghh…” I groaned. This could have been the perfect day. A picnic and a tent set up, right in our backyard, the perfect food and drink for everyone. But it was far too hot for everybody. Most of our friends had already left by now. It was a scorching 47 degree day and I could barely lift my body off the ground. Nobody could. But as the afternoon slowly progresseed on it got coocler and cooler had people actually started moving and talking.  We had Sport tommorow at school and I really didn’t evern want to go out for lunch letalone cross country practice. Uggghhh.

100 WC Week #37

I sat down on the couch, drink and pop corn in hand. Well, I thought. This is nice.

But that’s not whats happening in Brazil. They are all filing into the big stadium ready to play. The soccer nets are up. The scoreboards are on. The crowd is wild. The coach is psyched.  But that’s what’s happening in Brazil when the whistle blows.

The crowd erupts! The coaches go off! The commentators roar! I scream at the TV! ‘GO! KICK IT IN!” I’m not the only one. I can literally hear the words through my home cinema speakers. Well, it’s not really a home cinema. Just a TV room.

So that’s what’s happening in Brazil.

Problem 23: if you could roll the same number every time, what number would you choowe so that you could move from S to F in the least number of rolls.

Predict: I predict that this problem will take a lot of trial and error.

Clarify: I have no words, sentences or phrases to clarify.

Find the big question: What number would get me to the finish in the least amount of rolls?

Solution:

In this problem I am just going to test out each Number and how many rolls it will take. For each number I wrote it down, but I remembered to keep in mind the snakes and ladders!

Theses are my results:

1- infinite

2- five rolls

3- infinite

4- infinite

5- infinite

6-  infinite.

The answer is 2.

Summary: the mathematicians toolbox strategy I used in this problem was trial and error, and make a list.

100 WC Week #36

Today is easter! I love easter! I love chocolate more than anything. Anyway, I grabbed my basket and my brother and I set of for the hunt. Yes! I found the first egg! I immediately unwrap my egg. MMMMM! Peppermint! “Ugghh!” I moaned. My egg! It fell! As I leant down to retrieve it, I noticed some tiny orange ants crawling onto it. Those aren’t ants. They are little people! What!? As I looked closer, they were wearing little vests, and they had set up cones all around the egg. The started to investigate, as I felt my legs and arms lift off the ground…

What?!”

Problem 23: Jack’s car can travel 15 kilometres per litre of petrol. He leaves Dubbo with 30 litres of petrol in his car and drives towards Maitland. Which town will he be closest to when he runs out of petrol?

Dubbo——-200 km———Wellington—-100 km—Mudgee—-150 km——Singleton——-200 km———-Maitland.

Predict: I Predict that I will need to use multiplication in this problem.

Clarify: I have no words, sentences or phrases to clarify.

Find the big question: Which town will he be closest to when he runs out of petrol?

Solution:

  1. First we need to find out how many kilonmetres he can travel on 30 litres of petrol.
  2. So we need to multiply 30 by 15: which equals 450.
  3. So he can travel 450 km on 30 litres of petrol.
  4. So, on the map, from Dubbo, add on 450 km.

+                     =300              +                   =450. 

Dubbo——-200 km———Wellington—-100 km—Mudgee—-150 km——Singleton——-200 km———-Maitland.

The answer is Singleton.

Summary: the Mathematicians Toolbox strategy I used in this sum was break the problem into managable parts.

I’m running. I’m running as fast as I can. The gateway is approaching rapidly. “I’m coming, my friend….” Says the voice. The air turns cold. The cemetery turns black. The gates are closing. Closing…closing…closing…..

I’m panting. I’m panting as hard as I can. The gates have closed. The voice is close. My life is far, far, far, long, long, long gone….

I’m crying. I’m crying as hard as I can. My mind is closed. The voice is mine. The voice is is in me. In my body. His mind is mine. My body is possesed…

Goodbye. Goodbye, my life…
