Two Problem Tuesday

Team up Tuesday

Thinking of a Number

A quick brain teaser to get you started. It will be interesting to see what sort of strategy you come up with to solve this problem.
Read thoughtfully.
Use Explain Everything and write down your thinking so we can see how you found the number we are looking for.
I wonder if there is more than one way to solve this problem?



$100 Word Challenge

Each letter of the alphabet has a dollar value which is the same as it's place in the order of the alphabet. (A = $1, B = $2............ Z = $26)

Before you begin your thinking for this challenge, have a quick think and write down the names of two class mates.
Estimate quickly. The idea is to get the team of three with the highest value?

1. What is your full name worth? ( Colin Isherwood = $169) 
2. Find a hundred dollar word?

Show al your working out so we can check each others calculations and so we can share strategies for adding quickly and accurately.

Circles (The most important shape?)

Wow! I thought a circle was just a 2D shape.

Watch and learn. 

Remember we work in millimetres, centimetres and metres not feet and inches.

Now I have some questions my self, time to do some thinking and learning.

Written Conversation

1. Use one of these pictures. Make speech bubbles for them and write in what you think they might be saying.
2. For the other picture write a little story based on what you think is happening in the picture and as part of that short story share a conversation that the two people might be having as part of that story.

Here is a link that might help you understand how this punctuation works.

Descriptive Writing

Dividing a circle into equal sectors

Another drawing challenge. This one involves a bit of maths and we are then going to use this skill to build cogs to create a class machine.

Multiplying Decimals

A quick bit of research now that we have struggled with a problem and I find out that multiplying decimals is not as hard as we thought.

How to make a Pantograph

Only visual instructions for this task. We will make it with thin card and then when we have sorted out all the problems and get it working successfully we will make it with thicker card.
