Let's Investigate Triangles

Vincent and Tara are making triangles with the class construction set. They have a pile of strips of different lengths. How many different triangles can they make?

If the World Were a Village

Stage: 1 and 2 Challenge Level: Challenge Level:1

It was good to read your responses to the question of data representation.

We have chosen six solutions, each sent in from a different country - very fitting for this problem. 

From Vincent & Salambô at Lycée Henri Matisse in France we had:

For the first question about the population of the village, we choose the drawing with the heads organised in a square rather than the drawing with the head scrambled. Because in a square of side $10$ we understand easily that the area is $100$. Thus to symbolise $100$ people the best is to draw a square of side $10$ little heads.

From St. Martin's Gully School, Australia Ben wrote:

In the first graph with the people, I think the first one is best because its meaning is easiest to decipher. In the one with flags, I think the second graph is clearest because it is not as messy as the first one.

From Dubai in UAE we had a response from Amatuliah at Alameen Private School who wrote that for question $1$ the first way was best and for question $2$ the third one was best.

Jenson from Middleton Tyas Church Of England Primary School sent in a Word Document which shows his work very clearly - well done!  You can view it here.doc  or  here .pdf.

Marcus from Peak School in Hong Kong wrote:

We can show the data with tally marks, bar charts and words.

I don’t think pictograms are always the same.  I think words are better because maybe the person who is looking at it might not know what the pictogram means unless there is a key for the pictures’ representations.

Pictograms are good to a certain extent if there are keys showing differences of the data and if there are organised systematically.

Fiene part of the Homeschooling Science Club in the Netherlands sent in the following:

Our homeschooling Science Club of nine children worked in groups to make posters for:
1. how many people in the village have a telephone
2. how many people in the village have electricity
3. how many people in the village have clean water at home or nearby

What do you think? 

Well done everyone it's so interesting to see all the different approaches you've used.
