Analyse

USA is the richest and Korea is the poorest. The different between USA and Korea is $16810. Spain Italy and Greece are almost the same in wealth. This graph is the right kind of graph because you use a bar graph for categorical data and are large amounts and our data it both of those things.

maths reflection

December2

I chose break the problem into manageable parts but when I started solving it I used test all possibilities. I think I can reflect on the lesson any lesson  better now I have had it explained it me more deeply. I learnt how to go more deeply into the problem that I was solving.

MATHEMATICIANS TOOLBOX

February19

 

The Mathematicians toolbox has 12 strategies. They are:

.Break problem into manageable parts.

.Make a model.

.Act it out.

.Make a table or list.

.Guess check and improve.

.Have I seen a problem?

.Test all possibilities.

.Find an exception to the rule.

.Look for and describe with a pattern or rule.

.Write a sum or number sentence.

.Draw a diagram or graph.

.Work backwards.

They are the 12 strategies.

Draw a diagram or graph is when you have data you can draw a graph to find which is the most or when you have a problem you can draw a picture but if it was something that would be long just draw little circles but not to small.
