Learning Process & Self Evaluation:

*I have learnt:*	I learnt about which countries had more forests then other countries.
I am good at:	Making the graph.
I need to work more on:	Hyper linking the graph.
My effort for this task has been:	Quality	My best work	Could do better
		ü
Comment: I think I do can better in the hyper linking because I know how to do it now and how to save.

Teacher Evaluation:

Outcome	Progressing Towards	Achieved	Working Beyond
NS3.4 Operates with fractions, decimals, percentages		ü
NS3.2 Selects and applies appropriate strategies for addition with counting numbers of any size		ü
NS3.1 Reads and writes numbers of any size		ü
WMS 3.2 Uses a spreadsheet program to tabulate and graph collected data		ü
Comment: A well designed and easy to read graph. One suggestion is to label the horizontal axis 'regions' as the percentages are shown in your key at the side. Your questions are well thought out. In the second one be specific that you are measuring percentage. A great effort Tal.
