Mitchell+F's+Journal

__12.03.10__ W.A.L.T. We are learning about different time zones around the world and how to calculate time differences.today we did a F.I.O activity.we had to calculate flight times to different places in the world.I learn't that basically every place in the world has a different time. Mitchell, this is mostly a description of what you did today, not what you learnt. The question I asked you was to explain what time zones are and give an example from your learning today. Go back and read the notes on the main journal page and have another try at answering the question in your next journal entry. Mrs Breeds.

__15.3.10__ W.A.L.T. We are learning about different time zones around the world and how to calculate time differences.Time zones are different sections of the world that have different times.Time zones are based on the movement of the sun and are calculated from a place in England called Grenich.It is called GMT (Grenich mean time.) It depends how far away from Grenich in the world you are to what time it is. Much better. You still need an example though.

__18.03.10__ W.A.L.T. We are learning about exchange rates for currency.To figure out the exchange rate you multiply the N.Z dollar by another countries.e.g if the american dollar is 0.45592 and you had $800 N.Z then you would get 455.92 U.S$.I found this work really interesting because I learnt that you can either get lots of money for a N.Z dollar or a pathetic amount.I found it easy once I got the hang of it. Clear examples.

__19.03.10__ W.A.L.T we are learning about the difference between celsius and farenhiet for temperature.We have two different types of measurements because farenheit was used years ago but is now only used in countries like America.Today celsius is used all over the world.To convert farenhiet to celsius you have to subtract 32 then times by 5 then divide by 9. I learnt the formula to convert farenhiet to celcius. Great - can you show an example of how to use the formula?

__24.03.10__ W.A.L.T use algebraic thinking to solve decimal subtraction problems. today we learnt a new strategy for subtracting decimals e.g.if you had 2.25-0.75 you add 0.25 to make it 2.5-1. I would definitly use this strategy again because it is really simple and easy. I am pleased you enjoyed using this strategy Michell. Thanks for your open and honest reflection. TC

__25.03.10__ W.A.L.T use temperature as a tool to help us work out interger problems.This strategy is really helpful to work out negative and positive and is also easy to remember.e.g.if you have a pool that is 7 degrees celcius and you take away negative 2 you just add 2 degrees. A really good strategy to keep in the back of your mind when solving integer problems.TC

__31.03.10__ W.A.L.T add don't subtract when working on decimal subtraction problems.yesterday we learnt a new strategy for making decimal subtraction problems into addition problems.e.g.if you have 3.76 -1.64 you can make it 1.64+?=3.76 1.64+.06=1.7 1.7+.3=2 2+1.76=3.76 .06+.3+1.76=2.12

__19.04.10__ W.A.L.T use a number of different problem strategies to solve complex problems.Today I learnt a new strategy called look for a pattern you can look for a pattern to figure out the answer quicker. It is important that you have a number of strategies to choose from Mitchell - so that you can choose the right strategy to meet the needs of the problem.

__26.04.10__ Today we learnt about scatterplots.Scatterplots show data with dots.e.g.if you caught a fish 2.2 kgs and 46 cm long you would go 2.2kgs across the graph and 46 cm up the graph then put a dot there.This graph is really easy to use once you know how to use it. It also shows the relationships betwen two sets of data.

__7.5.10__ Box and whisker graphs show medians and quartiles.I learnt how to use a box and whisker graph.they are pretty easy graphs to use.I found the hardest bit is ordering the data.

__14.5.10__ We have been doing a statistical investigation. We have to send out a questionaire to get our answers.I found that writing surveys is harder than it looks. Writing quality questions that dvelop on from each other is a hard thing to do Mitchell but one that you get better with wtih practice. I would have liked to have seen a journal entry regarding your graph to the right and your use of excel - where is this one?

27.5.10 We did another otago maths today.I got 3/5. for the first question i forgot to add the 3 pancakes.for the second question i added them up to 90 instead of 100.
