Daniel+H's+Journal

We are learning about time and temperature. I would like to learn more about farenheit. I would like to know how to convert farenheit into temperature and how it is measured. Daniel, we will be looking at this next week. Farenheit is an old measure of termperature that has mostly been replaced by celsius. We will be learning how to convert between the two.

W.A.L.T. We are learning about different time zones around the world and how to calculate time differences. Time zones revolve around the sun. Daytime is when the sun is up and night time is when the sun is around the other side of the earth. There are 24 different time zones in the whole world. Time is measured from a place called Greenwitch. Greenwitch is in London, England. Time is measured by these invisable lines. E.g. Greenwitch is at 0 and New Zealand is at +12. A clear explanation Daniel. If you had then given an example of the time difference between NZ and another country this would've been a perfect entry!

WALT: We are learning about the differences between Celsius and Fahrenheit for temperature. We have two measurements for temperature because they used to use Fahrenheit to measure temperature but then replaced it with Celsius. To work out the differences between these two you go C=(Fahrenheit -32) /1.8. 356 F = 180 C 356 - 32 = 324 324 / 1.8 = 180 Good - and an example of using this formula?

WALT: We are learning about exchange rates for currency. I have learnt that if you bring $100.00 to a country it might be $1000.00 in that country. E.g. $1.00 New Zealand might be 70c U.S.A. Yes - or it might be less!

WALT: Use algebraic thinking to solve decimal subtraction problems. Today I have learnt a new stratergy. It is called algebraic thinking. E.g 5.12 - 3.89 +0.11 +0.11 5.23 - 4.00 = 1.23 Daniel I am pleased you learnt something in Maths today. How do you feel about using this new strategy. Would you use it in the future? TC​

//__**26/03/10**__// I feel like this strategy has made subtracting decimals 10x easier. I would always use this in the future. Great Stuff! TC​

Today we learnt how to add and subtract intergers. To work it out we pretended the numbers were water temperatures. W.A.L.T: Use temperature as a strategy to help us add and subtract intergers. E.g +5 + -9= -4 Imagine you have a bath and the temperature was +5. You thought it was too hot so you thought you might + -9 which in other words means you would add cold water. +5 + -9 = -4. You have learnt something in Maths today- Great! Would you use it? Does it make this concept easier to understand? TC

W.A.L.T: Add don't subtract when working on decimal subtraction problems. E.G: 2.91 - 1.32 = 1.59 1.32 + 1.59 = 2.91 Much easier than subtracting! But I think the algebraic thinking is a bit more easier.

Great work Daniel. I have really enjoyed going through your work from Term 1 with you. I can see that you are trying really hard to do your best - keep it up. Julie

W.A.L.T: We are learning to use a number of different problem solving strategies to solve complex problems. Today I learnt a lot of new strategies. One of them I learnt was looking for a pattern. We did some Otago Problem Solving today and tried out some of these new strategies. I currently only use two different strategies for problem solving but by the time we finish this unit I would like to know four different strategies. That is great Daniel. I would really like you to be comfortable in using at least 5 of the more user friendlones: guess and check, work backwards, look for a pattern, use a known fact and use a diagram or graph.

W.A.L.T: Find out what we know, what we think we know and what we don't know. I know how to do a telly chart, a bar graph and display data. What I think I know is how to do a line graph I do not know how to do a histogram.

W.A.L.T: To find out what graphs we know. Today I learnt how to do a Dot graph, a back to back dot graph, stem and leaf graph and a scatter plot. A dot graph is used for counting tallies. A back to back dot graph is used to count two tallies. A stem and leaf graph is a graph that has a stem in the middle with the tens numbers or higher in it. It has leaves on the side for the one numbers. A scatter plot is like a line graph without lines. Good reference for yourself later Daniel. Remember that a dot plot can be used to show data and to collect data - it is multi purpose.

W.A.L.T: Evaluate statments about graphs. Today we were learning to be able to interperate and crerate statements about graphs. I think I did good because I supported my statements with data on the graph.
 * //__4/05/10__//**

W.A.L.T: To do a Box and Whisker graph. Today at maths we were learning how to do a Box and Whisker graph. At first I found it hard to understand but then I got used of it. A Box and Whisker graph is really useful for finding the median. I would use a Box and Whisker graph in the future. Useful for showing the median and range of data. It is also really good for large amounts of data to see the outliers.
 * //__5/05/10__//**

It is great to see that you are learning to do so many different graphs which I know you will use in the future. Keep up the good work. Julie

Today we were learning how to do a mathmatical design on the computer. It had to be symmetrical shape/patteren and it couldn't be clustered. It also had to have a border. How did you go with yours? Remember that translation and rotation of a shape can form some wicked patterns.

Yesterday we did our first olympiad test. I got 4/5 because I did not read the question properly. Daniel 4/5 is a great result so don't be so hard on yourself. Remember that using another strategy to check can often pick up those mistakes.

Today we discussed our teaching mobiles and got feedback on them.
 * //__24/05/10__//**

//__**27/05/10**__// Today we did an Otago Problem Solving test and I got 5/5. And....I would love to hear the excitement you felt Daniel as this is an awesome result and something that you should be really proud of.

A few days ago we did a IKAN test.I need to practise on my basic facts because I got none right on stage 8. I need to improve on my place value because I only got half of them right on stage 8. Good goals to have Daniel. There are some great websites that can help you practice these as I think all you need is practice - the knowledge is actually there. Check out the nzmaths website - the families section for some activities you can use. Also google these activities under the heading games and you will come up with some really worthwhile things.

Today we had an olympiad test. I got 3/5. Some of the questions were hard to understand.

Yesterday we had an Otago Maths Test. I got 3/5. The last question was really hard and the other one I didn't get I misread it. I can try and not misread it by not feeling under time pressure as much.
