William's+Journal

​We are learning about time and temperature i would like to learn more about what happens when temperatures mix What do you mean when temperatures mix William? Can you explain this more? Please remember to date your journal entry. Mrs Breeds.

15 March timezones W.A.L.T. We are learning about different time zones around the world and how to calculate time differences. Timezones are diferent in different countries because in new zealand there is only one time zones because its so small there are lots of little lines on a certain map. its all because of where the sun is You needed more explanation of what the time zone lines do, and what they mean William, and then give an example from your learning today.

15 March celsius and farenheit WALT about the difference between celsius and farenheit for temperatures these are to different mesurements of heat. farenheit is the old one that the USA still uses. it is the imperial mesurement 32 degrees farenheit is 0 celsius celsius is the one NZ use. to get from farenheit to celsius you -32x5 divide by9 to get form celsius to farenheit you do it the other way round A good explanation of the theory we discussed today. An example of using the formula would've been good. Be careful of saying 'the other way around' though, better to actually give the other formula.

25 March W.A.L.T use algebra thinking to solve deceimal subtraction problems. eg. 10.82-8.93= +0.07 10.89-9=1.89. I am pleased that you learnt how to use this strategy. How did you find using it? TC

29 March WALT:use temperature as a strategy to help us add and subtract integers eg: positive 5 +negitive10=negitive5 +=warm -=cold you have 5 warm and put in 10 cold it makes it below 0 so it is 5cold/negitive 5 -5- -8= +3 because you take out the cold Excellent learning today William. It would be great to know how you find learning new strategies. PLease adda comment.

19 April Today we learnt about problem solving strategies eg known facts and i want to know what the factor tree is and i probably have know it but didn't know what it was called. I now know that there are a lot more strategies than I thought. Which ones do you see yourself being able to use in the competitions William? Perhaps looking at factor trees could be a good idea for your mathletics investigation teaching mobile.

26 April Today i learnt what a histogram is. it is a type of bar graph that you use for continuous data you put the countable numbers on the y axis. What do you mean by continuous data William? Are you able to explain the difference between the column graph and a histogram? Histograms have the columns are joined and column graphs are apart.

6th May I learnt what a box and whisker graph is and what a lower quartile and a upper quartile is .The lower quartile is the 25% point .The upper quartile is the 75% point above.A box and whisker graph starts at the start of the first whisker (lowest number) which is 25 % below the the median box (25-75%) and then there is the other whisker (75-100%) Good explanations. Do you feel confident in being able to interpret this type of graph? yes

13 May Lately we have been getting our survey's ready. It was frustrating when they wrote something that was completley not the topic eg i asked what one of the social networking websites they used the most and they wrote miniclip.

20 May It has now been a week and some people still have not given me back some of my surveys. Today we looked at tutorals on excel.

27 May Today we did our second otago maths competition and i got 4/5. I think I did well because it was a lot better then last time and I checked my answers. I found that the last one was really hard and i did not know how to solve it so i guessed it. I've got all my data but I'm behind on that work. Remember that you can come at lunch or after school when I am available. Great result for Otago and it is neat to see that your checking provided that extra push for points.

28 may my goal for the next otago maths is to get the same high score results as last time and to check my awnsers again.
