If your mathematics target involves learning multiplication tables then you should read this blog post. It may help you focus on the multiplication tables that really matter to you.
A group of eight children in Class 6 were measuring water using measuring cylinders. They coloured the water to make reading the scales easier. They lined up the cylinders in two neat rows, each labelled with a child's name and the amount they had measured out. Then Harry opened the window and the wind blew most of the labels onto the floor! "Oh! Harry!" they all wailed. Can you relabel the cylinders for them? Ahmed had measured out just a thousand millilitres and Belinda twice as much as Ahmed.
Grace had measured out three-quarters of the amount that Belinda had done and Freddie had half the amount that Ahmed had measured out. Which were their cylinders? Callum had coloured his water blue. How much did he measure out? Ellie had coloured her water pink and Dan coloured his orange. How much did they measure out? "Don't drink that!" Harry had laughed, pointing at Dan's cylinder, "It's not orange juice!" As his hand stretched out he knocked over his red liquid. "Oh! Harry!" they all wailed again. How much was left in Harry's cylinder after the accident? This is the latest sofa challenge and it is TOUGH. You need to answer questions a, b, c and d. The yellow question is optional. If you get that one correct you can take the sofa home.
Before the holidays we were looking at time as your planned your own holiday vacations. We're going to look at time in a slightly different context this week. Here are a couple of problems to get you thinking. If you can't figure them out, then take a look at this from Khan Academy.
The holidays are coming up. If you were planning your own trip where would you go?
I would like you to plan a trip and try to think about the following things:
Yesterday we looked at time zones around the world. We figured out that there are 24 time zones and each one os 15 degrees wide because 24 x 15 is 360 which is a full rotation of the globe. I asked you what wonderings you have and you came up with some interesting ideas: Why do we need time zones? How can it be a different day in other countries? Is it possible to have time difference inside 1 country? What did people do before time zones were invented? Who invented time zones? What is GMT? What is swahili time? Here is a quiz you can try. Here is the latest sofa challenge. The first four correct answers, emailed to me, will get the sofa until the holidays.
Look at the sequence of letters. Can you tell me what two letters come next? O, T, T, F, F, _ , _ |
