## Working at Level 10 Mathletics, whats involved?

My son told me he is on level 10 in Mathletics, and that he gets the exercises right, but he does not really understand the consept of LOG, and what it means.

Neither do I. I dont even know what it is short for (and try googling Log, lol) Where can I find some good resources to help?

In our school we allocate the Mathletics Curriculum level each child works at. I have set most of my class to a UK Year 2 curriculum, a few I have set at Year 1 and a few at Year 3 - depending on their needs.

From what I can see all courses are set on a Year level that can be varied depending on the country. I think the level 10 has come from Mathletics live which we don't do, so hopefully someone else can help you with.

My google search did bring up this]]

Logarithms?

We did them in about 5th year secondary, but I think my parents generation covered them earlier. Don't think they're GCSE anymore, but may be wrong?

Hi It's quite simple actually. If it says something like( log 3 + log 4 )just change the + sign to a multiplication sign so the equation is now 3*4 which would equal 12. The same goes for subtraction equaling division.

I hope that helps.

Drowningbeast, I had same question as OP.
Ds worked out concept fine like OP's ds.
But what is log?

PP's link doesn't seem to work.

logarithms are a way of dealing with very big or very small numbers.

Imagine having a handful of marbles and needing to count them - easy. If you have a bucketful of marbles it will take a lot longer but if you have a roomful or a warehouse full counting them will take forever.

A logarithm is a consistent way to make a big number manageable for the purpose of doing some calculations with it, after which you can reverse the process to get back to the un-logarithmed state.

The first log usually taught is logarithm to Base 10. For any number, you can raise 10 to the power of something to get to that number. (I'm going to use ^ to indicate that the next number would be written small and high like a small high 2 means squared )

10^2=100 - this can be written log(100)=2
10^3=1000 - this can be written log(1000)=3
10^4=10000 - this can be written log(10000)=4

Obviously as 2+3=5 it must follow that log(100)+log (1000)=log (100000) and this demonstrates a general rule that logA+logB=logAB.

Logarithms are very useful for dealing with measuring things that can be really very big and also really very small. Sound on a decibel scale is logarithmic - 20 decibels isn't twice the volume of 10 decibels - it's 10 times louder, and 30 decibels is 100 times louder than 10.

Your primary DS is doing A-level maths? (That's where logs come in the curriculum)

School started using Mathletics and it came up on level 10, out of nowhere!

irvineoneohone Mon 14-Nov-16 09:19:11

I found this log and the concept seems easy enough for primary children, but I wouldn't go into anymore detail at the moment.

irvine it might be ok for your DS but trust me it's going to be very confusing for primary school children!

Even A-level students find it hard to get their head around.

IsItFridayYetPlease, yes, level 10 is for live Mathletics, which you can battle against other children in the world. So, actually nothing to do with levels school assign children to.( At least at my ds' school.)

Noble, I get your point.
Ds now spend far less time doing extra maths at home, since he found another interest(piano).
It just came with something school provided.
