QTR 2 DAY 8 (11.9.2016)

The days are too short!

 

Today we quickly finished up those notes from yesterday in some classes (others were already finished thankfully)

We then talked quickly about exponentiation.

And how something like:

2^3

Does NOT mean 2 x 3!!

 

We discussed powers of ten, and how in our BASE 10 system, the BASE of all of our place values, is 10!

So something such as 456

Is made up of:

4 x 10^2

5 x 10^1

6 x 10^0

 

We did a quick example of this in our example notebooks, and also a quick explanation of why anything raised to the 0 power is 1.

So in any base system, the base is what we group in, and each place value is based on that number.

 

Finally we talked a bit more about base 2, and then did some work writing numbers in base 2.  Tonight students should finish this worksheet (the front) if they have not already:

Tomorrow we will do some more work with base 10 and other bases, and do some centers that give us a good bit of practice.

 

Have a good one,
