We started off by Mental math then marked our papers. Then we were taught how to calculate the surface area of 2 boxes.

A box with 4cm Length, 4cm Width , and 4cm Height:
6x4x4=
6x16=96cm2

A box with 15 cm Length, 2cm Width, and 4cm Height:
=2(15x2)+2(15x2)2+(2x2)
=2(30)+2(30)+2(4)
=60+60+8
=128cm2

After we did a quiz to review the things we've been doing in class to get ready for our exams. I had a pretty difficult time with it. But I'm getting more familiar with the shape formulas and things like that. Hopefully i get used to it before exams start.

The next scribe will be Aaron.

We started off with some mental math as usual. Then after marking each others paper we were taught how to represent scales in two different ways.
Example:
1:25 can be shown as..
-1 unit to 25 units
-1 over 25
-1/25
-1 cm represents 25 centimeters
-1 inch represents 25 inches

Example:
-1 cm represents 6 km
-1cm to 600 000cm
-scale : actual
-scale over actual

We also reviewed K-H-D-M-D-C-M. Then after we did some other scale activities.

Today in math we did our usual mental math test. Mr. kuropatwa taught us an easier way to multiply. For example if we needed to multiply $6.25 x 4 instead of doing it the more difficult way and multiplying it by 4 or multiplying each digit.. we could take $6.25 and times it by 2 and that gives you $12.50 and then you take $12.50 and times it by another 2 then you get $25.00.
Another example is ..
$14.25 x 4
$14.25 x 2 = $28.50
$28.50 x 2 =$57.00
