Glenda Said:

What's your most pointless day at school yet?

Hmm, lets see,
First Block-Learn about planes and the wright brothers, which we all learned in like fifth grade, make paper airplanes and race them down the hallway
Second Block-Teacher sings to us a Christmas song in the middle of April, assignment was to find a song on our mp3s that might have a double meaning. My choice? A Britney spears song
Third Block-Had a substitute, who didn't show up for class, so we made pointless videos and had a talent show.
Computer-make-up your work day. AKA play on the computer day
Gym-watch the coach play dodge ball with the art teacher.
fourth block- science class, teacher wasn't feeling good so we colored her pictures until the end of the day

i think i could have stayed home that day and not missed a thing, yeah?

Mental Math Strategies - Where Can I Learn The Fastest Mental Math Shortcuts?

'Fun with Figures' is my personal choice and recommendation. It includes an in-built mental math software as well -- apart from a book and worksheet pdf.

An example of mental math is when you want to find percentages or square roots of large numbers without using a calculator. Say you want to find the percentage of a number:

Finding 33 1/3 percent of a number

Step 1: Choose a number
Step 2: Divide the number by 3

Example:
If the number selected is 92
Divide by 3: 92/3 = 30 2/3 (or 30.67)
So 33 1/3% of 92 = 30 2/3

Other ways to count vs. using manipulatives, such as fingers?

using counters is always better - straws, pegs, checkers pieces etc
