Okay so today we were introduced to percents.
In class we had to use 10x10 grids for solving percent problems.
For example if we had to shade in 65% of the grid we would shade 65 squares. Why? because percents are out of 100. We also had to show if we messed with a square so then we just make some sort of pop out to show what we did.
Well Harbeck tricked a lot of people when he said to fill in 3/4 of the grid a lot of people thought that 3/4 was 75% of the square so the shaded in 75% of the square but it actually meant that it only 3/4 or 75% of 1 square.
In class we also made a foldable.
In the foldable at the first flap we had to find the definition of percent and fractional percent. Under that we had to draw out what 180% , 0.6% and 12 3/4% looks like on a grid. We just have to draw it out and show a pop up where we messed with the square.
Percent- is a way of expressing a number as a fraction of 100.
Fractional Percent- a percent that includes a portion of a percent.
