Exploring Percents Greater Than 100 and Less Than 1

The video tutorial covers the concept of percents greater than 100% and less than 1%. It explains how growth can result in percents over 100% using examples like sales increase and rainfall comparison. The tutorial uses flashcards and 10x10 grids to model these concepts visually. It also includes practical examples with kitten weight and elephant height to illustrate percent increase and comparison.

Why is it mathematically impossible to give more than 100% effort?

• Because effort is always measured in percentages.

• Because effort cannot be quantified.

• Because 100% is an arbitrary limit.

• Because 100% represents the maximum possible effort.
