Estimating lines & Angles

I will investigate whether people picked at random can estimate line length better than angle size.

I will then develop it by studying my answers and see if e.g 11 year olds are at estimating line length or angle size than 16 year olds.

Hypothesis:

People are better at estimating line length than angle size

16 year olds are better at estimating line length than 11 year olds.

Method:

* I'll draw 3 Lines on plain paper at different angles so they can not use markings on the paper to guess or help them get the length.

* I'll also draw 3 angles on plain paper at different angles so they can not use markings on the paper to guess or help them get the size.

* Then I'll pick the students a random by first numbering all the students, then using the random number generator on the calculator I can find the students I want by converting that number - e.g 88 - to a person - e.g Joe Bloggs year 7

* Then we will collect the data by going round to the people needed, if 2 people needed are in the same lesson, using my associate, I will take 1 person to be quizzed while the other is out of the way, at another desk or room so there is no conferring or the other person influencing the other.

My 3 lines:

Line 1's length = 5CM

Line 2's length = 12.5CM

Line 3's length = 6.6CM

My 3 Angles:

Angle 1's size = 60°

Angle 2's size = 105°
