ie. 0.166
–
= 0.1(6) = 0.1666666666 ...
Clocks
Point of reference: 12:00 hours.

piece of pie/pizza) and read what
portion/percentage/ angle the se
-
lected piece represents.
Protractor
Point of reference: arm of an angle.
Set the disk of the protractor so that

int (the arm of the angle) and read the
angle.
The worksheets contain various types
of angles: acute, obtuse, right, reen
-
