Lesson Worksheet: Turns and Angles Mathematics • 4th Grade

In this worksheet, we will practice describing angles as fractions of a turn and using the fact that a whole turn measures 360 degrees to work out the measures of fractions of a turn.

Q1:

Write the measure of the angle in degrees and as a fraction of a full turn.

  • A90, 34 of a turn
  • B270, 12 a turn
  • C180, 34 of a turn
  • D360, 12 a turn
  • E90, 14 of a turn

Q2:

Write the measure of the angle in degrees and as a fraction of a full turn.

  • A180, 12 a turn
  • B360, 12 a turn
  • C180, 14 of a turn
  • D90, 12 a turn
  • E360, 14 of a turn

Q3:

Scarlett makes a quarter turn. How many degrees did she turn?

Q4:

Write the measure of the angle in degrees and as a fraction of a full turn.

  • A270, 12 a turn
  • B360, 12 a turn
  • C90, 34 of a turn
  • D360, 34 of a turn
  • E270, 34 of a turn

Q5:

Write the measure of the angle in degrees and as a fraction of a full turn.

  • A90, 14 of a turn
  • B180, a full turn
  • C180, 12 a turn
  • D360, 12 a turn
  • E360, a full turn

Q6:

Noah wants to divide a circle-shaped colored paper into 6 equal parts. What is the angle of each part?

Jennifer wants to divide a circle-shaped piece of cloth into 4 equal parts. Find the angle of each piece.

A carpenter wants to cut a circular tree trunk into 3 equal parts. What angle should he measure to make sure the parts are the same?

Q7:

Every time the turtle turns, he turns 60. If he ends up turning in a full circle, how many 60 turns did he make?

Q8:

There are 360 in a circle. How many 30 angles are in a circle?
