LI: identify and construct right, acute and obtuse angles and to begin to appreciate the degree, unit of measurement of angle, also to know the degree value of angles that are simple fractions of a whole turn and know that the angle at a point is 360°
This week for Maths we learned how to use a protractor. We had a sheet. There were angles on the sheets, we had to measure the angles and write down what the angle was. We learned by remembering the five different angles we learned last week. The five different angles we learned last week is:
Right angle: exactly 90 degrees
Straight angle: exactly 180 degrees
Acute angle: 0 - 90 degrees
Obtuse angle: 90 - 180 degrees
Reflex angle: 180 - 360 degrees
This is how to use a protractor: https://www.youtube.com/watch?v=LPc0imoebzI
