There are 366 different Starters of The Day, many to choose from. You will find in the left column below some starters on the topic of Angles. In the right column below are links to related online activities, videos and teacher resources.

A lesson starter does not have to be on the same topic as the main part of the lesson or the topic of the previous lesson. It is often very useful to revise or explore other concepts by using a starter based on a totally different area of Mathematics.

Main Page

### Angles Starters:

Air Traffic Control: Work out which aircraft are in danger of colliding from their positions and direction of travel. An exercise in understanding bearings.

Angle Estimates: Estimate the sizes of each of the angles then add your estimates together.

Pie Chart: An exercise in estimating what the sectors of a pie chart represent.

Sectors: Work out which sectors fit together to make complete circles. Knowledge of the sum of the angles at a point will help find more than one correct solution to this puzzle.

Square Angles: Find a trapezium, a triangle and a quadrilateral where all of the angles are square numbers.

Angle Thinking: Find the range of possible angles, x, for which tan x > cos x > sin x

Curved Angles: How many right angles are there in a semicircle?

Geometry Snack: Find the value of the marked angle in this diagram from the book Geometry Snacks

Hands Together: The hands of a clock are together at midnight. At what time are they next together?

### Notes:

Pupils should understand that angles represent an amount of turning and be able to estimate the size of angle. When constructing models and drawing pupils should be able to measure and draw angles to the nearest degree and use appropriate language associated with angles.

Pupils should know the angle sums of polygons and that of angles at a point and on a straight line. They will learn about angles made in circles by chords, radii and tangents and recognise the relationships between them.

Pupils will work with angles using trigonometry, transformations and bearings. In exams pupils are often instructed that while non-exact answers should be given to three significant figures, angle answers should be given to one decimal place.
