## Lesson Starters

Here are some suggestions for whole-class, projectable resources which can be used at the beginnings of each lesson in this block.

### 1st Lesson

#### Angle Estimates

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

### 2nd Lesson

#### 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.

### 3rd Lesson

#### Square Angles

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

### 4th Lesson

#### Dice Reflections

A dice is reflected in two mirrors. What numbers can be seen?

### 5th Lesson

#### Dice Nets

Determine whether the given nets would fold to produce a dice.

### 6th Lesson

#### Faces and Edges

Find the number of faces, edges and vertices on some familiar objects.

### 7th Lesson

#### Icosahedron

How many triangles are there on the surface of a regular icosahedron.

### 8th Lesson

#### Get A Wiggle On

A mixture of calculations to get your brain working at the start of a mathematics lesson.

### 9th Lesson

#### Refreshing Revision

It is called Refreshing Revision because every time you refresh the page you get different revision questions.

Some of the Starters above are to reinforce concepts learnt, others are to introduce new ideas while others are on unrelated topics designed for retrieval practice or and opportunity to develop problem-solving skills.
