## 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 #### Aunt Sophie's Post Office

Work out the number of stamps needed to post a parcel.

### 2nd Lesson #### Blots

The calculations are obscured by ink blots. What do you think the calculations would look like if there were no blots?

### 3rd Lesson #### Exponential Error

This lesson starter presents a number of statements about indices and pupils are asked if they can spot the mistake.

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.
