Find fractions between two given values.

### 2nd Lesson

#### Less Than

This mathematics lesson starter invites pupils to interpret a three part algebraic inequality.

### 3rd Lesson

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.
