This Year 5 Understand Negative Numbers Teaching PowerPoint introduces children to negative numbers. Linked closely to our worksheets, this resource begins by recapping missing numbers on number lines before moving on to explore negative numbers in real-life contexts. Pupils will focus on temperature, lifts and sea level measurements whilst practising putting negative numbers on number lines. Our teaching slides include a selection of fluency, reasoning and problem-solving questions, along with answers, to help develop a secure understanding.
