Teach integers through real-world contexts with this comprehensive and editable 30-slide teacher presentation, designed to explicitly teach how positive and negative numbers are represented on number lines and the Cartesian plane.

Built around the I Do, We Do, You Do model, this teacher slide deck provides a scaffolded pathway from explicit teacher modelling to guided exploration and supported application. Students investigate authentic contexts such as elevation and sea level, learn to interpret positive and negative values, and develop confidence locating, representing and plotting integers on number lines and the Cartesian plane.

These teacher slides can be used independently. Note: Where the teacher slides reference printable independent activities, these are available in the full lesson bundle.

Through modelled examples, collaborative discussion and structured learning experiences, students represent integers using number lines, interpret changes above and below zero, plot and identify coordinates on the Cartesian plane, and explain their mathematical reasoning using appropriate mathematical language.

What's included in this teacher slide deck?

• 30 editable PowerPoint slides following the I Do, We Do, You Do lesson structure
• Clear learning intentions and success criteria focused on representing integers on number lines and the Cartesian plane
• Explicit teaching and modelled examples using real-world contexts such as elevation and sea level
• Guided practice locating, comparing and interpreting positive and negative integers
• Explicit instruction demonstrating how to plot and interpret coordinates using the x-axis, y-axis, origin and all four quadrants
• Interactive check-in questions to monitor understanding throughout the lesson
• Opportunities for students to explain and justify their mathematical reasoning using visual models and mathematical language

Perfect for upper primary classrooms, this editable teacher slide deck develops students' understanding of integers by connecting mathematical concepts to authentic real-world situations. Students build confidence representing, interpreting and plotting positive and negative integers while strengthening spatial reasoning and coordinate skills.
