Encourage deeper thinking with this Year 4 Perimeter of Rectilinear Shapes Discussion Problem, which presents children with two reasoning and problem solving style questions based around perimeter of rectilinear shapes.

Use after our Modelling PowerPoint, Varied Fluency and Reasoning and Problem Solving worksheets to make sure children have a thorough understanding of perimeter before they tackle these problems, which are in depth and 'meaty'. An answer page with example answers is included, so your marking will be a breeze. Why not encourage peer or self marking amongst your children to facilitate even more conversation about perimeter?
