The Year 4 Change PowerPoint guides both teachers and children through the lesson, including use of the varied fluency, reasoning and problem solving, deeper reasoning and scaffolded resources. Key learning information about this step:
Key Vocabulary
area: The measurement of the surface of a 2D shape. It is measured in unit squares such as centimetre squared (cm²).
arrays: A visual representation of a multiplication.
systematically: Working in an organised way.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
Scaffolded Examples
• Using rows to find the area by counting squares.
Support
• Q1: Find the area of two shapes by counting; the first row is counted.
• Q2: Tick two correct statements about 2 half squares; a reminder is given.
• Q3: Match three small rectangles to statements; count the rows first.
Core
• Q1: Find the area of two rectilinear shapes by counting squares.
• Q2: Tick two correct statements about a shape with 4 half squares.
• Q3: Match three rectangles to statements giving rows and the area.
Stretch
• Q1: Find the area of two rectilinear shapes that require keeping an accurate systematic count.
• Q2: Tick two correct statements about multiple half squares; more complex shape.
• Q3: Match rectangles to statements giving only the rows or only the area.
Reasoning and Problem Solving
Support
• Q1: Reasoning – explain a character's area for a shape with uneven rows; reminder given.
• Q2: Reasoning – explain whether a statement could be correct about a part-covered rectangle; hint given.
• Q3: Problem Solving – find 3 possible numbers of hidden squares of a paint-covered rectangle; area range given; table provided to support calculation.
Core
• Q1: Reasoning – explain a character's area for a shape with uneven rows.
• Q2: Reasoning – explain whether a statement could be correct about a part-covered rectangle.
• Q3: Problem Solving – find 3 possible numbers of hidden squares of a paint-covered rectangle; area range given.
Stretch
• Q1: Reasoning – explain a character's area for a shape with half squares.
• Q2: Reasoning – explain whether a statement could be correct about a part-covered shape; total area given.
• Q3: Problem Solving – find the area of a paint-covered shape; consider half squares.
Deeper Reasoning
The questions in this set focus on problem solving with area to deepen understanding in finding the area of rectilinear shapes by counting squares.
