Contextual Connections of Speed
 

  • Cross-Context of Unit Price
  • Concept Enlightenment: Who Is Faster, Who Is Slower
  • Exploring Speed: How Fast Do I Run?

Invariant Relationships Between Two Variables in Daily Life

  • Daily Code: Constant Sum and Constant Difference
  • Daily Code: Constant Product and Constant Quotient
  • Decoding the Code: Identifying the Invariant Relationship Between Two Variables

The Classification of Quadrilaterals
 

  • Defining Activity for Rectangles
  • Finding the Properties of Special Quadrilaterals with Bidirectional Activities
  • Subordinate Relationships of Special Quadrilaterals

The creativity in finding areas can be used in
˙Making atypical parallelograms
˙Deducing the areas of triangles and trapezoids by dividing parallelograms equally
˙Creating shapes and examining areas
˙Cutting and reconstructing to find out that the area is the same if we trim the curved area to piece it back into a straight-edged shape

Integrating the Categorization of Trianglesto Promote Reflective Thinking Skill

Through
˙The warm up in reflective thinking
˙Reflecting on categorization of triangles
˙Giving examples to integrate the categorization of sides and angles of triangles
Foster systematic thinking

The Systematic Thinking of Categorizing Triangles
 

˙Establishing the relationship between side and angles of triangles
˙Categorization of triangles: Categorizing and naming by the characteristics of the sides
˙Categorization of triangles: Categorizing and naming by the angle types
˙Integration of the two types of triangle categorization systems
To develop systematic thinking
