Reflecting, rotating, and translating a shape changes its position, but its area remains the same. Students play a game that involves placing shapes of different area inside a “shipping container”. This game can be easily adapted to incorporate the language of geometry (reflection and rotation).
colouring-in pens or pencils
3 classmates
a paper clip
game board and spinner (see copymaster)
In this game, students use reflection and rotation to position shapes inside a rectangle.
Ask the students to identify whether they are rotating or reflecting the shapes shown on the spinner before they add them to the shipping container. Students who find this challenging could make paper copies of the shapes. If the paper copy needs to be flipped over, the transformation is a reflection.
See Digital Learning Object: Pentominoes (www.meaningfulmaths.nt.edu.au/mmws/nz) for a similar activity.
The pieces on the spinner in the game can be used as a basis for further exploration by asking the students to:
Have the students draw a 6 x 6 square. They take turns to colour in squares using the shapes on the spinner. Each player can only use each shape once. The winner is the last person to be able to place a shape within the square.
This alternative game can be adapted to make it more collaborative. Students still take turns placing or colouring in a piece, but the challenge is to have as few squares left uncoloured as possible.
The shipping container game and its variations provide a good opportunity to have the students listen actively to each other and build on others’ ideas. The key competency relating to others involves recognising when to compete and when to co-operate.
Optimisation is important for designers and manufacturers. Efficient use of materials, time, and energy all have an impact on decision making. Over time, storage and packing technology has changed, including the introduction of containers. (Try an Internet search on the history of freight containers.)
Packaging serves several functions. It stores and protects items, advertises them, and disseminates product information.
