This is a three options test:

**Find the perimeter :**

Determine, through investigation using a variety of strategies, the perimeter of a given figure. Click on each individual square to highlight the outline.

**Find the (surface) area :**

Determine, through investigation using a variety of strategies, the surface area of a given figure. Click or move around each individual square to reconstruct the figure according to your strategy..

**Construct a surface given the area and perimeter::**

Drag and drop on the scene several one-unit or four-units squares. Click and drag each individual square to create an original figure according to the specifications. Show how two shapes can have the same area measure but have different perimeters.

**Answer **the questions using your keyboard or the digital pad provided in the simulation.

- Show how two shapes can have the same area measure but have different perimeters.
- Determine perimeter and surface area, through investigation using a variety of strategies.
