• Pupils will investigate measurement by direct comparison and by non-standard units.
• Pupils will compare lengths of a certain object.
• Pupils use the measurement tool as a non-standrad unit for measuring lengths.

• The concept of a unit for measuring area.
• Measuring various objects with different units of measurement.
• Comparison of shape areas using a non-standard unit.

There is no special model but the units of area (squares) should be kept in a folder.

The lesson of comparison of areas 1/3 should precede this lesson.

Understanding the concept of a unit for area measurement and comparison of area size using the same unit.

Three origami sheets 15cm x 15 cm.

• Recognition of the concept area by direct comparison of shapes.
• Comparison of area size by congruency and decomposition of shapes.
• Comparison of areas using a basic shape.
• Decomposing shapes in order to find areas of composite shapes.

According to curriculum

Composing new polygons from a basic triangle shape and comparing areas in relation to the area of the basic triangle shape.

• The pupil will recognize length and area units.The pupil will calculate area measurement of a rectangle as multiplication of the length of a row multiplied by the number of rows.
• The pupil will discover that equal areas of  rectangles does not always mean equal perimeters.
