From two different street sign pictures and their enlargements, students are to identify the scale factor of each enlargement and either a missing length or the missing factor when enlarging the area.
Students design school library badges by creating four symmetrical patterns using 2-dimensional shapes. A display board template is included for students to put their work on.
In this practical task students use a ruler, a protractor, and a compass to enlarge an arrow by two given scale factors. They then complete a table to show the invariant properties.
