Turn or Slide, Keep the Shape

Today I am practising: recognizing properties preserved by movement
1
Draw a small triangle on scrap paper and cut it out with adult help. Count the vertices.
2
Trace it, slide it to a new position and trace again.
3
Turn the cutout and trace a third time.
4
Compare the number of sides in all three traces.
5
Did sliding or turning change the triangle's size? Explain.
6
Draw an arrow showing one slide and a curved arrow showing one turn.
- Use blunt scissors with adult help or a ready-cut triangle.
- Keep the cutout flat while tracing.
- Compare the same corners across traces rather than relying on 'pointing up'.
