Sort Objects by Two Properties
Name:

Today I am practising: classifying objects using two observable attributes
1
Collect four safe classroom objects. List or draw them.
2
Sort them into flexible and rigid groups by gently checking each one.
3
Within each group, separate objects made mostly of paper from other materials.
4
Choose one object and name both properties used to place it.
5
Could an object fit more than one material category? Explain your example.
6
Write a two-part rule for one of your final groups.
- Avoid sharp, fragile, or unknown objects.
- Allow mostly-paper categories when objects contain several materials.
- Ask the learner to explain borderline cases using observations.
