Concept:Using both examples and non-examples helps primary students clearly understand a concept by seeing what it is and what it is not.
Explanation:Examples show similar situations that match the concept. This makes new ideas easier to learn.
Non-examples show contrasting situations. This pushes students to think critically and notice key differences.
Only giving examples may leave students confused about boundaries. Only giving non-examples can cause misunderstanding.
So, a teacher in a primary classroom should provide both. This builds self-awareness, sharpens thinking, and keeps students engaged.
Answer:B. Give both examples and non-examples
