Five factors which should be considered when teaching vocabulary items to pre-school children ?

1. Age-appropriate vocabulary: Ensure that the vocabulary items being taught are suitable for the age and developmental level of the pre-school children. Use simple and concrete words that are relevant to their everyday experiences.

2. Contextual learning: Teach vocabulary items in context, such as through stories, songs, games, and hands-on activities. This helps children understand the meaning of the words and remember them better.

3. Repetition and reinforcement: Repeat the vocabulary items multiple times in different contexts to help children remember them. Use a variety of activities and games to reinforce the words and make learning fun.

4. Visual aids: Use visual aids such as pictures, flashcards, and props to help children understand the meaning of the vocabulary items. Visuals can make learning more engaging and help children remember the words better.

5. Encouragement and positive reinforcement: Praise and encourage children when they use the vocabulary items correctly. Positive reinforcement can boost their confidence and motivation to learn more words.
