Start with hands-on activities and objects to help introduce the concept:

1. Cut a sheet of paper in half to model a fraction. Explain that a fraction is a part of a whole.

2. Show children an apple or another object they are familiar with and cut it in half or into quarters. Point out that we can use fractions to represent a part of it.

3. Have children practice cutting their own paper into halves and quarters using scissors. Ask if they are able to compare and tell if their halves and quarters are equal or if one is larger than the other.

4. Play a game of fractions by having kids practice making equal halves by folding paper or using other materials (colored blocks, etc) and then challenging them to make equal quarters.

5. Use real-life contexts to illustrate the concept of fractions, for example, if it is sunny outside, talk about how sunny days equals one whole, and if it rains for half a day it would be ½.

6. Introduce other numbers of fractions, e.g. thirds and fourths, and how these can fit into the fractions they already understand.

7. Use fractions problems and visual diagrams to help kids better understand the fraction concept.

8. Finally, it is helpful to review concepts introduced through music, stories, and free play to ensure retention.
