Inshallah the salah chart will help them achieve a number of goals:
• Getting into the habit of praying regularly.
• Motivates them to increase the number of salah they pray each day.
• Reminds them when they have done their wudu and which salah they have prayed.
Depending on your child's age set a realistic target number of salah they should read in a week. Put a salah timetable in their bedroom to help them remember each salah time.
You will probably need to remind them as well. Each time they do their wudu and perform their salah they can give themselves a sticker.
To keep your children motivated agree on an extra special treat they will get if they achieve their target.
