For some kids getting stickers on their reward chart will be all they need to keep them motivated.
Other kids will be happy to receive compliments and don’t need any other incentive.
Some kids will want a prize when they complete their chart or each time they are successful.
We call this a “5 a day prize” and if you are going to give one then you might find it helpful to keep a jar of small prizes handy during meal times.
See what works for your child.
