A COTA is working with a child on tooth brushing. The COTA lets the child brush the teeth for a minute. The child fails to brush the majority of the teeth. Next, the COTA uses the toothbrush to brush all of the child's teeth. What strategy is the COTA using with this child

Foward chaining

Explanation: Chaining is a behavioural strategy that teaches a skill by breaking it into  steps by step procedure which depends on the nature of task to be achieved and the level of the individual being taught

Forward chaining is a type of  behavioral chain strategy  which teaches a skill by beginning with a first step that lets a child or individual  complete an action  independently which is then followed by helping the child or individual  complete the  remaining steps. Using the tooth brushing by COTA in this case example, the child is allowed to independently brush the teeth for a while, then all remaining steps in ensuring that the child's teeth is thoroughly brushed is then completed.
