Instruction on the Purpose of Similar Acts Evidence: This type of instruction aims to inform the jury about the purpose behind introducing evidence of similar acts.

Instruction on the Limited Use of Similar Acts Evidence: This instruction highlights the restricted scope of similar acts evidence.

Instruction on the Requirement of Substantial Similarity: This type of instruction alerts the jury to the significance of substantial similarity between the prior acts and the current offense.

Instruction on Balancing Probative Value and Prejudice: This instruction guides the jury on the delicate balance between the probative value of similar acts evidence and the potential prejudice it may cause. It advises the jury to evaluate whether the similarities between the prior acts and the current offense outweigh any unfair prejudice that may arise from the introduction of such evidence. 5.
