Final answer:
The best activity for kinesthetic learners is creating masks traditionally used in the Ponce Carnival in Puerto Rico because it provides physical engagement and a hands-on experience.
Step-by-step explanation:
The activity that will best engage kinesthetic learners in preparations for National Hispanic Heritage Month would be creating masks like those traditionally used in the Ponce Carnival in Puerto Rico. Kinesthetic learners learn best when they are able to use their hands and engage in physical activities. Crafting masks allows these learners to connect with the culture through a tactile and imaginative experience, embodying a unique aspect of Puerto Rican heritage. Activities such as comparing monetary systems or identifying geographic features on a map, though beneficial, do not offer the same level of physical engagement. Similarly, observing dances is a visual experience and may captivate learners but does not involve active participation.
