Answer:
The best option for Mr. Jones to teach his students how to recognize maple trees is to take them outside to show them a maple tree and point out the differences between the maple and other trees. This will provide an authentic learning experience and allow students to observe the characteristics of a maple tree firsthand. Additionally, this option also provides an opportunity for students to ask questions and engage in discussion, which can enhance their learning experience. The other options may also have educational value, but they do not provide the same level of authenticity and experiential learning as taking students outside to observe a maple tree.
