So, it s a good idea to divide the block of time into smaller sections. Here are some activities that can add to the fun of a class period at any level of instruction. Begin each class period with some kind of reading. Consider allocating the first five minutes of any period for this activity. Your reading can relate to the subject matter at hand if you like, but that s not really critical.
Any valid material is worthwhile.
Have a repertoire of demonstrations to do. The nature of the demonstration depends on the nature of the subject you re teaching or the topic at hand. If you prepare a series of 5 to 10 minute demonstrations ahead of time, you ll have them ready. Keep an inventory of things to pass out for students to examine. Again, your inventory will depend on what you re teaching.
