Final answer:
The best example of sequential instruction is teaching the concept of vowel teams, then teaching these long a vowel teams in the order of ai, ay, ei, eigh. This approach builds upon the general understanding of vowel teams, progressing to specific examples in a structured manner.
Step-by-step explanation:
When considering which is the best example of instruction that is sequential, the ideal option would be one that presents information in a logical progression that builds upon prior knowledge. In this context, the best example is d. Teaching the concept of vowel teams, then teaching these long a vowel teams in order: ai, ay, ei, eigh. This method represents a clear sequence where students learn a general concept first (vowel teams) and then apply that knowledge to specific examples in a systematically increasing complexity.
Other options, such as discussing how a word's spelling is based on its language of origin or explaining class procedures, do not exemplify sequential learning in the same way. Although teaching the letter patterns for hard and soft c and g is valuable, it is the progression from the general to specific vowel teams that showcases a more definitive order of instruction that could be understood as sequential learning.
