Question 66

D) Train, trail, tree, try

The best set of words to use when teaching consonant blends is "Train, trail, tree, try," as each word begins with a distinct consonant blend that can effectively illustrate the concept to learners.

A) Street, chase, phone, shop

While "street" and "shop" contain consonant blends, "chase" and "phone" do not begin with consonant blends, making this set less effective for teaching the concept. A focus on consistent examples is key in teaching consonant blends.

B) Know, new, now, knew

None of the words in this set contain consonant blends; instead, they focus on vowel sounds and silent letters. This makes them unsuitable for teaching consonant blends, as they do not provide any relevant examples of the concept.

C) Speech, spoke, spell, grasp

This set contains some words that have consonant clusters, such as "spell" and "grasp," but does not consistently represent the concept of consonant blends at the beginning of the words. Therefore, it is not the best choice for teaching this specific phonetic concept.

D) Train, trail, tree, try

This option is optimal as all words begin with consonant blends: "tr" in each case. This consistency provides clear examples for learners to understand and practice the concept of consonant blends effectively.

Conclusion

Option D is definitively the correct choice as it provides a uniform set of words that all feature consonant blends, essential for teaching this phonetic concept. In contrast, the other options either lack consonant blends or include irrelevant sounds, making them ineffective for the intended educational purpose.
