Final answer:
The tasks focus on identifying vowel sounds and letters, understanding word structures, and applying rules for verb usage in English. Students work with letter sounds, vowel identification, word transformation, and sentence completion.
Step-by-step explanation:
The question involves several tasks related to the English language and word structure. First, students are required to identify and underline the letters that represent the sound [b] in various words. Examples provided include 'able', 'scribble', 'resemble', and so on. In 'able', the letter b would be underlined since it produces the [b] sound.
Next, students must fill in the blanks with vowels. The four letters that are always vowels are <a>, <e>, <i>, and <o>. Furthermore, students must underline each vowel in the provided words to understand vowel placement.
Additionally, word changes are performed where students work with words ending in <tle> or <ttle>, paying attention to the correct spelling which might require single or doublets. An example is transforming 'battle' through a series of steps that alter consonants and vowels.
Finally, in another task, students select the proper verb to complete sentences, recognizing subject-verb agreement and correct verb tense.
Understanding the structure and sound of words is a fundamental aspect of English, and these exercises are designed to build proficiency in these areas.
