Question bank: Phoneme and Grapheme

When we are learning to read and write, we discover that each sound we make has a letter that represents it. For example, the word 'casa' has four sounds. The first sound is /k/, the second is /a/, the third is /z/, and the fourth is /a'. We want to know: What are the letters that represent these sounds in the word 'casa'? Write the letter and the sound it forms.

During a science class, 2nd-grade elementary school students are learning about the importance of recycling for the environment. Teacher Pedro decided to create a game to help students better understand the classification of recyclable and non-recyclable materials. In the game, he writes on a poster the words 'paper', 'plastic', 'glass', 'metal', 'cardboard', and 'wood'. Each word is represented by a sequence of letters that form a specific sound when pronounced. The teacher asks the students which of these words belongs to the group of non-recyclable materials, knowing that the correct answer involves identifying the grapheme corresponding to the phoneme 'n'.

In the Portuguese class, teacher Ana proposed an activity in which the students had to identify the letters representing the sounds in some words. Before starting, she explained that each sound in speech corresponds to a phoneme, which is represented in writing by a grapheme. Considering the word 'cachorro', the students should identify the number of phonemes and graphemes present in that word. Taking into account the knowledge of phonetics and spelling, how should the students proceed to differentiate the phonemes from the graphemes in the word 'cachorro'?

Observing the word 'cachorro' written, we realize that the sequence of letters 'ch' represents the same sound as a single letter in some words, like 'chave'. However, there are words like 'cabeça' where the same sequence of letters represents two distinct sounds. Considering the interdisciplinary relationship between Portuguese and Phonetics, explain how the relationship between phonemes and graphemes influences the interpretation and analysis of the meaning of words in the linguistic context of the Portuguese language.

During a Portuguese class, the teacher explained to the students the importance of understanding the relationship between phoneme and grapheme for the correct spelling of words. She showed that the phoneme 'k' can be represented by different graphemes, such as 'c', 'q', and 'k' in words like 'carro', 'quilo', and 'skate'. To practice, the teacher gave examples of words and asked the students to identify the grapheme corresponding to the presented phoneme. What is the grapheme that represents the phoneme 'k' in the word 'casa'?
