English language worksheet for sorting past tense verbs by their /ed/ pronunciation sounds.

Problem Overview:

The task involves sorting past tense verbs into three categories based on the sound of the ending -ed. The three sounds are:
1. /t/ (as in "worked")
2. /d/ (as in "saved")
3. /ɪd/ (as in "waited")

Solution Approach:

To solve this problem, we need to analyze each verb and determine how the -ed ending is pronounced. Here are the general rules for pronouncing -ed:

1. /t/:
- When the verb ends in a voiceless consonant sound (e.g., /p/, /k/, /f/, /s/, /ʃ/, /θ/, /tʃ/, etc.), the -ed is pronounced as /t/.
- Examples: worked, stopped, pushed.

2. /d/:
- When the verb ends in a voiced consonant sound (e.g., /b/, /g/, /v/, /z/, /ʒ/, /ð/, /dʒ/, etc.) or a vowel sound, the -ed is pronounced as /d/.
- Examples: saved, loved, cared.

3. /ɪd/:
- When the verb ends in a /t/ or /d/ sound, the -ed is pronounced as /ɪd/.
- Examples: wanted, needed, folded.

Step-by-Step Solution:

We will go through each verb and categorize it based on the pronunciation of the -ed ending.
