Case #101-PHONICS
The Mission
Understanding blends and digraphs is crucial for early readers to decode unfamiliar words, build vocabulary, and improve reading fluency and comprehension. Mastering these phonics patterns helps students become more confident and independent readers.

Learning Objective
"Students will be able to identify and differentiate between common consonant blends (e.g., bl, fr, st) and digraphs (e.g., sh, ch, th, wh) in single-syllable words."
1
Warm-Up: Mystery Sounds
5 min
Ask students: "Who can tell me what a 'blend' is? How about a 'digraph'?" Introduce the idea of being sound detectives for the day, investigating how letters work together to make new sounds.
2
Introducing Blends & Digraphs
7 min
Use the Slide Deck to present examples. Emphasize that blends are two consonants where both sounds are heard (b-l), while digraphs are two consonants making one new sound (sh). Use the "two friends" analogy from the slides.
3
Interactive Sorting Activity
10 min
Distribute the Sound Sort Worksheet . Work through the first two examples (frog and ship ) together. Encourage students to say words aloud and listen for the number of sounds made by the consonant pairs.
4
Guided Practice & Feedback
6 min
Circulate as students work. Ask probing questions: "What sounds do you hear in 'ship'? Is that two sounds or one new sound?" Review answers together using the Answer Key .
5
Cool-Down: Sound Check
2 min
Ask students to share one word with a blend and one word with a digraph. Briefly recap the big difference and praise their detective work!

Detective Notes: The Evidence
Blends: In words like frog , you can distinctly hear both the /f/ and /r/ sounds. The letters blend together, but each retains its individual sound.
Digraphs: In words like ship , the letters s and h combine to make one new sound, /sh/. You don't hear the /s/ and /h/ separately; they work together as a team to create a single sound.
