Master how to add the suffix -ed and discover the 4 golden base word spelling rules!
Rule 1 Just Add -ed
Rule 2 Drop Silent E
Rule 3 Double Consonant
Rule 4 Change Y to I
What is Past Tense?
Time Traveler Guide
Present (Now)
The action is happening right now.
"Today, I walk to the park."
Past (Already Happened)
The action already finished.
"Yesterday, I walked to the park."
Adding the suffix -ed signals to the reader that an action already took place!
Rule 1
Just Add -ed (Standard Verbs)
No Base Changes Needed
For most regular verbs that end in two consonants, a vowel team, or a standard ending: simply add -ed to the end!
play + ed played "We played soccer."
jump + ed jumped "He jumped high."
wash + ed washed "She washed the car."
Base word stays 100% the same: cook → cooked | help → helped | rain → rained
Rule 2
Drop the Silent E
Ends in Silent E
If the base word ends in a silent 'e' , drop the 'e' before adding -ed (or just add 'd')!
bake + ed
baked Not "bakeed"
smile + ed
smiled Not "smileed"
hope + ed
hoped Not "hopeed"
Watch out: dance → danced , skate → skated , wave → waved !
Rule 3
Double the Final Consonant
1-Syllable CVC Words
If a 1-syllable word ends in 1 Consonant + 1 Vowel + 1 Consonant (CVC) , double the last letter before adding -ed !
h o p → hopp + ed
hopped Protects short vowel /o/
s t o p → stopp + ed
stopped Protects short vowel /o/
c l a p → clapp + ed
clapped Protects short vowel /a/
hop → hopped (jumped) vs hope → hoped (wished)
Rule 4
Change Y to I
Consonant + Y Ending
If a word ends in a consonant + y , change the y to i before adding -ed !
Consonant + Y → Change to I
cry → cri + ed cried
carry → carri + ed carried
hurry → hurri + ed hurried
Vowel + Y → Just Add -ed!
play + ed played
stay + ed stayed
enjoy + ed enjoyed
Check the letter before Y: Consonant = Change to i | Vowel = Just add -ed
Rule Challenge: Which Rule Fits?
Turn & Talk
1. skip CVC
1 syllable + 1 vowel + 1 consonant
→ skipped (Double P!)
2. wave Silent E
Ends in silent 'e'
→ waved (Drop E!)
3. try Consonant + Y
'r' is a consonant before 'y'
→ tried (Change Y to I!)
4. look Vowel Team
Two vowels ('oo') before consonant
→ looked (Just Add -ed!)
Always inspect the end of the base word before writing!
Bonus: The 3 Sounds of -ed
Phonics Ear Check
/t/
Sounds like "T" after unvoiced sounds
jumped ("jumpt")
walked ("walkt")
/d/
Sounds like "D" after voiced sounds
played ("playd")
hugged ("hugd")
/id/ or /ed/
Adds an extra syllable after t or d
wanted ("want-id")
landed ("land-id")

Error: "plaied" instead of "played".
Differentiation Strategies
Support & Scaffolding
Provide letter tiles/cards for physical manipulation.
Have students highlight the base word ending before deciding on the rule.

Grade 8 Intervention Strategy
Two High-Impact Comprehension Tools
Word Analysis & Cause-and-Effect
Unlock complex nonfiction vocabulary using roots and affixes, then trace how events trigger real-world outcomes.
Strategy 1: Word Surgery Prefix + Root + Suffix Decoding
Strategy 2: Causal Chains Mapping Cause → Signal → Effect
Strategy 1: Word Analysis (Morphology)
Break It Down
When you hit an unfamiliar, multi-syllable word in 8th-grade text, perform Word Surgery :
1. Prefix
Beginning of the word
de- (down, away)bio- (life)
2. Base / Root
Core meaning
struct (build)lumin (light)
3. Suffix
Ending / Part of speech
-ion (action / state)-escent (becoming)
Example: de + struct + ion → "The process of tearing down or breaking apart"
Strategy 2: What is Cause & Effect?
Why & What Happened
The CAUSE (The Why)
The reason or trigger that starts the event.
"Dense asphalt absorbed solar heat..."
The EFFECT (The What)
The result, consequence, or outcome.
"...which caused city temperatures to spike."
Ask yourself: "Why did this happen?" (Cause) and "What was the result?" (Effect)
Signal Word Radar
Spot the Clues
Informational writers use specific transition clues to link causes to effects:
Cause Signals (Points to Why)
• Because / Since
• Due to / Driven by
• As a consequence of
Effect Signals (Points to Result)
• Consequently / Therefore
• As a result / Resulting in
• Led to / Triggered
Warning: In 8th-grade texts, the effect is often stated before the cause! Always trace the logic.

Informational Text Lexile: 545L–695L
Why Are Cities So Hot?
[1] In big cities, dark roads and roofs soak up heat from the sun. Green trees give shade and cool the air. When builders cut down trees, this deforestation takes away natural shade. Workers also construct tall brick towers that trap warm air between streets.[2] [Signal] As a result, city streets become much hotter than nearby country parks. This heat trap is called an urban heat island. The extreme summer heat [Signal] causes electric bills to spike and makes it difficult for people to stay healthy outdoors.
Part 1
Morphological Word Surgery (Roots & Affixes)
Target Word 1: construct
Prefix (con-): together / with
Root (struct): build / shape
What does "construct" mean in Paragraph 1?
Target Word 2: deforestation
Prefix (de-): remove / take away
Base (forest): trees
Suffix (-ation): action / process
What does "deforestation" mean in Paragraph 1?
Part 2
Causal Chain Map
(Trace the cause and effect from the text)
1. CAUSE (Why it happens)
Cutting down trees & building dark roofs that soak in heat
Signal Phrase: As a result

2. EFFECT (The result)

Evidence Response
What is one effect that extreme summer heat has on people in the city? Use words from the text in your sentence.

Explicit Teacher Think-Aloud Script
1. Modeling Word Surgery: "When I see the word 'construct', I break it into parts. 'Con-' means together, and 'struct' means to build or shape. In this text, workers construct buildings, which means they build them up."
2. Modeling Causal Signals: "In Paragraph 2, I spot the transition words 'As a result'. This is our causal radar signal! It proves that what happened before (cutting trees and dark roofs) directly caused the city to become hotter."
Step 1: Mini-Teach (5 min)
Present strategy slides. Emphasize prefixes, roots, and signal words in accessible text.
Step 2: Guided Read (10 min)
Partner or choral read. Circle signal words and complete morphological breakdowns.
Step 3: Map & Write (10 min)
Students complete the Causal Chain map and write their evidence response.

Strategy 1
Word Surgery: Breaking Down Complex Words
When we see an unfamiliar word, we look for three word parts (called morphology ):
1. PREFIX
Comes at the of a word.
2. ROOT / BASE
Holds the core of the word.
3. SUFFIX
Comes at the of a word.
Example: de + forest + ation → Means the action of .
Strategy 2
Understanding Cause & Effect
The CAUSE:
The reason or trigger that answers: " did this happen?"
Happens FIRST in time.
The EFFECT:
The result or outcome that answers: " happened?"
Happens as a RESULT.
