  2. Root Words and Endings: look, looks, looked, looking

1ST GRADE WRITING • WRITING & LANGUAGE

Root Words and Endings: look, looks, looked, looking

Learn how one little word can grow into a whole family of words!

SECTION 1

How Words Grew Families

Long, long ago, people needed simple words to talk about what they saw. They had a word called look when they wanted to see something. But people needed more words! They needed words for when their mom looks at them, or when they looked at a toy yesterday, or when they are looking right now.

Very Old Times
First Words
People made simple words like look to talk about seeing things.
Later
Adding Parts
People added little word parts like -s and -ed to make new words.
Even Later
Word Families
Now we have whole families of words that all start with the same root word!
Today
Learning Fun
Kids learn that one little word can grow into many words by adding endings!

The word look became the start of a whole word family. When we add different endings to the word "look," we can make it fit into any sentence we want to write!

SECTION 2

How Root Words Work

A root word is like the trunk of a tree. It's the main part that stays the same. Endings are like branches that we add to make new words. The root word "look" can grow into a family of four words!

1

Root Word

The main part of the word that never changes. The word "look" is our root word.
2

Endings

Little word parts we add to the end. Like -s, -ed, and -ing.
3

Word Families

Groups of words that all have the same root but different endings.
4

Making Sense

Each word in the family means something different and fits different sentences.
✦ KEY TAKEAWAY
Think of a root word like a toy building block! You can snap different pieces onto it to make new things. The word "look" is your main block, and endings like -s, -ed, and -ing are the pieces you snap on to build new words!
SECTION 3

See the Look Family

ROOT WORDlooklook(right now)"I look at you"looks(someone else)"She looks happy"looked(yesterday)"I looked outside"looking(happening now)"I am looking"The Look Family TreeOne root word grows into four different words!
Look at this word family tree! The brown trunk is our root word "look." Each colorful circle shows a word that grew from adding an ending. The blue circle shows "look" for right now. The purple circle shows "looks" for when someone else does it. The pink circle shows "looked" for something that already happened. The green circle shows "looking" for something happening right now!

This family tree shows how the root word "look" stays the same in every word. The endings change to help us talk about different times and different people. Each word has its own special job in our sentences!

SECTION 4

Building Words Step by Step

Making new words is like building with blocks. We start with our root word and add endings to make it fit perfectly in our sentences. Let's learn how each ending works!

How to build each word in the look family
WordHow to Build ItWhen to Use ItExample
lookJust the root wordWhen I do it right now"I look at the book."
looksRoot word + sWhen someone else does it"My mom looks tired."
lookedRoot word + edWhen it already happened"Yesterday I looked for my toy."
lookingRoot word + ingWhen it's happening now"I am looking for you!"

The magic happens when we add endings to our root word. Each ending gives the word a new meaning and helps it fit into different kinds of sentences. This is how one little word becomes a whole family!

SECTION 5

The Three Special Endings

The Three Magic Endings-sFor someone else"The cat looks cute"-edFor the past"I looked yesterday"-ingFor happening now"I am looking"How to Remember• -s is for HE, SHE, or IT doing something• -ed is for things that already happened• -ing is for things happening RIGHT NOW
These three endings are like magic word makers! The purple "-s" ending helps us talk about what someone else does. The pink "-ed" ending helps us talk about things that already happened. The green "-ing" ending helps us talk about things happening right now!

Each ending has its own special job! The "-s" ending tells us when someone else is doing the looking. The "-ed" ending tells us the looking already happened yesterday or before. The "-ing" ending tells us the looking is happening right now!

SECTION 6

Let's Build Words Together

Let's pretend we want to write about a girl named Emma who loves to look at birds. We need to pick the right word from the look family for each sentence!

Writing About Emma and the Birds

Step 1 — Right Now

Emma wants to see birds right now. We need a word for something I do right now.
"I look at the birds."

Step 2 — Someone Else

Now we want to tell about Emma (she is someone else, not me). We need the -s ending.
"Emma looks at the birds."

Step 3 — Yesterday

Emma looked at birds yesterday. This already happened, so we need the -ed ending.
"Yesterday, Emma looked at birds."

Step 4 — Happening Now

Emma is looking at birds right now. This is happening now, so we need -ing with "is."
"Emma is looking at birds."

See how we picked the perfect word from the look family for each sentence? Each word means something a little different and helps our story make sense!

SECTION 7

When to Use Each Word

Quick guide for picking the right word
If you want to say...Use this wordHelper words
I am doing it right nowlookI, you, we, they
Someone else is doing itlookshe, she, it, Emma, the dog
It already happenedlookedyesterday, last week, before
It's happening right nowlookingam, is, are
✦ KEY TAKEAWAY
Think of these words like different colored crayons in your word box! You pick the right colored crayon based on what you want to draw. You pick the right word from the look family based on what you want to say. Each word is perfect for its own special job!
SECTION 8

Other Word Families Work the Same Way

The look family is not the only word family! Lots of words work the same way. We can add the same endings -s, -ed, and -ing to many root words to make new families.

Other word families that work just like the look family

Learning about word families helps you become a word builder! Once you know how to add -s, -ed, and -ing to "look," you can do the same thing with lots of other words. This makes writing so much easier!

SECTION 9

Practice Problems

PROBLEM 1 — CONCEPTUAL
Which word from the look family would you use to finish this sentence: "My sister _____ at the pretty flowers"?
PROBLEM 2 — BASIC CALCULATION
What ending do you add to "look" to make a word about something that happened yesterday?
PROBLEM 3 — INTERMEDIATE
Pick the right word for each sentence: 1) "I _____ for my backpack." 2) "She _____ happy today." 3) "We _____ at the stars last night."
PROBLEM 4 — APPLIED
Write a story using all four words from the look family: look, looks, looked, looking. Your story should be about a child who lost their favorite toy.
PROBLEM 5 — CRITICAL THINKING
Explain why we need different forms of the word "look." What would happen if we only had one word "look" for everything?
SUMMARY

What We Learned About Word Families

Today we learned that words can have families! A root word like "look" stays the same, but we can add special endings to make new words. We add "-s" for someone else, "-ed" for the past, and "-ing" for happening now.

The look family has four words: look, looks, looked, and looking. Each word has its own special job in sentences. When you know how word families work, you can build lots of words and make your writing better! This helps you tell stories, write about what you see, and share your ideas with others.
