Assignment Overview

Welcome to SENTENCE SAFARI - where we'll track down writing mistakes
like a wildlife expert tracks animals!

Clear sentences help us share amazing facts about animals. But sometimes
our sentences have problems that make them confusing to read.

On this safari, you'll hunt for:
- FRAGMENTS (sentences missing important parts!)
- RUN-ONS (two thoughts that collided!)
- AGREEMENT ERRORS (subjects and verbs that don't match!)
- TENSE SHIFTS (confusing time jumps!)

Grab your binoculars and let's explore the wild world of sentences!
Each step builds your skills, and by the end, you'll be a sentence expert!

From tiny insects to massive whales, our planet is home to millions of incredible animal species. Each one has adapted special abilities to survive in its environment - whether that's the deep ocean, scorching desert, or frozen tundra!

Step 1: Identify Errors
Read each sentence below. Mark whether it is CORRECT, a FRAGMENT, RUN-ON, COMMA SPLICE, AGREEMENT error, or TENSE SHIFT. Then briefly explain.
1. Cheetahs runs faster than any other land animal. 2. The elephant uses its trunk to drink water and grab food. 3. Swimming gracefully through the coral reef. 4. Penguins live in Antarctica they huddle together to stay warm. 5. The wolf pack hunted all night and catches a deer at dawn. 6. Dolphins communicate using clicks and whistles.
Answer Key
1. AGREEMENT - "Cheetahs" is plural, should be "run"
2. CORRECT - Complete sentence with matching subject and verb
3. FRAGMENT - Missing subject (who is swimming?)
4. RUN-ON - Two sentences stuck together
5. TENSE SHIFT - "hunted" (past) jumps to "catches" (present)
6. CORRECT - Complete sentence with subject and verb
Step 2: Fix Fragments
Each sentence below is a fragment. Rewrite it as a complete sentence on the lines that follow.
1. The colorful parrot with bright red and blue feathers. 2. Sleeping for twenty hours a day like most cats do. 3. Because polar bears need thick fur to survive the cold. 4. Jumping from tree to tree in the rainforest canopy.
Step 3: Fix Run-Ons
Rewrite each run-on or comma splice as two correct sentences (or join them with a coordinating conjunction or semicolon).
1. Sharks have been around for millions of years they are older than dinosaurs. 2. Butterflies start as caterpillars they transform inside a chrysalis. 3. Owls hunt at night they can see in almost complete darkness. 4. Bees make honey it takes visiting thousands of flowers to make one jar.
Step 4: Subject-Verb Agreement
Rewrite each sentence so the subject and verb agree.
1. The pack of wolves hunt together to catch large prey. 2. Each of the baby birds need food from their mother. 3. The herd of elephants travel many miles to find water. 4. Everyone at the zoo love watching the playful otters.
Step 5: Fix Tense Shifts
Rewrite the paragraph below in consistent past tense.
Yesterday, we visited the wildlife sanctuary to see the rescued animals. The zookeeper shows us a baby owl that fell from its nest. She explained how the sanctuary helps injured animals heal. We watched as she feeds the owl some small pieces of meat. The owl looked at us with its big eyes and makes a soft hooting sound. It was an amazing experience that we never forget.
