Please help me <br>thank you ​
kifflom [539]

What its saying is:

for the chain chart: list a dangerous weather phenomonon you experienced and list words that specify the weather condition you experienced. For example:

you experienced: hurricane Catrina

Details: Had wrecked my house, was very scared then, other people were scared aswell, etc.

( Note that these details come in handy later for the next part.)

The next part wants you to organize the parts of the story kevin made about his hurricane. as a cheat key, its: 2, 1, 3, 4.

Drafting: Its asking you to make a sentence that describes how you felt during that time. You have to use the I before anything else in order to count for the grade if there is any grade given for this lesson.

The next part just wants you to write a story on teh event that you experienced, in this case the hurricane or other weather condition you have brought up.

Revising and proofreading:

were > was

think > thought

was > we

ever > remove this word

The last part just wants you to check off everything, like a grocery list.

Hope this helped!
