Classroom Activity (BLM 7)


Name ___________________________________ Date ____________________________________

Hawaiian AdventureMom told my sister Ava and I that we could do whatever we

wanted to on spring break. We’re not used to getting choices like that, so

we were very excited! Hawaii, here we come! Before we left, we collected

data and made lists: lists of what to bring, lists of places to visit, lists of

activities—that kind of thing.

Finally, we arrived at our vacation spot, our lists in hand! I wanted

to cook while we were there, using as many fresh Hawaiian ingredients

as possible. The first day, I grilled tuna and made a salad with tomatoes,

mangos, pineapple, shrimp, and sweet potatoes, served on banana

leaves. While I did that, Mom and Ava went freshwater fishing. They were

surprised to learn that there are places in Hawaii where you can catch

trout and catfish—Ava’s favorite fish!

One day we went to the zoo. We watched the pink flamingos as

they napped while standing on one leg. Then we went to watch the

kangaroos jump around with their joeys in their pouches. We also saw

an insect display with unusual larvae.

What else did we do? One day we visited a memorial at Pearl

Harbor where many heroes lost their lives during World War II. We also

went to a concert one evening. Ava thought the sopranos sounded

awesome. Another day we found some vertebrae on a quiet beach.

We thought it might be from a whale or some kind of fish.

Snorkeling, visiting the aquarium, building sandcastles on the

beaches, eating shaved ice—we crossed everything off of our lists.

I’m so happy that Ava and I got to choose our vacation!

Challenging Plurals

Some words ending in o add -s to form the plural: studio + s = studios memo + s = memos

Some words ending in o add -es to form the plural: veto + es = vetoes potato + es = potatoes

Some words ending in o add either -s or -es to form the plural:

buffalo + s or es = buffalos, buffaloes tornado + s or es = tornados, tornadoes

Some words keep foreign spellings of the plurals: a to ae us to i alga algae radius radii larva larvae stimulus stimuli

um to a is to es medium media axis axes bacterium bacteria diagnosis diagnoses
