Brain Teaser!

If you read yesterday's post, you'd know that we have a bit of a mystery on our hands. Why does our measurement of our combined class paper chain (743cm) not equal the combined measurements of the individual group paper chains (669 cm)?

Here are the AMAZING ideas that we shared today:

Chiara (& 9 other students agreed) - "Maybe it would be longer because there was more space in the hallway to stretch it out."
Lukas - "Maybe when Mrs. Stratford connected them and did repairs, it made it longer."
Giorgio - "It's possible that when we were carrying it out to the hallway, the chain stretched out."
Joseph - "Maybe the loops got squished and flat as we carried it."
Allie - "It's possible that the metre stick we used wasn't accurate."
Jaydee (& Ben) - "It's possible that when we used our fingers as markers, we moved them and therefore we measured incorrectly."
Ryan (& Chiara) - "Maybe the tape was sticking out and made the chain bigger."
Megan - "Perhaps the carpet made the chain wrinkled a bit and then they were shorter."
Ricky - "When we cut the links to connect all the chains, perhaps we made them bigger."
Keenen - "Maybe when we taped them, they got stretched out and longer."
Valentina (& Addison) - "When the chains were measured on the carpet, they looked a bit crooked and not straight."
