In class on Monday morning, Teacher Grace gave grade 5 a challenge: collect nails from the environment.

Leo wanted to have the most nails.

At lunch on Tuesday afternoon, Leo heard Tom and Chichi making secret plans. Tom wanted to collect nails from the The New School.

In class on Wednesday morning, Asha heard Maggie and Mary making secret plans too. Maggie wanted to buy nails from The Office.

In class on Thursday morning, Asha and Leo both had 60 nails on Friday morning to win the challenge!

On Thursday night, Leo followed Tom to The Construction Site, and Asha followed Maggie to The Hardware.

In class on Friday morning, Asha and Leo both had more nails and Leo had 120 nails! But that's when things got ugly.

Teacher Grace said Mary's nails were not from the environment. That's when Chichi said that he saw Leo sneaking around The Construction Site with Tom. Then Leo said he saw Asha leaving The Hardware with Maggie!

Teacher Grace decided she had heard enough. Mary and Chichi and Leo and Tom and Asha and Maggie were all disqualified!

And that's how Sasha won the challenge with only 7 nails that she collected in The Market.
