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

Leo wanted to have the most nails. But Asha wanted to have more nails than Leo. By Tuesday morning, Leo only had 20 nails, but Asha already had 30 nails.

At lunch on Tuesday afternoon, Leo heard Tom and Chichi making secret plans. Tom wanted to collect nails from The Construction Site, and Chichi 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 Hardware, and Mary wanted her father to bring nails from The Office.

In class on Thursday morning, Asha and Leo both had 60 nails. So they secretly decided to bring another 40 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 than anyone else. Asha had 100 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.
