Miss Pratchett needs Year One's help!!!

 Last night I received and email from the lovely Miss Pratchett. She needed our help. This is what it said. 

So this morning I showed Year One the email and they jumped at the task eagerly. 

Afterwards we emailed her a reply, with three attachments.

These were the attachments:

 Nathan's working out.

 Jennie's working out. 

And of course the said video of us working out how many pencils there would be in 10 packs of 10 pencils.

We can't wait for her reply to find out if we were helpful.
