Maths Reasoning - Was Peter right? What did he mean?

On Thursday 16th November, Peter Kay was on the radio with Chris Evans. Here's a conversation they had. Available for 30 days (listen at 41:15)... 

Peter Kay (PK): You're lying in bed now thinking, I'll get up after this song. Round it up... What is it now? 7 what?
Chris Evans (CE): 7:12.
PK: Wait until 7:15.
CE: Yes, yes...
PK: Don't get up on an odd number.
CE: Go crazy.
PK: Wait until 7:15. When it's 7:17, wait until 20 past. 
CE: Is that what you do?
PK: You gotta round it up. You can't just get up mid numbers. 

So, Peter said to not get up at 07:12 and wait until 07:15 as he doesn't like to get up on an odd number. What's wrong? What was he intending to say? How can that be re-worded, but more mathematically accurate?

Preposition in the Classroom

Heard of Elf on a shelf, right? So, here's something inspired by it...

Print and laminate the word 'preposition'. Each morning, put it on, under, behind, inside something and the class need to find it, and then describe where the word is, using a preposition...

On the window, under the chair, next to the board...

Welcome to Your Classroom

So this happened between us two many years ago and I've kept it going since...

After three years of teaching in Year Four, I was told I'd be moving to Year Five. I wasn't thrilled by the prospect, however, it turned out to be one of my most successful and rewarding years in the classroom to date. 

When I (Liam) moved into Year Five, I took over the classroom previously occupied by Dan. On the day I went into the classroom to sort it out, there was a note on the whiteboard. "Mr. M., Welcome to Year Five. You'll be awesome! Dan". It meant a lot.

Since then, I've moved classroom (but not year group) many times. And, I've always left a welcome message for the new incumbent of my previous room. 

Maybe you could start doing it too?
