April Fools Joke

[Zoeyclash]

Hi all,
This is not an AIBU but I'm posting here for traffic if that's ok with you all. I'm a primary school teacher and I'm working online with my y6 class every day through an educational platform. I'd like a play a light hearted April Fools joke on my class as I know they'd enjoy it, but I'm stuck for ideas. Do any of you helpful mumsnetters have any suggestions of a simple prank I could play on them online? Thanks every one!

YABU.

Give them a test that's "easy" but it's really hard. Or put a massive book down and tell them that's their homework. Or make them all do the lesson blindfolded and tell them it's really important they don't peek and you'll tell them why afterwards, then tell them there was no point, it was just an April Fool.

There's a meme going round with Boris Johnson staring that schools opening tomorrow and holidays and weekends have been cancelled. But maybe that's not funny if it's actually believed.

Some sort of word definition matching?

Scientists have found an extra day of the week although thatmwoiod make no difference to them at the moment!

This lets you make your own news story with BBC news logo. Looks convincing enough to fool some 10 year olds

There was someone on another fool's joke thread suggesting parents should tell kids that the teacher will be staying for a week with students to help them with learning😂

Say the teachers have said school uniform needs to be worn at home during school hours?

New SATS test coming out on housework, dishwashing, ironing, taking bins out etc etc and they need to get practicing immediately for assessment after virus has gone

...........They need to keep a scrapbook of evidence for everyday

What @StoneofDestiny said

I'm giving all mine a detention (yr8).

There is that "exam"/"test" where it tells you to read all the instructions, then gives you some really hard stuff to do, and then at the end says "Don't do any of that stuff, just put your pen down and cross your arms". You could maybe work out something funny along those lines?

I saw a really funny one on YouTube where the teacher gave a spelling test but all the words were completely made up. He even gave the definitions of the words after but the kids obviously couldn't get a single word right as there were silent letters etc.
