Why your support counts

Over 80% of the NSPCC's income comes from those who choose to give to them including schools, the NSPCC simply couldn’t keep its vital services running without the support of people like you. Every pound raised will all add up.

Everything the NSPCC does protects children today and prevents abuse tomorrow.

The NSPCC need support more than ever. By raising money, we can help fund vital services such as Childline – the helpline that’s always there for children and young people whatever their problem or concern.

On average, a child contacts Childline every 45 seconds.

The money raised could also help the NSPCC reach more schools with the Speak out. Stay safe. programme – giving children the knowledge and confidence to speak out about anything that is worrying them, including abuse, so they can get help.

£4 could help answer a child's call to Childline.

£28 could pay for a trained practitioner for one hour, supporting parents and families in caring for their children.

£90 could pay for our Speak out. Stay safe. programme to reach every child in a primary school class of 30 children.

What could children and teachers dress up as for NSPCC Number Day?

Your school might be encouraging children and staff to dress up for Number Day. If you’re a bit stuck on what to wear, here are some ideas:

Mathematical equipment: things like calculators, dice, dominos, clocks, playing cards can be really fun - especially if you can get a whole group of you in the same outfit!
Characters from books work well and can be doubled up for World Book Day as a cost-effective idea: Thing 1 and Thing 2 from The Cat in the Hat, Tock or The Mathemagician from The Phantom Tollbooth for example.
Characters from TV or films: The Numberjacks, The Numberblocks, Thomas the Tank Engine (& friends) with their numbers on.
Famous Mathemeticians: Alan Turing, Ada Lovelace, Pythagoras, Fibonnaci (particularly great for Year 6 children/teachers who might be studying some of these people).
No-fuss ideas include wearing a football strip with a number, or simply drawing numbers or calculations on a white t-shirt!
