Number Day is an annual maths-inspired event held in order to raise money to support the work of the NSPCC. This year, it is held on Friday 6th February, and schools are encouraged to take part in mathematical activities and even to “Dress up for Digits” in a number-related costume, with children making a donation to the NSPCC in order to do so.
The money raised from the NSPCC’s Number Day could go towards helping the charity run its Speak Out Stay Safe programme - which helps children understand what abuse is and what to do if they’re scared or worried - and Childline. Watch the NSPCC Number Day video below:
