Chestnut Street primary school in Ruskington went number crazy for the NSPCC charity.
On Friday children engaged in many activities to test their maths abilities.
Maths co-ordinator Sally Darling explained that Reception childreen made shape monsters and Year 1 went on a shape hunt.
Year 2 focused on units of measurement, Years 3 and 4 tested how far a paper aeroplane would fly as well as investigating whether the size of a ball affected how far it would travel when thrown.
Years 5 and 6 had the exciting task of planning an amazing holiday on a set budget given to them.
Mrs Darling said: “We raised over £160, that will support a very worthwhile charity.
“In the afternoon the children shared what they had learned with the rest of the school, whilst dressed in a variety of number costumes. A mathstastic time was had by all!”
