Help autistic child become happy in school

Hi I my daughter Arya is 7 years old. Arya is autistic but wasn’t able to gain a place in a SEN school and is struggling in a main stream set up both from a learning perspective and also social. We are looking to raise fund to provide a tablet/laptop to help Arya communicate easier with bit teachers and her peers. Not only would this help in school but it would give us the ability to carry on with her education at home and hopefully prevent her falling too far behind her peers. This would help Arya immensely as she has already become aware of the differences between her and others in her class but struggles to understand why. Having this extra way to express herself while learning at the same time will hopefully help Arya gain more confidence in herself and in time to make friends as at the moment she spends most playtimes alone and doesn’t have any friends outside of school as she struggles to communicate with others. Any help would be much appreciated and thankyou for taking the time to read this.
