### About

I have completed my degree in mathematics and education and have been teaching maths and English for a couple of years. I am an aspiring Secondary school maths teacher and am just about to undergo my training in the educational field. I am very eager to make learning an enjoyable experience with good results. Please feel free to get in touch if you feel your child could do with some extra help to keep on top of their school work over the summer period and during the term time. I have been teaching students between the ages of 5-18 years for the past 3-4 years as a tutor. I have mentored in a couple of secondary schools in south London and in Hastings for 2 years whilst studying at university. This has enabled me to understand how different students approach mathematics and English and adapt my teaching methods to suit each individual. I understand that often students are not keen to engage in a classroom setting and find it more comfortable to learn with less people around them and I am willing to adhere to students' needs and wants. I have experience with working with students who struggle to focus in mainstream environments (especially with students who suffer from ADHD and Autism). My aims for teaching mathematics is to make it less intimidating for students and for teaching English, to make it less of a chore to write essays and more of a way to express ideas and emotion; thus achieving good results.
