Native English teacher - children's classes

We are a language school in Madrid looking for a native English speaking teacher to fill 3 classes in the afternoons on Tuesdays, Wednesdays, and Thursdays (any one, or all three). 

1. One class is a 1-hour class of a group of 4 children, all about 6-7 years old. These classes are meant to be fun, dynamic, light, and play-based. They are Wednesdays from 6:00-7:00pm, near Metro: Canillejas (line 5).

2. Another class is a 1-hour class with one 10-year-old boy, mostly schoolwork support and listening comprehension and speaking practice. These classes are Tuesdays from 6:00-7:00pm near Metro: Nuevos Ministerios (line 8, 10, and 6)

3. Another class is a 1-hour ONLINE class with a 15-year old girl, helping with school support and homework. In the future she may need support preparing for an official exam. These classes are Thursdays from 5:00-6:00pm.

Previous experience working with children required. 15€ per hour.
