These heartbreaking notes from school children may make you cry

A teacher in the US has created a project for her pupils, resulting in some amazing and heartbreaking admissions from the eight and nine year olds.

In a bid to build trust between her and her students, Kyle Schwartz asked the third graders to write a note beginning with, "I Wish My Teacher Knew", which they could do anonymously if they wanted.

Many of the children come from underprivileged homes and their notes were full of sad truths. The Denver teacher decided to share them on Twitter with the hashtag #iwishmyteacherknew to encourage other teaches to use the same lesson in their classrooms.

She told ABC News, "As a new teacher, I struggled to understand the reality of my students' lives and how to best support them. I just felt like there was something I didn't know about my students."

The notes immediately went viral. Get a tissue ready...
