text: Reaching out: Third-grade teacher Kyle Schwartz devised a lesson plan last month, which has spread to classrooms across the nation via Twitter . A third-grade teacher in Denver, Colorado has sparked a sensation on Twitter, after asking her students to open up about their personal struggles. Kyle Schwartz has been a teacher for three years, and says that many of her students at Doull Elementary School come from underprivileged backgrounds, with 92 per cent of the student body qualifying for free or reduced lunch. Seeking to understand a bit more about their lives, Schwartz last month thought up a lesson plan called 'I wish my teacher knew...' She asked all for he children to write down one thing they wanted to tell her, but wouldn't normally in the classroom situation and the results were heartbreaking. The first note that Schwartz shared on twitter was from a student who said they didn't have pencils at home to do their homework. That note especially touched Schwartz. 'I care deeply about each and every one of my students and I don't want any of them to have to suffer the consequences of living in poverty, which is my main motivation for teaching,' Schwartz told ABC News. Another, spoke about missing her father, who was deported back to Mexico six years ago. Hoping to learn more about her students' personal struggles, Schwartz asked them to answer the qestion 'I wish my teacher knew...' on a piece of paper and turn it in to her anonymously or share it with the class. Schwartz sais she found the above note from a student who didn't have pencils at home to do homework especially heartbreaking . Alone: After trying out the lesson plan, Schwartz says she not only learned more about her students, she saw a change in how they interacted with each other. For example,  a group of girls invited one student to play at recess after hearing in class that they felt they had no friends . Heartbreak at home: One student wrote about missing her father, who was deported six years ago back to Mexico . Language barrier: Another student in Schwartz's class wrote about a challenging aspect of being bi-lingual . Busy parents: Schwartz shared many of these notes on Twitter, and soon teachers across the nation started trying out the lesson themselves and posting their own results online . 'I wish my teacher knew I don't have [a] friend to [play] with me,' another note read. Schwartz said that she gave her children the option to answer the question anonymously, but found that most signed their name and were even willing to share their story with the class. After sharing some of the notes on Twitter, Schwartz said she started getting responses from teachers across the nation who tried out the lesson. 'It's hard to stay asleep at night': Rebecca Shoniker, a middle school teacher in North Carolina, shared these responses from her class on Twitter . 'I think it caught on so fast because teachers are highly collaborative and freely share and explore resources,' Schwartz said. 'In the end, all teachers want to support their students, and #iwishmyteacherknew is a simple and powerful way to do that.' Since trying out the lesson plan, Schwartz has not only learned more about her students, she has seen a change in how they interact with each other. 'After one student shared that she had no one to play with at recess, the rest of the class chimed in and said, 'we got your back.' The next day during recess, I noticed she was playing with a group of girls,' Schwartz said. Stressful: Dawn King, a fourth grade teacher, shared this letter from a student who was worried about a sick parent . Sadness: Another student in King's class wrote about a fear of having depression. That student was open enough to share those fears with a parent . Bullied: Mary Lou Shuster in South Portland, Maine, shared this note about a student who is being bullied .
