Keeping them engaged by making and selling dog cookies (proceeds go to local rescues) gets them working with peers and creating new friendships. \r\n\r\nSeeing my students making connections has helped motivate them to come to school which in turn helps build their self esteem. \r\n\r\nThank you all!","fullyFundedDate":1723695319548,"projectUrl":"project/the-barkery/8660358/","projectTitle":"The Barkery","teacherDisplayName":"Ms. Ratchelous","teacherPhotoUrl":"https://cdn.donorschoose.net/images/placeholder-avatars/272/teacher-placeholder-5_272.png?auto=webp","teacherClassroomUrl":"classroom/8992108"},{"teacherId":9633155,"projectId":8576766,"letterContent":"Thank you for donating the money for my printed materials for my Reading Intervention class at the high school level. The students have enjoyed reading about science-oriented subjects like the latest astronauts going into space or to the debate of if students in public schools should be required to wear school uniforms. Reading about current events which describe an event that is actually going on in the world helps remedial reading students gain important background knowledge about that particular subject matter. \r\n These wonderful lower level reading materials are of high interest to my high school students and they really like reading them aloud together in a group first and then enjoy discussing them afterwards. Many of these students lack background knowledge in the subject areas of science and social studies so this additional resource is valuable for them to gain more knowledge in a highly interesting way. The actual real pictures from space or the scene of a protest about school uniforms makes it feel \"real\" to them.\r\n Thank you again for donating to my remedial reading high school classroom.\r\n These resources were much needed and valuable for the success of my students improving their reading levels.","fullyFundedDate":1723468018966,"projectUrl":"project/printed-reading-materials-for-mental-hea/8576766/","projectTitle":"Printed Reading Materials for Mental Health","teacherDisplayName":"Mrs. Gretchen Marino","teacherPhotoUrl":"https://cdn.donorschoose.net/images/placeholder-avatars/272/teacher-placeholder-8_272.png?auto=webp","teacherClassroomUrl":"classroom/9633155"}],"pageName":"schoolpage_44078","usesDonorsChoose":true,"infoPageType":"school","demographicsInfo":{"numStudents":673,"numTeachers":70,"percentFrplEligible":38,"percentAsian":5,"percentBlack":2,"percentWhite":65,"percentIndigenous":0,"percentLatinx":21,"showFreeAndReducedPriceLunchInfo":true,"showDemographicsInfo":true,"sourceTooltipString":"the National Center for Education Statistics","gradesServed":"9 - 12","studentTeacherRatio":"9.6:1","demographicsDataSource":"MDR School","equityFocus":false,"titleOne":false,"metroType":"SUBURBAN","ncesMetroType":"SUBURB_LARGE"},"inStateSupporters":77.4,"schoolId":44078,"financialInfo":null,"twitterShareText":"Learn more about Mark T Sheehan High School on @DonorsChoose:","schoolName":"Mark T Sheehan High School","canonicalPageUrl":"schools/connecticut/wallingford-public-school-district/mark-t-sheehan-high-school/44078"}
