As we all know full well, every classroom, regardless of the grade or grade level combination it contains, is more effective and stimulating, when it contains a diversity of materials and ideas for daily use; hands on, eye catching, thought provoking,cross curricular, motivational STUFF.
Organizing any classroom so that it is visually and intellectually stimulating, is a challenge by its very nature. My thinking is that especially for new teachers starting their classroom careers a list that contains time tested materials that they can CHOOSE FROM as they suit their teaching style, would be a good addition to the TPT site.
Over my 22 years of classroom teaching ( 20 of which were in multi-age classrooms) I had a such a list I developed and used each year regardless of the age or grade(s) of the students I worked with.
Part of the beauty of working with youth is that you never REALLY know what will spark their interests.
This is a list of 70 of the things I found, made my work day with my students, a success.
