I have spent way more than I wanted to already this year. Yet, I still wanted individual reading bins for each student. The cheapest I have found was about $100 for a classroom set. This was pretty cheap compared to other places but still way more than I want to spend this year. Yesterday, I went to IKEA and found packages of 5 of those pictured below for $1.49. I easily got my whole class a set for under $10. I figure that these won't last a whole school year but I am ok with that. I will get a set of plastic bins next year (unless this year is a big hit).
As a bonus, I decided that since they are stark white, I will have my students decorate them with markers, crayons, and stickers. I figure this will give the students ownership in their bins. They can keep them at the end of the year. I hope that personalizing these boxes will help get the students excited about reading.
