This is a poster of inflectional endings. According to the new common core standards, this is something first graders must know. The standard is L.1.4b for first grade. I haven't looked at standards for grades 2 & 3 in depth, but I'm sure this is something those students need to know as well. Please leave a rating or feedback if you download!
