Many of the sharp and flat products I found on TpT went a little too deep for my students that I only see once a week. I wanted to scaffold the material so they could process it in smaller doses. Before we talk about key signatures at all, we can just talk about what a sharp does and what a flat does. It does have a hint for continued learning to spark curiosity. Students will not feel that they have learned everything they need to know about sharps and flats.
This product is ideal for 3rd - 5th graders, but can be used with early readers and teacher directed lessons with read aloud.
