What better way to show student growth than to have them demonstrate with an animated bobblehead featuring themselves. Each students' animation could include a reflection in audio or text highlighting the way they have grown throughout the school year.
Students create a flower stem drawing in Sketchbook Express and save to the camera roll. Then, students open the image in Superimpose app and mask out the background. Save as mask png to camera roll.
Use the symmetry tool in Sketchbook Express to draw a flower blossom. Use the fill bucket to color & lines to add visual texture. Leave a circular space in the center. Open the image in Superimpose app. Layer a photo of student's head. Erase edge until it fits nicely in center. Save & reimport to erase background and save.
Use DoInk Animation app to create a composition layering the blossom on the stem. Use the keyframe button to create 4 one second stages in the bobblehead movement.
See my bobblehead animation tutorial for how to save images as a "mask png" to create transparent backgrounds, layer images in DoInk Animation app, and create the movements using keyframes.
