In this online activity, a child will sort items by dragging them on screen to the correct box. The boxes are labeled with words and also have an indicator icon. The instructions are provided as both text and audio, so children who cannot read yet can listen to the instructions.
This is a great activity for preschool/kindergarten, and helps children learn their colors and shapes, and to sort items by length (precursor to measuring).
You can choose what attribute to sort by, and the number of questions.
