The purpose of 3 Part Cards is to enrich and enlarge a child's vocabulary, and to aid in the classification of the environment. The cards are meant to give a small introduction to the child by opening their minds so they are internally driven to find out more about a presented topic.
This full set contains 18 sets of control cards, image cards and labels along with a display card in .pdf format. They can be printed on card stock, trimmed and then laminated for years of use.
I use these sets to introduce my Upper Elementary students to an artistic movement or time period through an art shelf display in their classrooms. The larger 8.5" x 11" card is displayed on a small easel and the individual three part cards are used as extension work outside of their art instructional time. The students then use these cards as inspiration for their own art pieces.
