This is a group activity and you can use it in a center. The Venn diagram is made in a large construction paper. Trace the circles with a big plate. The students sort and glue the pictures.
The mobile is made in yellow and blue construction paper.
Cut a large construction paper in four. Fold one piece of yellow and one blue in half. Cut along the fold to a little more than half.
Insert between each other. (I tape the blue and yellow papers to hold them on place). Write day and night on top of each square, sort and glue the pictures.
