Third graders examine two-dimensional objects and create a 3-D image of the object. They make models of the Taj Mahal and buildings in Delhi.

Students create paper masks linking the function and purpose of masks in the past, with modern life.

In this volume worksheet, students create different sized cubes and compare the sizes by pouring sand from one cube into another. Students follow 4 directions and reflect on their findings.

In this problem solving worksheet, students analyze a row of pictures of various animals to determine which creature is different from the others pictured.
