In these engaging activities children use collections of small interesting objects, "treasures," in an innovative series of mathematics activities. Working with treasures provides fresh ways for students to learn and grow, bringing many important science and math skills to life. Six main activities are outlined for teachers with clear step-by-step directions, complete with assessment outlines and "going further" suggestions. The activities build upon one another to allow students to develop their abilities in many areas of math and science. Challenges that require careful observation, sorting and classification, logical thinking, graphing, and analyzing data are woven throughout this unit.

The correlation of each activity with computer programs and with children's literature is excellent. The inclusion of a section on literature connections provides a wonderful resource. . . . Treasure Boxes is a well-designed, teacher friendly program. I highly recommend it as a supplemental resource in early-childhood and elementary classes."- Teaching Children Mathematics , March 1999
