This science workbook is a great tool for teachers to teach a unit on metamorphic animals as well as non-metamorphic animals and their differences. The lessons focus on the life cycle of the butterfly and the frog and how non-metamorphic animals change only by size.
The workbook is 13 pages of fun activities in which students will fill in the blanks, and colour the drawings. A full teacher answer key is attached.
In British Columbia, it is in the Science curriculum for grade 2: "Living things have life cycles adapted to their environment."
