Are you teaching a combined 2-3 class?
This is a fun activity to use anytime (especially at the end of the year) to engage the students with the science vocabulary for the Animals Growth and Changes unit in Grade 2 and the Plants unit in Grade 3.
The cards for both are differentiated with the plant background or the animal background so students in grades 2 and 3 can easily see which cards are designed for their unit of study.
You can have this as a whole class activity or as a word work center.
Each set contains 24 vocabulary cards (total of 48 vocab cards) and the response sheet.
