I've made some french versions of my leaf identification handouts and worksheets. They are now available here: https://www.teacherspayteachers.com/Product/French-Leaf-Identification-Worksheets-Fiches-didentification-des-feuilles-7123234
These are great for fall tree walks and for french language, science and art activities. I have enjoyed using them as part of an interdisciplinary approach to the Ontario Science curriculum. Students collect and identify leaves. Then they complete a scientific illustration about their leaf. After that we learn about the communities and habitats of the trees and the species that live around our school.
