Collect various sizes and types of leaves during the Fall and use them to practice measuring. My students loved this activity - one student collected leaves at recess to do the activity again! Students need to sketch the leaf, measure the height and width in cm. and then use an App to determine the type of leaf. Focuses on measuring with centimeters.
App needed: LeafSnap - free
The App takes a photo of the leaf (make sure you use a white background) and then offers a list of possible matches. Once you select the matching leaf, you can explore information about the tree, flower, bark, etc,
