Name that leaf

We went for a quick hike this weekend to Sawyer Mountain and have plans to go back again when we have more time (more than an hour before dusk). On the next trip we plan to bring our Tree Club notebook to help us identify some deciduous trees (the ones with the falling leaves right now).

We all do pretty well identifying various evergreens but the deciduous trees are much harder to figure out. There are so many tiny details to remember in order to tell the differences among them.

The leaf that prompted us to return with our tree identifying notebook. We guessed it was from a maple tree but needed to consult the book at home to figure out it was a sugar maple leaf.

Do you have a trick to help identify certain types of leaves? We know the white pine tree one (5 needles = 5 letters in w-h-i-t-e). We'd love a few other tips to make it easier for us to remember if you have 'em.
