This is a short list of words found beginning in second grade textbooks. Ask your second grader if they know what the word means. Focus on the landforms, such as peninsula, lake, plain, plateau, box canyon, etc. Have your student assist, based on their comprehension level. You can also look through a magazine and use a picture that shows a coastline with trees, a meadow with mountains behind it, etc, and have the student draw a map of it.
First grade can do that, too.
Do the map key with your child, placing symbols in it for the landforms you need. Print out this page so your child will have a map key they can copy. Have the student write down what they think the word means by providing a definition. Next, have them look up the word in the dictionary. For one day's work, select ten words.
