50 The History of the Earth: Supplemental Guide 2B | The Earth Inside-Out, Part I
Earth’s Crust (Instructional Master 2B-1) 15 minutes
Show image 2B-1: Living things and Earth’s crust- Tell students that the tree and dog are on the crust, the roots
and soil are in the crust, and the birds are above the crust.
Review with students the meanings of the prepositions on, in,
and above as necessary. - Ask students to think about what they learned from the read-
aloud about the crust of the earth. Have students brainstorm
things that they heard about in the read-aloud or have observed
above the crust. Record students’ responses on chart paper, a
chalkboard, or a whiteboard. Tell students that you are going to
write down what they say, but that they are not expected to be
able to read what you write because they are still learning all the
rules for decoding. Emphasize that you are writing what they say
so that you don’t forget. Tell them that you will read the words to
them. - Follow the same procedures for fi lling in “on the crust” and “in
the crust.” - Once the chart has been completed, read it to the class.
- Have students make their own drawing on Instructional Master
2B-1 that shows things on, in, and above Earth’s crust. Then
have students label what they have drawn using the sound-
spelling correspondences taught thus far.
