TEKS: Reading & L.A.: (14)
Science: (4)A
Reading Strategy: SQ3R: The students will survey the information skimming it over,
and noting main ideas. Next, students will turn each heading into a question.
They will then read the selection, and try to answer the question. Then students
recite the answer to questions either orally or by writing. Finally, student review
what they have read, and any answers found during reading. If the student had
not already written down the answers, they do so at this point.
Additional Activity: Students will use magnifying glass to examine different types of
dinosaur teeth, and figure a way to classify them.
Teacher Tidbits: You could either use a book of teeth at a station, or you could print a
worksheet of teeth and have the students cut out each one and examine it.
