a. Objective The student will be able to use their textbook to answer questions about slope.
RST.9-10.9. Compare and contrast findings presented in a text to those from other sources (including their own experiments), noting when the findings support or contradict previous explanations or accounts.
b. Model Describe to students how to come up with answers about a chapter reading. QAR - Question-Answer Relationships In the Text:
Right There – The answer is “right there” in the text. The key words in the question and the words used in the answer are most likely found in the same sentence.
Think and Search – The answer is still in the text but it may not be in the same sentence as the words from the question. You have to consider what you read in the text to answer the question.
In Your Head:
Author and You - The answer is not found in the text. You have to think about what you know and what the author states, then figure out how they both fit together.
On Your Own - The text has the same idea as the question, but to come up with the answer you have to think and create. The author can't help you much. Think about the question and use what you already know and read to answer it.
c. Guided Practice Have the class work in groups of two to four students to answer the following questions. 1. What is the formula for the slope of a line? (Right There) 2. How do the slopes of perpendicular lines relate? (Think and Search) 3. What is the slope of a parallel line to the line depicted by the equation: y=2x+3? (Author and You) 4. Draw a line through two points. Use what you know to draw another line perpendicular to this line. (On Your Own)
d. Independent Practice Create a word problem that uses the concepts found in the reading about parallel and perpendicular lines but is not found directly in the book. What kind of question is this considered in the model above?
e. Assessment
For assessment purposes, walk around each group and see how they try to solve the problems. Check for understanding of the process required for each type of question.
