AIM: How can we identify and combine like terms?
HW: Log into Jupitergrades; Watch the video through the links below. .
There will be a test this Friday, March 4 (3/4). The test will include material from unit 4, with a focus on more recent material. Topics include:
· Combining like-terms and simplifying expressions
· Distributive Property
· Solving One, Two, Multi-step equations
· Writing (and solving) equations from word problems
· Linear relationships
· Rate Tables
· Writing equations with independent and dependent variables
· Rates of change
(Pictures of oranges and apples) How many oranges are there? Apples?
Classwork: The point of today's Do Now was to reinforce the fact that when asked how many oranges there were, students added up the oranges and did not include the apples. Combining like terms is like apples and oranges. Terms that belong together can be added or subtracted--using their respective coefficients. Terms that are not "like" cannot be combined and must stay individualized. We worked through several model problems, partner problems, and small neighborhood problems. Students used strategies such as circling like terms, then performing the math on the coefficients. Students can also reorder the expressions, using the commutative property of addition, if they prefer to simplify in that manner.
