Subject
Area: Mathematics
Grade
Level: middle school
Overview:
The students will gain profound
understanding of the meaning of addition and subtraction
of integers.
The lesson begins with a concrete model and scaffolding
is gradually released until the concepts can be used
abstractly.
Students start the lesson using tile spacers as manipulatives,
tapping into the kinesthetic intelligence. The students
advance to drawing models on whiteboards, permitting
the teacher to check for understanding. Once the class
progresses to paper, the students now have a tool to
construct meaning when rules are forgotten.
Finally the students advance to abstract algorithms.
The final assessment is to apply this acquired knowledge
in solving a word problem.
Standards:
7th grade
Number Sense 1.2
Mathematical Reasoning 3.1 ,3.2
