CURRICULUM

The Core Math 7 will focus on four critical areas:
(1) developing understanding of and applying
proportional relationships; (2) developing
understanding of operations with rational
numbers and working with expressions and
linear equations; (3) solving problems involving
scale drawings and informal geometric
constructions, and working with two- and threedimensional shapes to solve problems involving
area, surface area, and volume; and (4) drawing
inferences about populations based on samples.
GRADING

Grading will reflect the level of mathematical
knowledge acquired by each student. To reflect
the level of student mastery, the majority of a
student’s grade will be comprised of the
Individual Test average.

Anatomy of a Lesson
The introduction:
• gets students active
•
motivates learning
•
is often a challenge
Anatomy of a Lesson
Conceptual Development:
• Moves students from
concrete to abstract.
• When appropriate, uses
manipulatives such as
algebra tiles.
• Incorporates problembased learning.
• Uses a structured

Solving Problems with the 5-D Process
The 5-D Process is an organized method to solve problems.
The D’s stand for Describe/Draw, Define, Do, Decide, and
Declare. An example of this work is shown below.
Problem: The base of a rectangle is 13 centimeters longer than
the height. If the perimeter is 58 centimeters, find the base and
the height of the rectangle.
Describe/Draw: The shape is a rectangle
and we are looking at the perimeter.
• formal definitions.

Use the relationships stated in the problem
to determine the values of the other
quantities (such as base and perimeter).
7 + 13 = 20
8 + 13 = 21
• solved examples.

10 + 13 = 23
Use a trial value.
Trial 2:
Trial 3:
Base
(height + 13)
Do
2(20) + 2(7) = 54
2(21) + 2(8) = 58
Decide if the answer is
correct. Revise and make
another trial until you find
the correct answer.

Declare: The base is 21 centimeters and the height is 8 centimeters.
