August 18, 2010
In today’s training, we will…
• engage in activities and in-depth discussions
that promote higher level thinking skills
• connect each standard in relation to
equations with an example
• be aware of items that prior grade levels
have learned

How do we make sense of teaching deeply?
Provide a “focused” curriculum.
Collaboration of vertical and
horizontal teaching
Explore deeper content based
knowledge. Think of a swimming
pool. Most people stay in the
shallow end…we now need to
venture to the unknown depths
of knowledge.
Develop connections from 6th
grade math through pre-calculus
Emphasis of higher level
thinking- analysis, evaluation
and synthesis
Teaching For Depth
 Equations
as an example standard linked
through the grade levels
 Fair
game review through models and visuals
 Use
cooperative learning strategies to
introduce or remediate equations
 Represent
equations using models, vocabulary,
pictures, and real world situations
 Lead
students to mastery level not
memorization
What is Rigor?
What Rigor is Not:
a measure of the quantity of
content to be covered.
a special program or curriculum for
select students.
about severity or hardship.
only about higher-order thinking.
Rigor
Rigor is quality instruction that
focuses on the depth of the learning
not the breadth. It’s not more work;
it’s meaningful, respectful work that
requires the student to think deeply
and critically to accomplish the
assigned tasked.

6th Grade Equation Strategies
Solving one-step
algebraic equations
NGSSS: Equations(6th)
MA.6.A.3.2
Example: The height of a tree was 7 inches in
the year 2000. Each year the same tree grew
an additional 10 inches. Write an equation to
show the height h of the tree in y years. Let y
be the number of years after the year 2000.
The most literal equation might be 7 + 10y = h.
STRATEGIES
Dynamic Classroom Interactive
Scale--Big Ideas website
Human Equations
Algebra Tiles
Magic Square
Dynamic Classroom
Interactive Scale
This strategy gives students a visual
opportunity to see an algebraic
equation solved using a scale. This
demonstrates how equations must be
balanced.
Benefits: It allows the students to
enhance computer skills and provides a
high interest activity with graphics.
Human Equations
This is a kinesthetic activity that
provides the students with an
opportunity to move throughout the
classroom while modeling how to
solve one-step equations.
Benefits: Allows students to
cooperate in a group activity while
moving throughout the room .
How do I do this?
Students are given cards with numbers,
variables and symbols on them.
An equation is placed on the board.
X + 7 = 10 d – 8 = 9 a + 2 = 11
Students will model the equation with their
cards in the front of the class.
Students in the class are called on to solve
the problem by moving the cardholders as
they go through the steps of solving the
problem.
Algebra Tiles
They are used to solve algebraic
equations using colors and shapes.
Benefits: Students see positive and
negative integers in colors. It allows
them to see constants and variables
in different shapes.
Algebra Tile Example
Try x – 4 = 8.
Magic Squares
This is an enrichment option from
page 289 of the 6th grade textbook.
Benefits: This provides a
cooperative learning activity for
students to explore and expand their
comprehension of one-step
equations and encourages higherlevel critical thinking skills.
Magic Square…Your Turn!
Use equations to solve the magic square.
Hint: all lines horizontal, vertical and diagonal have
the same sum.

Example: It costs an initial fixed cost of $2
plus an additional $1.50 per mile to rent a
taxi. Write an equation that represents the
method for calculating the total cost of a
taxi ride? What is the total cost for a 5mile trip?

Example: Jan decided to save some money.
She already had $25. She received and
saved $5 on Friday each week for 8
weeks. Make a table and a graph of the
money she would have each week. If she
continues with this same savings plan,
how much money will she have after 2
years?

solve a system of linear equations?

Systems of Equations
MA.8.A.1.3
 Big Idea 1 - Analyze and represent linear functions, and
solve linear equations and systems of linear equations.
 Benchmark: Use tables, graphs, and models to represent,
analyze, and solve real-world problems related to systems
of linear equations.
MA.8.A.1.4
 Big Idea 1 - Analyze and represent linear functions, and
solve linear equations and systems of linear equations.
 Benchmark: Identify the solution to a system of linear
equations using graphs
Vocabulary 2-5
System of Linear Equations – two or more
linear equations placed together
Solution of the System of Linear Equations –
any ordered pair in a system that makes all of
the equations true.
No solution – when two lines are parallel there
are no points of intersection. Since the two
lines do not share a common point, there is no
solution for parallel lines.
Infinite solutions – a system of linear
equations has no limit to the pairs of solutions

Think – Pair - Share
Setup: Six note cards with the solving method
below: (2 cards per a method)
1. Solve Using Algebra.
2. Solve Using A Graph.
3. Solve Using A Table.
The teacher will give examples to the class, such
as: A middle school yearbook committee has 35
members. There are 7 more girls than boys. Use
the models to write a system of linear equations.
Then solve the system to find the number of boys
x and the number of girls y.
Procedure
Students will be in teams of 4. A stack of note cards
will be in each team. Each team will choose a note
card from the note card pile. Each student will allow
2-3 minutes to think and solve individually with the
method that is shown on their card. When time is up,
the students will share and check each others work
and come up with a consensus before they share with
the entire team. The teacher will then pick and review
answers and methods from 2 groups before moving on
to another example.

Food For Thought
Liping Ma (1999) used this exact problem with
teachers in the U.S. and in China.
Of 23 U.S. teachers:
– 6 could not create a story problem
– 16 created story problems with misconceptions
-Confusing dividing by 1/2 with dividing by 2
-Confusing dividing by 1/2 with multiplying by 1/2
– 1 provided a conceptually correct representation,
but it contained pedagogical problems
-Fractional number of children
90% of Chinese teachers created a correct
representation
