Teaching to the Next Generation SSS
(2007)
Mathematics Pre-School Inservice (6 – 8) 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 experience have clarified.
Comparison of Standards
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
Self Worth-If by chance you were to be auctioned off today what would your price tag be?
n Equations as an example standard linked through the grade levels
n Fair game review through models and visuals
n Use cooperative learning strategies to introduce or remediate equations
n Represent equations using models, vocabulary, pictures, and real world situations
n Lead students to mastery level not memorization
Teaching For Depth
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.

The Common Thread
What are the NCTM Process Standards?
– Problem Solving – Reasoning and Proof – Connections – Communication – Representation
12
NCTM Process Standards
" Problem Solving – Developing perseverance and critical thinking – Allow students think time to reach a solution
" Reasoning and Proof – Mathematical conjectures – Examples and counter examples
" Communication – Read, write, listen, think, and discuss – Increase the use of appropriate math
vocabulary
NCTM Process Standards
" Connections – Integers, expressions, and equations – Other content areas, science – Real-world contexts
" Representation – Useful tools for building understanding – Concrete - Representational - Abstract – Tables, describe in words, draw a
picture, write and solve equations
Focus on Equations!
6th Grade Equation Strategies
Solving one-step algebraic equations
NGSSS: Equations(6th)
" 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 higher-level 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.

RIGHT-BRAIN VS. LEFT-BRAIN ALGEBRA FOR BABY HOW DOES RIGHT-BRAIN VS. LEFT-BRAIN THINKING IMPACT YOUR BABY'S LEARNING FROM A CHILD DEVELOPMENTAL STAND POINT ? Curriculum–In order to be more “whole-brained” in their orientation, schools need to give equal weight to the arts, creativity, and the skills of imagination and synthesis. "Baby Algebra" is Right-Brain vs. Left-Brain application. If you have made it to this Google Blog, You are ready for Change. Welcome to Algebra Change for Baby and you
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.
Where do they go from here? " Algebra MA.912.A.3.1: 3(2x+5) = 10x-3+2x
" Geometry MA.912.G.5.4: Are these equations parallel, perpendicular, or intersecting.
y = 3 (x - 3) + 9 y = 2.1 (x + 2) - 4
" Algebra II MA.912.A.6.5 : 3 log x = 4

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
