Teaching to the Next Generation SSS(2007)

Elementary Pre-School Inservice August 17, 2010

Next Generation Sunshine State Standards

- Eliminates:
- Mile wide, inch deep curriculum
- Constant repetition
- Emphasizes:
- Automatic Recall of basic facts
- Computational fluency
- Knowledge and skills with understanding

Coding Scheme for SSSK - 8

Participants will explore:

- Students’ progression from arithmetic to algebraic thinking
- Algebraic thinking “thread” in Grades 3 through 5.
- Introducing algebraic thinking through patterns

Algebra Thread

- MA.3.A.4.1Create, analyze, and represent patterns and relationships using words, variables, tables and graphs. (Moderate Complexity)
- MA.4.A.4.1Generate algebraic rules and use all four operations to describe patterns, including non-numeric growing or repeating patterns. (High Complexity)
- MA.5.A.4.1 Use the properties of equality to solve numerical and real world situations.(Moderate Complexity)

ArithmeticAlgebra

7 + 3 = _____ vs. _____ = 7 + 3

The language of arithmetic focuses on

ANSWERS

The language of algebra focuses on RELATIONSHIPS

Students begin describing mathematics inpictures, words, variables, equations, charts, and graphs.

Repeating Patterns

- Begins in Kindergarten
- Creating and Extending Patterns
- Naming the Pattern

Repeating Patterns

. . .

- What is the core of the pattern?
- To get at the predictive nature, you need to have terms specified: 1, 2, 3, 4, 5, 6, 7, ….

Repeating Patterns

- What is the next figure? How do you know?
- What is the 32nd figure? How do you know?
- What is the 58th figure? How do you know?
- Write how you know what numbers are hexagons.
- Write how you know what numbers are squares.
- Write how you know what numbers are triangles.

- What’s the core?
- What’s the 70th letter? How do you know?
- What’s the 75th letter? The 76th? The 77th?
- Write how you can determine the letter in position n, where n can be any whole number?

Year 3

In words, how do you describe the pattern?

Finding the Rule

Let nstand for age, finish the chart.

What Did We Do?

- Took an “interesting to kids” situation
- Made a chart to organize the data
- Described the data and made a generalization in words
- Described the data and generalization with a variable
- Tied in a visual aspect—justify the rule

Letter Patterns

Objectives

- Describe the growth pattern
- Record data on T-chart
- Describe the rule for growth in words
- Represent the rule with an expression
- Graph the function table

Making a Chart

- Make the H’s below on your graph paper.

- Make a chart of the term numbers and

number of tiles.

- Predict, before drawing, how many tiles

for the next H. Draw it to check.

How many tiles are needed to make the nth term?

- Can you explain why the nth term has that rule?
- What would this look like if you graphed it?

What Have We Done?

- Considered a sample of the types of patterns that students will encounter
- Described the patterns in words
- Used charts to see the patterns
- Generalized to a rule with a variable in order to predict

If you have an equation, you can +, -,

×, or ÷ both sides by the same number

(except dividing by zero), and keep

things “balanced.”

things “balanced.”

If two things are equal, one can be

substituted for the other.

Verbal & Algebraic Equations

- Three times a number , increased by 1 is 25.
- If 3 is added to twice a number, the result is 17
- When a number is increased by 8, the result is 13.
- Three times a number, increased by 7, gives the same result as four times the number increased by 5.

Building a Strong Algebra Foundation

With the algebra strand in 3-5,

we’re teaching kids HOW to think,

not WHAT to think.

(Marilyn Vos Savant)

How might you use your curricular materials to help your students develop algebraic thinking in your classroom?

What do you expect your students to find challenging about algebraic thinking?

How will you help them overcome these challenges?

What misconceptions might students hold about algebra and/or algebraic terms that you will need to address? How will you address these?
