| Graph, develop ordered pairs and relationships. | Encourage students to predict how changing a set of
coordinates will affect the graph. Ask students to explain their thinking.
|
Plot a given set of points to create a picture. Students then
generate a new set of points by applying some rule to the coordinates of the original
picture. Ex: multiply each y coordinate by 2.
|
Students are presented with physical patterns and asked to express them algebraically. | Generate their own graph pictures, determine how they wish to enlarge, reduce, distort these pictures, then construct a rule and write clear directions for another student to complete the activity. | Algebra Thinking: First Experiences - Bob Wolcutt.

| Generate rules by simple concrete
models.
|
Ask questions such as: " How many cubes would I need to construct the 3rd figure, 4th? 5th? 10th?100th? If I know the number of figures I want to make, how can I figure our how many cubes I will need? | MODELING ACTIVITY: with teacher
direction, use cubes to build sets of items that follow a physical pattern. They make
tables showing the number of cubes in each iteration of the figure, then look for
numerical pattern that can be expressed using a variable.
|
Student should be able to accurately predict how a change in coordinates will affect the subsequent picture. | - Given a relationship expressed algebraically, build sets of
models that fit the relationship. Students compare their sets for similarities and
differences. - Use two types of pattern blocks in each model thus requiring the use of two variables in the algebraic expression.

| Develop order of operation patterns and results on a calculator. | Supply students with a variety of calculators, some of which follow the order of operations automatically and some of which do not. |
|
Students write their own problems that will produce incorrect
answers if the order of operations is not used.
|
Rewrite given problems to show the order in which items must
be entered into the calculator to show how life was in the days when calculators could not
follow the order of operations.

| Identify, develop patterns in tables,
graphs, rules, etc. to solve problems.
|
Show work for two or more patterns. Ask students to compare the rules and tables of each. Use those to explain similarities/differences in corresponding graphs. | For the MODELING ACTIVITY described above, graph their results and use their equations and graphs to predict new values. Students compare graphs of different patterns and begin to make predictions of how specific equations will look when graphed. Ex. x=y is a diagonal line intersect the origin. Another similar line is x=-y | Given two patterns, students identify the pattern that will
generally require more cubes to construct and explain how the subsequent graphs will be
similar or different.
|
Given a table, write a rule to show the pattern in the table, supply new numbers for the table and graph the points. | Algebra Thinking: First Experiences - Bob Wolcutt. | |

| Use variable to symbolize relationships
between the four fundamental operations.
|
|
In the MODELING ACTIVITY described on p. 178, students will find a variety of ways of expressing the same relationship. Ex: 2x +3 = x+x+ 3 . | Generate multiple ways to correctly express a given
relationship algebraically.
|
Use manipulatives and drawings to write a journal entry
showing why two expressions are equivalent.

| Solve, develop simple linear equations using manipulatives and models. | Encourage students to verify that their equation, table and graph are all consistent with each other. Help them use their physical models in making necessary changes. | In the MODELING ACTIVITY described on
p. 178, students will write an equation showing the relationship between the iteration and
the number of cubes needed in the model. They substitute numbers from their tables to
check their equation.
|
- Given a physical pattern, students construct a table and
express the relationship of paired items algebraically. - Given an algebraic equation, students construct a set of models to demonstrate the corresponding pattern.
|
Given a table, write an equation that describe the pattern in
the table.

| Identify mathematical relationships
occurring in other curricular areas (art, literature, etc.).
|
- Demonstrate the application/ integration of mathematical
concepts through the reading of Gulliver's Travels by Swift. - Create a bulletin board area designated Math Applications.
|
Bring in examples of math concepts in other curricular areas to share with class and post on bulletin board. | Publish an original piece of fiction that incorporates math
concepts and/or patterns. Share with an appropriate audience.
