House #1 House #2 House #3 House #4
This is the House That Jack Built
Jack has been building houses - they look like this:
1. Draw and label each of these houses.
2. For each house determine the number of squares.
3. For each house determine the number of triangles.
4. For each house determine the total number of pieces. 5. Organize your information in a table or in some other way.
7. Predict the number of triangles you would need to build House #10. Explain your reasoning.
8. Predict the number of squares you would need to build House #10. Explain your reasoning.
9. Predict the total number of pieces (squares and triangles) you would need to build House #14. Explain your reasoning.
Introducing Algebraic Notation
Moving from the specific to the general case.
Developing an understanding of variable and its uses.
Tying abstract ideas to concrete situations.
Fostering meaning to notation.
Developing the concept of equivalent expressions.
Encouraging efficiency and brevity in notation
Jack’s friend, Jill also builds houses. Her houses look like this:
House #1 House #2 House #3 House #4
1. Draw and label each of these houses.
2. For each house determine the number of squares.
3. For each house determine the number of triangles.
4. For each house determine the total number of pieces. 5. Organize your information in a table or in some other way.
7. Predict the number of triangles you would need to build House #10. Explain your reasoning.
8. Predict the number of squares you would need to build House #10. Explain your reasoning.
9. Predict the total number of pieces (squares and triangles) you would need to build House #14. Explain your reasoning.
11. Write a rule that gives the total number of triangles needed to build any house in this sequence.
13. Write a rule that gives the total number of pieces (triangles and squares) needed to build any house in this sequence.
A Critical Starting Point for Instruction
Not all tasks are created equal, and different tasks will provoke different levels and kinds of student thinking.
Stein, Smith, Henningsen, & Silver, 2000
The level and kind of thinking in which students engage determines what they will learn.
Hiebert, Carpenter, Fennema, Fuson, Wearne, Murray, Oliver, & Human, 1997
