The document describes a tower made of bricks where each row contains a number of bricks. It poses questions about determining the number of bricks in different rows, describing a rule to calculate the bricks in any given row, finding the total bricks to build the tower shown or ones with additional rows, and deriving a general rule to calculate the bricks in a tower based on the number of rows.

1. Day 1
5-Minutes

2. (Driscoll, 1999)
• Each row of the tower is made up of some number of
bricks.
• How many bricks are used in the 7th row of the tower
pictured above?
• If the tower kept growing, how many bricks would be
needed in the 8th row, and the 9th row?

3. Day 2
5-minutes

4. (Driscoll, 1999)
• Each row of the tower is made up of some
number of bricks.
• Describe a rule that will tell you how many
bricks are in the 25th row, or the 50th row, or
in any row.

5. Day 3
5-Minutes

6. (Driscoll, 1999)
• Each row of the tower is made up of some
number of bricks.
• How many bricks are needed to build the tower
pictured above?
• How many bricks are needed to build a tower
with ne more row than the one pictured above?

7. Day 4
5-Minutes

8. (Driscoll, 1999)
• Each row of the tower is made up of some
number of bricks.
• How many bricks are in a tower with 20
rows?

9. Day 5
5-Minutes

10. (Driscoll, 1999)
• Each row of the tower is made up of some
number of bricks.
• Describe a rule that will tell you how many
bricks are in a tower if you know how many
rows are in the tower.
