6. Procedures/Methods-
|
|
A. Introduction-
1.Pose the following questions, "Every Saturday you play basketball
in the local community youth club. At the end of the season after

B. Development-
1. There will be teacher driven questions regarding the introduction
about what steps to take to solve the problem.
2.Have question posted on Promethean board and have students come
up and highlight what they think was most important in the passage.
|
| |
|
|
C. Practice-
1.Have students create number strips 1 - 9 and an equation on a
separate sheet of paper. For example a problem x + 5, where the number
strip is slid through a slit on the expression paper.
3. Students will go around the room and try to answer each others
expression. |
| |
|
|
D. Independent Practice-
1.Students will also do problems from a worksheet to practice the
new material.
2. Students will also work on answering a variation to the original
hamburger problem from above. |
| |
|
|
E. Accommodations (Differentiated Instruction)-
1. Students that have problems following directions will have help
from an aide in the room.
2. There is Promethean board instruction, book instruction, and the
whiteboard that may be used. |
