General Goal
: Students will be able to test whether 1, 2, or 3 digit numbers are divisible by 3, 6, and 9. Students will be able to recite what divisibility is.

Specific Objective
: Students will be able to use divisibility tests for 3, 6, and 9.

Materials needed
: Math textbook, Post-it notes ©, and calculator for student X.

Estimated time required
: One block schedule period.

Planned classroom management strategies
: Teacher will use whole group instruction and give individual attention to students who need it.

Procedural:

A. Motivating activity- Teacher will place a 2-digit number on the board (75). The teacher will ask the students to decide whether the number is divisible by 3. The teacher will place an X axis and Y-axis on the board to represent a graph. Yes and no will be placed underneath the X-axis. The teacher will give each student a Post-it note ©. Students will stick the Post-it notes © on X-axis on the board over the yes or the no to form a bar graph with the Post-it notes ©. Teacher will discuss the bar graph briefly and then introduce the math rules for 3, 6, and 9 to help students determine if an nth digit number is divisible by 3, 6, and 9.

1. Teaching
1. Demonstration/Modeling and Guided Practice: Teacher will read the rules for determining if a number is divisible by 3. The teacher will then model the rule on the board using the sample given in the text. Students will help the teacher determine whether the number is divisible by 3. Next teacher will read the rules for determining if a number is divisible by 6. The teacher will again model the rule on the board. Students will help her determine whether the number is divisible by 6. Teacher will then go back to the warm-up, and use the rules to determine whether the number is divisible by 3 or 6. The students will then check their answers.
2. Independent Practice: Teacher will then ask the students to do the practice problems. Teacher will float around the room to assist students who will need help.
2. Accomodation/Adaption- For student X, who has an I.E.P., teacher will give him a calculator. (The calculator will help student X to focus on the objective of determining divisibility rather than occupied with finding the sum.) Student will use the calculator to conclude the sum and then use the rules to determine if the number is divisible by 3, 6, or 9.
3. Evaluation/Testing/Procedure for Collecting Formative and Summative Evaluation-
1. Formative: Teacher will observe student progress during independent practice.
2. Summative: Teacher will give a quick quiz at the end of the period. (For quick quiz students will determine whether 438, and 537 are divisible by 3, 6, or 9). The teacher will place two problems on the board for the students to work out. Teacher will ask students to complete the problems and then reflect on one of the problems by explaining how the rules helped them to decide whether a number is divisible by 3, 6, or 9.

Reflection/Self-Evaluation: Based on the results of the quick quiz, teacher will decide if the lesson was effective and whether or not to proceed to the next lesson.
