6. Procedures/Methods-
|
|
A. Introduction-
1. Students complete the 5 minute check (review of Lesson 2-4) in
their math notebooks.
2. Students complete the Problem of the Day in their notebooks.
*This work is completed independently and then checked as a group.
3. Have each student get a turn to state the doubles facts from 0-10.
Give 1 bulldog buck upon completion.

B. Development-
1.Have a student roll a number cube and each student write the number
down on his whiteboard.
2. The teacher asks the "main" student (person who rolled the dice)
what that is that number
*Complete 4x
3. Return to the first person's white board and ask the student to
identify what is one more than 1 of the addends (i.e. 7+7, what is
1 more than 7 - 8+7). Have the student find the sum, by explaining
that you are only adding 1 more number so if 7+7=14 then 8+7=15).
Use visual supports if the students have difficulty with comprehension.
*Repeat with each whiteboard
4. Model for the students the top portion to text page 67. The teacher
will use the number cubes and then ask students for assistance as
she models. |

|
|
C. Practice-
1. Have the students use cubes to solve problem 1 on text page 67.
2. Complete questions 2-14 as a group, allowing the students to rotate
around the table answering each question.
*If students are having difficulty with the concept, revert back to
use of number cubes.
|
| |
|
|
D. Independent Practice-
1. Have students complete problems 15-16 on page 68 of the text
independently.
*Monitor for skill comprehension |
| |
|
|
E. Accommodations (Differentiated Instruction)-
1. Use number cubes to help solve problems and explain the concept
of doubles plus one.
2. Use visual supports (i.e. lines or circles) or counting on fingers
for those students who struggle with the larger addends.
3. Use of a paraeducator to assist one student and provide additional
support and reinforcement, as needed.
4. Modify language and review any concepts if students are struggling. |

|
|
F. Checking for understanding-
| Check the independent work (questions 15-26) as the students work.
Check the homework the following day and the home-school books for
any feedback on homework issues. |
| |
|
|
G. Closure-
| Exit ticket: Ask each student to write down a doubles problem and
a near doubles problem, solve it, and hand it to the teacher. If the
answer is correct the student can earn their star on the point card. |
