 * Name: Rebecca Jones_ Grade Level:__3rd__**
 * Estimated number of days lesson will cover: __1___**
 * Lesson Subject/Title:
 * Performance Standards:

M3N2. Students will further develop their skills of addition and subtraction and apply them in problem solving c. Solve problems requiring addition and subtraction ||
 * Lesson Objectives (What students will know and/or do) :

What are the different ways to add and subtract wholes numbers?

Enduring Understanding: Learning computation skills that will assist you in everyday experiences. ||
 * Essential Questions:

What are the different ways to add and subtract wholes numbers? || Place value Regrouping Renaming ||
 * Key Vocabulary:

-Start by reviewing place value. I will stand in designated areas in the front of the room and ask the students which place value I am located in -review three digit addition on board with disks ||   ||   || Verbal- do they remember the place value, can they tell me which value ||
 * Time || Procedures || Differentiation || Materials/Resources || Assessment ||
 * 2 min || Introduction/hook/activation of prior knowledge
 * 20min

5-10 min

15 min || **Instructional activities** -draw ones/tens/hundreds/thousands place value and model 4 digit addition with only the place value disks (4567+4535) –ask the students how to add and write it vertically -model another four digit addition with the disks and the standard addition form. Show where the disks correspond to the steps in the standard form (1266+2355 and 3589+2443) -model in standard form only (4396+2895)
 * Demonstrate/Model (if appropriate)**

-instruct students to take out paper and work out problems with me as I do them on the board (3614+5327 and 2378+2534) have students tell me each step as they do the steps on their paper
 * Guided Practice (if appropriate)**

-p. 48-49 in math w.b. finish for homework if not completed. (rotate and check while students are working independently) || -model addition with the placement disks, using the standard form, and also using these two techniques together.
 * Independent Practice (if appropriate)**

-during the rotate and check if students are still struggling advise them to take out a piece of notebook paper, turn it sideways and write the problems, adding them on there -pull a small group and allow them to use number disk if still not grasping || -placement disks -math workbooks || -verbal

-visual during the rotate and check

- mastery grade from h.w. || -If we have 12 ones in the ones column what do we do? REGROUP and MAKE A TEN! ||  ||   ||   ||
 * || **Review and Closure**
 * -**Recap adding with four digits, emphasize digits 1-9 can be in each place value colulmn
