Lesson 1: Adding three numbers
Performance Objective: Students will be able to use previously learned strategies to regroup numbers to use with known addition facts so they can solve the multi digit addition equations when given a worksheet to complete, with 60% accuracy.
Resources or Materials Needed: Handouts, workbook, I-ready online lessons, whiteboard, smart board, teacher slides (Power Point), document camera, manipulatives in various forms (10 frame, connecting blocks, tiles and cubes), and anchor charts found in classroom with grouping strategies demonstrated.
Time: 80 minutes total
Step 1: Pre-Instructional Activities: (15 minutes)
Students will be given an example situation where three digit addition would be needed.
Read story problem from board:
Bo, Luke and Nick are adding up how many cars they have to play with in the toy corner. Bo has 2 cars, Luke has 3 cars and Nick has 5 cars. How many cars do they have all together?
Ask: Would I count them one by one?
Ask: Is there a faster way to add them up?
Ask: What numbers can I put together that I know well?
Have the actual cars available to show an manipulate. Allow students take turns demonstrating their thinking by regrouping the cars and explaining to the class why they chose to do that. Turn and talk can be used as a way to share student noticing.
Step 2: Content Presentation: (20 minutes)
Teacher will present different problems on the smart board. The first problem will be modeled to demonstrate math thinking and strategy use.
Read story problem from board:
Kia has 4 red blocks, 2 blue blocks, and 1 green blocks. How many blocks does she have in all?
Ask: How many blocks does Kia have? How do you know?
Ask: What ways can we use to add these numbers together to find the total? (doubles, grouping, etc.)
Ask: How can you use different groupings and still get the same total?
Teacher will work through all the slides provided for this lesson.
Step 3: Learner Participation: (15 minutes)
Students will then get their pockets and pen and begin doing practice problems that are guided by the teacher from the smartboard and students will participate in elbow partner turn and talks after each problem on each slide.
Once the lesson is completed, students will show a ‘fist to 5’ to indicate their level of understanding of the lesson.
Step 4: Assessment: (20 minutes)
Completion of workbook pages 305, 306, 307, and 308 from their workbooks. Once the worksheets are completed, students are to use the online extension lessons on their computers from the I-Ready website that have assigned lesson on the same content.
Step 5: Follow-Through Activities: (10 minutes)
The next morning’s entry ticket to be used as a re-check and follow-through activity.
Lesson Plan Summary:
This lesson is focused on identifying relevance and practical application in the use of a multi digit equation. Additionally, students will be able to use manipulatives to demonstrate a strategy to regroup when solving the equation. The use of manipulatives and student discussion when exploring the new concept allows for deeper understanding. This lesson is designed with constructivism as the focus.
Lesson 2: Regrouping to add three numbers
Performance Objective: Students will be able to use previously learned strategies to regroup numbers to use with known addition facts so they can solve the multi digit addition equations when given worksheets to complete, with 80% accuracy.
Resources or Materials Needed:
Handouts, workbook, I-ready online lessons, whiteboard, smart board, teacher slides (Power Point), document camera, manipulatives in various forms (10 frame, connecting blocks, tiles and cubes), and posters in classroom with grouping strategies listed.
Time: 80 minutes total
Step 1: Pre-Instructional Activities: (15 minutes)
Students will begin this lesson on the rug with the teacher launching the lesson on the smartboard. Asks can be answered by several students and in turn and talk partner talks.
Read story problem from board: Pat collects 6 cans of food. Max collects 2 cans. May collects 4 cans. How many cans do they collect in all?
Ask: How is this problem like the one you solved yesterday?
Ask: How is it different?
Ask: Which addend did you group together first?
Ask: Did you try it any other way?
Ask: Did your partner solve this problem the say way as you?
Step 2: Content Presentation: (20 minutes)
Teacher will model the story problems on the smart board and regrouping of digits. Write: Asha makes 6 puppets. Jay makes 4 puppets. Tomas makes 3 puppets. How many puppets do they make in all?
Ask: Did you group two numbers to make 10??
Ask: How does making a ten make it easier to find the total of three numbers?
Ask: Do you think there will always be two numbers that are partners for 10 when adding 2 numbers?
Work through all slides in lesson set while modeling noticing and wonderings about regrouping. After the lesson, have students show a ‘fist to 5’ to indicate their level of understanding of the lesson.
Step 3: Learner Participation: (15 minutes)
Students will then get their pockets and pen and begin doing practice problems that are guided by the teacher from the smartboard and students will participate in elbow partner turn and talks for each slide.
Once the lesson is completed, students will show a ‘fist to 5’ to indicate their level of understanding of the lesson.
Step 4: Assessment: (20 minutes)
Students will complete worksheet pages 313 and 314 from their workbooks. Once the worksheets are completed, students are to use the online extension lessons on their computers from the I-Ready website that have assigned lesson on the same content.
Step 5: Follow-Through Activities: (10 minutes)
The next morning’s entry ticket to be used as a re-check and follow-through activity.
Lesson Plan Summary:
This lesson is focused on identifying relevance and practical application in the use of a multi digit equation. Additionally, students will be able to use manipulatives along with written work to demonstrate a strategy of regrouping when solving the equation. The use of student discussion (noticing and wonderings) when exploring regrouping allows for deeper understanding of the strategy. This lesson is designed with constructivism as the focus.
Lesson 3: Solving when adding three numbers.
Performance Objective: Students will be able to use previously learned strategies to regroup numbers to use with known addition facts so they can solve the multi digit addition equations when given a worksheet to complete, with 80% or more accuracy.
Resources or Materials Needed:
Handouts, workbook, I-ready online lessons, whiteboard, smart board, teacher slides (Power Point), document camera, manipulatives in various forms (10 frame, connecting blocks, tiles and cubes), and posters in classroom with grouping strategies listed.

Begin session by asking what the word ‘order’ means in math. Guide students to realize that things can be arranged in different orders (tallest to shortest, dark hair to light hair, short hair to long hair, etc).
Read story problem from board: Adam plants 6 flowers. Kate plants 5 flowers. Yuri plants 6 flowers. How many flowers do they plant in all?
Ask: How many flowers does Adam Have? How many flowers does Kate have? How many flowers does Yuri have?
Ask: What is the problem asking us to do?
Ask: How did you get started?
Ask: Did your partner solve the problem in a different way than you?

Assessment
The summative assessment will be given on the fourth day. Students we be given a ‘pep talk’ about the following things to remember when completing their assessment:
- Take your time, we have plenty of it
- When you get stuck, take a breath and use positive talk
- Show you math thinking on the paper
- Keep your eyes on your own paper
- Raise your hand and wait patiently until I come talk to you if you have a question
- No talking during the test
- Stay in your seat for the whole test
- Try your best, I believe in you!
