Lesson Topic or Theme: Addition

Lesson Objective

Students will be able to add numbers using concrete models, drawings, or place value

Instructional Technique

• Whole group lesson
• Independent work

Instructional Materials

• Attached to end of lesson – Addition Strategies - 
  

Theoretical Perspective

• This information is important for second graders to learn because it provides the skills they need to do addition problems wherever they go. This is important to learn because students can use it throughout their lives and allows them to quickly do math. Students can encounter many situations where they could have to do math and it’s important for students to have the skills to complete these problems.

•  The students will first start on the rug in a whole group lesson
• Here the teacher will conduct a discussion about what strategies students could use to solve subtraction problems
• The teacher will guide the students in the direction of using hundreds charts, and place value pictures
• The teacher will give students two examples and show them how both these strategies would look like when they use it
• After the class finishes their review the teacher then will hand out their packets to be completed for the rest of the class
• The students will be asked to go back to their seats and silently work on their packets
• The teacher will be available to assist students that need help, but will encourage them to try their hardest first and then ask for help when they are really stuck

A. Introductory Activity

•   Students will start out by doing a quick warm-up activity to test what they know about adding
• Each table will be given to problems to work on as a group, once the table solves both problems the teacher will check them and ask the students to go to the rug if they are correct
• Once all students answer the problems correctly the class will gather around the rug for a whole group lesson

B. Step-by-step

• Students will gather around the rug facing the whiteboard
• The teacher will cover all the strategies that students can use to solve addition problems, counting up, hundreds chart, place value pictures, and other strategies that could be helpful for students
• The teacher will show students an example or two depending on the students understanding of the first problem – because the students will be working with higher numbers as they go the teacher will give examples with numbers in the hundreds, tens and ones place – 130+63, 233+50
• The teacher will show the students how to solve the problems with multiple strategies before the students go back to their seats for independent work
• Once students are in there seats they will complete the addition strategies sheet, here they can complete the problems using any strategy they would like but they must show or say how they solved it
• The teacher will walking around checking students work as they go and helping when they need it

C. Closure

• 10 minutes before the lesson ends and transitions into the next topic, the teacher will bring the students back to a whole group discussion
• The teacher will have the students share how they got to their answers for at least 2 of the problems and have at least 3 to 4 different strategies the students used to solve them
• The teacher then will explain how addition can be useful in our everyday life and the students will be using their addition skills to help Sam through her road trip

D. Adaptations for different learners

• Students will be able to use any strategies they would like that is best for them to solve the problem
• Students will have access to any manipulative, or tools that could be helpful, like the hundreds chart, or place value blocks
• The teacher will also show the students multiple ways to solve addition problems as well as show them and leave them on the board for students to reference back to if they need

Evaluation

A. How/ when will you determine if you have met your objectives?

• Students will be able to add numbers using concrete models, drawings, or place value

o   The teacher will determine when students have met these objectives by assessing the work they have completed in the worksheet, as well as the whole group discussion at the end of the lesson. The worksheet can help the teacher determine which way best worked for the student and if they used it correctly to arrive at the answer. The whole group discussion will also be helpful for the teacher to assess the students thinking process. By having students explain what they did gives the teacher a basic understanding of what the student is thinking while they are doing addition problems.

B. Concerns or questions you have about teaching this lesson?

• One concern that I have about this lesson is students understanding the 100s place value and how to add numbers to three place values
