Lesson Plan : Adding double digit numbers
Teacher Name: | Jennifer Stidham |
Grade: | Grade 2 |
Subject: | Math |
Topic: | Addition of double digit numbers |
Content: | ones place tens place ones tens long regroup add |
Goals: | Add two double digit numbers together, such as 11+13. |
Objectives: | The student will be able to use cubes placed on a places chart to show the answer to a given addition problem by the end of the lesson. |
Materials: | Places chart Linking cubes |
Introduction: | Tell the children a story about how they can use addition in their everyday lives. |
Development: | Begin the lesson by giving each student a paper with the places chart on it. Then give each student a bag of linking cubes. T: Today we are going to talk about addition. What do you know about addition? ER: It's when you take one number and add it to another number to get a bigger number. It's easier than take away. (Accept all reasonable answers, Write all answers on the board) T: All of these are great answers. Directions: Teacher writes an addition problem on the board. Then asks the students to use their linking cubes to solve the problem on their papers. Teacher walks around observing, answering questions and assisting. Teacher gives lots of praise the whole time. |
Practice: | Have a student give you an addition problem to solve. 12+18 Write the problem on the board. Explain to the students that we are going to practice together. Ask students to first show the number 12 on their charts. After that they then need to show the number 18. Ask them if any regrouping needs to be done. (They should say yes) Have them regroup their cubes. Ask them to shout out the answer to the problem. (30) |
Accommodations: | For a child with special needs I might have them sit on a rug in the floor to use their cubes if they have trouble using them at their desk. Instead of using linking cubes to solve the problem I could use candy or stickers which the child could have after solving the problems. If a child truly was not grasping the concept I would find some one on one time to work with that child to help them gain a better understanding. I would let the child solve the problem on the board allowing them to create whatever design they wanted to represent the numbers. (For example, they might draw smiley faces to represent the numbers, then they could circle the smiley faces to show regrouping.) |
Checking For Understanding: | |
Closure: | Explain to the students why we use addition. Tell them how they can use it in their everyday lives to make things easier. |
