Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

Teacher: Good afternoon class. Today we are going to learn about adding and subtracting fractions with like denominators.

Teacher: Let's start with a quick review. Using fraction bars, who can tell me how to identify the denominator and numerator of a specific fraction? (Pause for a couple of seconds for students to answer).

Student 1: The top number is the numerator and the bottom number is the denominator.

Teacher: Great job! Now let's find another fraction with the same denominator. (Wait for students to respond).

Teacher: Now we are going to learn how to add fractions with like denominators. (Write an example on the whiteboard).

Teacher: We have 1/2 plus 1/2. If we add the numerators, we get 2. And the denominator stays the same. So the answer is 2/2 or 1. Does anyone have any questions?

Teacher: Now we are going to practice adding fractions with like denominators using fraction strips or circles. (Distribute the materials). Please add 3/4 and 2/4. (Ask for a volunteer to solve the problem on the board).

Teacher: Good job! Can someone explain how they solved the problem?

Student 2: We added the numerators and kept the same denominator.

Teacher: Excellent explanation. Now everyone tries the problem on their own. (Wait for students to finish).

Teacher: Our next activity is to complete a practice problems worksheet on adding and subtracting fractions with like denominators in simplest form. You have 7 minutes to finish these problems. (Distribute the worksheet).

Teacher: Let's review the answers to the homework assignment from the previous lesson. (Display the answers on the board).

Teacher: Excellent job, everyone!

Teacher: Let's recap what we have learned today. What is the key takeaway from today's lesson? (Wait for students to respond).

Student 3: We learned how to add and subtract fractions with like denominators.

Teacher: Yes, that's right! Thank you and have a great day!
