-
The teacher will present flashcards that will give them some clues about the lesson.
-
The task of each student is to guess and tell what those are.
-
The students who will be able to guess those clues correctly will be given prizes.
By doing this activity, the students will have an idea about the lesson for that day.
Lesson Procedure
-
Before starting the lesson, the teacher will ask some questions that the students need to answer.
Guide Questions:
-
Do you have any idea on how we multiply numbers?
-
Can we apply multiplication in real life situations? How?
By answering the questions, the teacher will have an idea about the students’ background knowledge. Then, she will connect those ideas to introduce the topic or lesson.
2. In the discussion, the students will listen about the steps in multiplying numbers.
3. Then, after discussing it shortly, the students will play an activity that will let them practice multiplying numbers.
Activity Title: Solve it!
Mechanics:
-
The teacher will give 5 mathematical equations written in the board.
-
The teacher will call 5 volunteer students who will answer those equations.
-
On the other hand, other students will also practice solving the equations in their notebooks or papers.
4. After playing the activity, the teacher will give some real-life word problems related to multiplication and show how it can be solved.
5. Then, she will play another activity to let the students practice solving real-life word problems related to multiplication.
Activity Title: Minute to Win it!
Mechanics:
-
The class should be divided into 4 groups. Each group should have 5 to 6 members only.
-
The task of each group is to solve the 5 real-life word problems related to multiplication that teacher will give before the activity.
-
The challenge in this game is they are only given 1 minute to answer each question.
-
The group who will have the correct answer will be given 2 points.
-
The group who will have the highest number of points will be the winner of the game and will be given prizes.
6. For the “Assessment”, the teacher will use the performance task to test if they really learned all the lesson.
7. To end the lesson, the teacher will let the students share what they’ve learned by writing it in a flashcard. The students can also share their opinions or insights about the lesson.
-
By doing this activity, the teacher will know the students’ learnings, opinions and insights about the lesson.
