Introduction (10-15 minutes)

1. Recalling concepts: The teacher starts the class with a brief review of the addition and multiplication concepts learned earlier. They can offer simple problem-solving situations involving these operations, encouraging students to solve them individually or in groups. This helps reinforce the foundation necessary for understanding the new concepts.

2. Contextualized problem situations: The teacher presents two problem situations involving multiplication by 2, 3, 4, and 5. The first situation can be related to a birthday party where students must calculate how many balloons are needed if each child can take three balloons home. The second situation can involve distributing candy in a classroom, where students must find out how many pieces of candy each will receive if the teacher distributes four pieces to each. The teacher can use real objects or images to represent these situations, making them more concrete and understandable for students.

3. Putting multiplication in context: The teacher explains that multiplication is an essential mathematical operation used in everyday situations. They can give simple examples, such as calculating the number of fruits needed to make juice if each glass requires five fruits or calculating the total amount of money needed to buy four toys if each toy costs $3.00. This helps students see the relevance of this content and motivates them to learn.

4. Introducing the topic with curiosities: To spark students' interest, the teacher can share some fun facts about multiplication. For example, they can mention that multiplication is a quick way to perform multiple equal additions or that the multiplication table is a "recipe" that helps us find the result of a multiplication without counting one by one. The teacher can also say that multiplication is used in many professions, such as cashiers, cooks, and builders, to make their work easier.
