Development (20 - 25 minutes)

1. Activity 1: Operation Bingo (10 - 12 minutes)

   • The teacher prepares the Operation Bingo cards prior to the class. Each card features a range of simple whole number operations, such as 5 + 3, 10 - 7, 2 * 4, 16 ÷ 4, etc. The numbers used in the operations should not exceed 20.

   • The teacher explains that students will be playing a modified version of Bingo. Instead of calling out numbers, the teacher will call out operations. The students will have to solve the operation and mark the corresponding answer on their Bingo card, if it's available.

   • The teacher distributes the Bingo cards and a set of markers to each student.

   • The teacher starts calling out the operations, ensuring to read them aloud to allow visual and auditory learning. For instance: "The operation is 7 + 8. What's the answer?"

   • If a student has the correct answer on their Bingo card, they mark it. The first student to mark a full line (horizontally, vertically, or diagonally) or a full house (all the answers on the card) is the winner.

   • The teacher repeats the game several times with different operations to allow all students to participate and get a chance to win. This game helps students to improve their mental math skills and become more comfortable with the basic operations of whole numbers.

2. Activity 2: Real-World Problem Scenarios (10 - 12 minutes)

   • The teacher prepares a set of cards each containing a real-world problem involving whole numbers. Each card should have a question, for example: "If a pizza has 8 slices and you eat 5, how many are left?" The question should be followed by a space for the answer.

   • The teacher distributes the problem cards to groups of students.

   • The students, in their groups, read the problem, and discuss the operations required to solve it. They then solve the problem on their card and write the answer in the space provided.

   • The teacher walks around the classroom, observing, offering guidance, and ensuring that all students understand the problems and are correctly applying the operations.

   • After all the groups have solved their problems, the teacher collects the cards and shuffles them.

   • The teacher then redistributes the cards, making sure that no group receives its original problem. This way, students are encouraged to explain the solution process to each other, promoting peer learning and collaboration.

   • The process continues until all the problems have been solved and checked, and all the students have had an opportunity to work on different problems. This activity helps students to understand how to apply the basic operations of whole numbers in real-life situations, thereby reinforcing the relevance of these operations.

3. Activity 3: Operation Relay Race (Optional, 5 - 7 minutes)

   • This activity is a fun and engaging competitive game that consolidates learning and encourages students to think quickly. The class is divided into two or more teams.

   • At the front of the classroom, the teacher sets up stations, each containing a different problem card and a box with the necessary manipulatives (such as counters or small toys) to solve the problem.

   • One student from each team starts at a station. When the teacher says "Go!", the first students in line rush to their stations, solve their problem, and place the corresponding number of manipulatives into their team's basket. They then tag the next person in line, who does the same, until all the problems are solved.

   • The team that correctly solves all the problems first and has the most manipulatives in their basket is the winner.

   • This activity reinforces the learning of all students as they are required to solve different problems and explain the solution process to their teammates. It also encourages a sense of healthy competition and teamwork.
