One possible group activity for grade 1 learners in mathematics with the topic of adding numbers using peso money is the “Money Race” game.

Materials needed: - Peso coins (various denominations) - A dice - A game board (drawn on a large piece of paper or cardboard)

Instructions: 1. Divide the students into small groups of 3-4 learners. 2. Give each group a set of peso coins. 3. Draw a game board on a large piece of paper or cardboard. The game board should have a path with squares numbered from 1 to 20. 4. Each group selects a player to start the game. 5. The first player rolls the dice and moves their game piece along the path according to the number rolled. 6. When a player lands on a square, they must add the value of the coin they are holding to the total amount. 7. The player then takes another turn by rolling the dice again. 8. The game continues until one player reaches or exceeds a predetermined total amount (e.g., 100 pesos). 9. The player who reaches or exceeds the total amount first wins the game.

During the game, encourage the students to count the value of the coins they have and add them correctly to the total amount. This activity will help them practice adding numbers using peso money while also developing their counting and addition skills.
