In the first week of November, Grade four students at SHSID Pudong Campus ushered in a colorful mathematics week. From November 7th to November 11th, students experienced math activities with different themes every day.

During Wednesday's math class, students became explorers, racing against the clock with a Sudoku treasure hunt. They needed to find the task cards hidden by the teachers in every corner of the classroom, solve the above equations, and get clues. After that, students had to fill in the clues into the Sudoku table and use the Sudoku-solving strategy to complete the challenge.

Before enjoying the exciting math game, children needed to patiently learn the math knowledge involved in each activity and the game rules, and cooperate and run-in with group members during the activity to improve their teamwork ability. Through these wonderful activities, all grade four students have improved their perception ability and interest in mathematics learning has been greatly stimulated!
