In the vibrant May ，we embraced our long-awaited "5th primary Maths Week"! Over the past week, students from each grade transformed into "Maths Whizzes" through PBL exploration. 

Grade 1 built a "Rainbow Wonderland" using geometric shapes, Grade 2 solved treasure hunt puzzles using coordinate skills, Grade 3 transformed into campus architects, using scale models and data-driven designs to build the school of tomorrow!  Grade 4 became “Nutrition Ninjas”—they analyzed food waste with bar graphs. Grade 5 became "Green Designers"—they used surface area formulas to create eco-smart packaging boxes! Every project shows how maths connects to our world!

Grade 1 Maths PBL

In this maths PBL activity, grade 1 turned discarded materials like cardboard boxes and bottle caps into creative treasures—crafting whimsical "reference buddies" in all shapes and sizes. Standing about 10 cm tall, these charming figurines weren’t just measurement tools; they sparked ideas for miniature amusement park designs. From popsicle-stick seesaws to cardboard slides, every creation showcased the perfect blend of maths and aesthetics.

Measurement goes beyond mere numbers. Through this cross-curricular project, students deepened their understanding of centimeters, honed spatial reasoning skills, and developed eco-awareness—embodying the competency-based learning approach promoted by modern educational standards.

In this journey where knowledge intersects with creativity, young learners are using maths to explore the world and illuminating childhood with innovation.

Grade 2 Maths PBL

During Maths Week, grade 2 embarked on a fun-filled "Direction Exploration" project. Students learned practical orientation skills through hands-on activities like creating pop-up books and interactive games, gaining valuable real-world knowledge.

With the theme "Traveling with Maths," each student designed their own creative pop-up book. They crafted adventurous stories about directions, used recycled materials to build their books, and even shared practical tips like how to determine directions using the sun's position and road signs.

By the end of the project, the students had mastered using "north, south, east, and west" to navigate their surroundings. A perfect blend of creativity and real-world maths skills!

Meanwhile, grade 2 also collaborated to create a 3D campus map using school buildings as models. Working in groups, students designed treasure hunt routes from the school gate (Point A) to the library (Point B): some teams used arrow symbols to plot the shortest path, while others marked directional instructions like "Go east past the basketball court, then head straight north" with colorful markers. Through this hands-on activity, they literally brought flat maps to life!

Through this engaging project, our grade 2 not only mastered fundamental directional concepts, but also discovered the joy of teamwork and collaborative problem-solving.

Grade 3 Maths PBL

During Maths Week, grade 3 brought their familiar campus to life through creativity and hands-on craftsmanship, working on the theme of "Campus Architectural Model Building."

The class split into seven groups, each tackling a different landmark—Building A, Building B, the residence hall, the soccer Field, the basketball and tennis courts, the flowerbed and playground, and the sports centre. Collaboratively, they built scale models at a 1:100 ratio, putting their maths lessons on "scale measurements" to practical use.

Creative Details:

The sports centre team’s meticulous attention to detail earned unanimous praise from everyone!

Clever Designs:

The cafeteria group sculpted miniature dining tables out of clay and even painted the day’s menu on the serving window! To recreate the soccer field realistically, the students used actual turf for the grass!

When all the models were put together, everyone was astonished—the flowerbeds beside the classrooms burst with colorful crepe-paper blooms, the cafeteria’s chimney puffed tiny curls of clay 'smoke,' and the school gate pathway was lined with fine gravel, making it feel like they’d stepped into a miniature campus! Their teacher applauded them, saying, "You’re thinking just like real architects!"

Grade 4 Maths PBL

Our grade 4 became "Eco-Detectives," using their knowledge of decimals to investigate leftover school lunches! Working in small groups, students measured and recorded the weight of uneaten food daily. They then organized and analyzed the data, applying decimal operations—addition, subtraction, comparison, and unit conversion—to calculate daily waste. Together, they created clear bar graphs to visualize the weekly trends.

But they didn’t stop there! The students launched a "Clean Plate Campaign," designing a reward system where classmates who finished their meals earned a special maths-themed currency called "YWIES Dollars."

Through this project, students not only strengthened their skills in decimal maths and data analysis but also developed teamwork: some were in charge of weighing and recording, others handled data organization, and others designed charts. Most importantly, they discovered that maths isn’t just abstract textbook knowledge—it’s a powerful tool for solving real-world problems!

Grade 5 Maths PBL

Over the past month, our grade 5 became "packaging detectives," using their mathematical skills to solve real-life mysteries! Armed with rulers and calculators, they investigated supermarkets and homes: measuring the "nesting doll" volumes of mooncake gift boxes, comparing the packaging efficiency of bulk snacks, and uncovering the secrets of excessive packaging.

In the "Smart Packaging" challenge, students designed space-saving stacking solutions, optimized surface area calculations, and even applied science class materials knowledge to create eco-friendly packaging. We hosted a campus packaging design competition—crafting the "most beautiful outerwear" for everyday items with creativity. Their designs not only calculated paper usage precisely and incorporated innovative technology but also promoted environmental awareness!

This interdisciplinary project combining maths, science, and art helped students realize through collaboration: Packaging isn’t just a rectangular prism in formulas—it’s a practical art form that blends frugal wisdom, functional aesthetics, and innovative thinking!

At the Maths Week exhibition, every child’s design was a "trendsetting eco-friendly package"！

Maths Carnival

Meanwhile, we also held a maths carnival, where the sports centre became a "Maths Playground."

Students experienced a wide array of engaging maths activities: Maths Spin the Wheel, Maths Puzzles, Maths Crafts, Maths Programming, Maths-themed Beanbag Toss, Maths Bowling, Family Challenge, Maths Theater, Maths Board Games, Fun 24-Point Game, Maths Experiments, and Supermarket.

Through this engaging PBL approach, students have not only flexibly applied abstract mathematical concepts to real-world situations, but have also developed hands-on skills, teamwork abilities, logical thinking, and learning motivation through the process.

The students genuinely discovered through hands-on experience: "Maths can be so lively and fun!"
