Grade 6 students at St. Lawrence Catholic Elementary School launched into the new school year with a vibrant and messy math learning experience: "Slime Time" Math. The hands‑on activity transformed abstract fraction concepts into something students could see, touch, and memorably create.
Working alongside Math Facilitator Rob Welsh, students collaborated in small groups to follow a step-by-step slime recipe. Their first task was to measure each ingredient precisely using fractional quantities. Their second challenge pushed their thinking further: doubling the recipe, requiring students to apply fractional reasoning to real-life adjustments and problem‑solving.
“Before diving into the slime-making process, the class engaged in a discussion about the role of fractions in everyday life,” said Welsh.
Students examined how bakers measure ingredients, how construction workers divide materials, and how families use fractions to manage budgets and expenses.
“These real‑world examples helped students recognize that fractions are more than mathematical ideas; they are practical tools used in daily decision‑making.”
“This learning experience also aligned directly with the Ontario Mathematics Curriculum (Grades 1–8), Numbers Strand, focused on representing, comparing, and ordering fractions; understanding equivalency; and using fractional reasoning in real contexts,” Welsh noted.
“In particular, the activity supported Grade 6 Number Sense – B1.4, which emphasizes applying fractions in practical situations such as scaling recipes and solving problems involving fractional quantities.”
“When students see how math lives outside the classroom and how it’s used in kitchens, workplaces, and homes, they begin to understand its purpose,” added Teacher Caitlin Cunningham, reflecting on the experience.
“Activities like "Slime Time" Math make learning meaningful, memorable, and fun.”
