In this engaging hands-on math activity, students become mini-engineers by building pipe models using pieces with specified lengths in fractions and decimals.
They are given a set of “pipe” segments labeled with measurements like 1.25 m, ¾ m, or 0.5 m. Students must calculate total lengths to form a specific pipeline length by adding and comparing fractional and decimal values.
This task strengthens their skills in converting between fractions and decimals for accurate computation. It also helps them understand real-world applications of measurement, such as plumbing or construction. Group collaboration encourages problem-solving and mathematical communication. As a challenge, they plan the most efficient way to use the available pieces without wasting any length.
The activity ends with a reflection on which math strategies worked best and why accuracy is important in real-life construction.
