TLF ID M025305
This sequence of two lessons explores the concept of statistical variation. Students make licorice logs both by hand and by using a Play Doh machine. They record and compare the attributes of both types of licorice by plotting their findings and comparing the shapes of the two plots. Students are then challenged to produce identical licorice sticks. They experiment with strategies to restrict variation and consider the importance of maintaining consistency. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and student resources. This sequence is part of the reSolve: Maths by Inquiry program.
