110 Years On
This assessment task from Bowland asks students to use mathematical reasoning to estimate the number of descendants a girl who lived 110 years ago might have today. The key processes involved are representing, analysing, communicating and reflecting. Students are given a number of basic facts upon which to base their solution. Teacher guidance includes concepts which may be discussed with students, examples of probing questions which may be useful and assumptions that students need to make when completing the task. The assessment guidance consists of a progression table detailing how students may improve in each of the key processes. The resource concludes with a number of examples of students' work, together with comments, probing questions and feedback.
