Geoboard Squares

In this Bowland task, students are presented with a picture of a geoboard - a number of nails arranged in a square lattice on a board. On the lattice there is a sequence of squares. Students are told the length of the side of each square, the number of nails on the edge of the square and the number of nails inside the square. They then explore connections between these variables using other sizes of squares. 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.
