Directed Numbers Mystery
This resource written by Shirley Fall has thirteen cards each with a statement about directed numbers and how they lie on a 3 by 3 grid. The rationale is for students to discuss possible options and work towards a solution of which directed number lies in each of the grid cells.
The file named Directed Number Mystery Solution has a solution to the mystery, the solution can be cut up into cards and used as support material if needed.
A blank 3 by 3 grid is available as separate file and it is recommended to enlarge this to A3 size. The mathematics students will need: Addition and subtraction of directed numbers, odd and even numbers (integers). Teachers' notes including some solutions are in the background information for this collection.
