Adding and Subtracting 17,18,19
Pupils use their Enrich school orienteering maps to locate specific control points. At each one, they record the 3rd and 4th numbers from the control marker. They combine the two numbers to make a two-digit number and then add and subtract either 17,18 or 19 from this number.
