Six two-step word problems set at a wildlife park for Year 4 maths. Pupils add visitor numbers from two schools, track ticket sales against a total of 1,500, follow Sam along a 2,500-metre trail, and finish with an extra challenge that includes checking someone else's working and ignoring a red-herring number. Detailed solutions are included. Matches the England National Curriculum objective on two-step problems in context.
