Farmyard FriendsTask 129 ... Years 2  10SummaryFive animals have to be placed into five pens according to the restrictions of the problem. This language and logic puzzle entices students through the use of toy animals. Also, it doesn't seem too difficult because there isn't much writing on the card. However, it is exciting to discover that there is more than one solution and this opens the door to a rich iceberg of possibilities that can extend into the senior years of high school.

Even quite young students usually have no problem finding one solution to this puzzle, but the challenge is in finding more. The words 'the end' and 'after' can be interpreted in various ways, eg:

Whole Class InvestigationTasks are an invitation for two students to work like a mathematician. Tasks can also be modified to become whole class investigations which model how a mathematician works. 
Introduce the investigation using students to act as the five animals.

Also write out the clues large enough for all the students to see. The upper section of the whiteboard will do the job here. The investigation begins with the class telling the animals the order in which they should stand. Once the solution is found encourage each student to record it in their journal and then surprise them with ... Guess what. There is another solution. Ask the students to quickly rip up paper and write the animal names (one set between two) and use these to find and record it. Encourage students to ask:
