Which fruit do most friends like?
Sari asks nine friends which fruit they like best: mango, banana or papaya. They all shout at once, and she cannot remember who said what. Which fruit do most friends like? She needs a way to count the answers and show them. By the end I can record with tally marks, build a block graph, and say what the answers show and how sure I am.

A peek inside
Sari asks 9 friends to choose mango, banana or papaya. Build the block graph with one block for each friend.
Count each answer: mango 4, banana 3, papaya 2.<br>Check 4 + 3 + 2 = 9, so each friend gets one block.<br>Stack 4 same-size blocks, then 3, then 2, with no gaps.<br>Add a title and labels: mango 4, banana 3, papaya 2 blocks, so 9 blocks altogether.
Try this at home: Sari asks 9 friends to choose mango, banana or papaya. Build the block graph with one block for each friend.
