A tally is one mark for each answer. So you do not recount the pile.
Step 1 of 5
- An empty tally.
- One mark.
- Four marks, standing up.
- The fifth mark crosses the first four.
- Two more marks. 5 + 2 = 7.
A tally counts in bundles of five. A bundle is five marks together.
- Four marks stand up. The fifth mark crosses them.
- Count each bundle as 5. Then add the loose marks left over.
- Two bundles and two marks: 5 + 5 + 2 = 12.
