Data & Tally Charts — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Two full crossed tally groups written as a number equal 10.
Each crossed bundle counts as five, so two full groups add together to make ten as a number.
2. The number 15 drawn in tallies needs 3 full crossed groups.
Fifteen equals five plus five plus five, so we draw three full crossed tally bundles to show it.
3. One crossed group plus 3 extra strokes equals the number 8.
A crossed bundle counts as five, and three extra upright strokes add three more, giving a total of eight.
4. The number 12 in tallies is two crossed groups plus 2 extra lines.
Two crossed bundles total ten, so we add two extra upright strokes to reach the number twelve.
5. Three crossed tally groups written as a number equal 15.
Five plus five plus five equals fifteen, so three crossed bundles always stand for the number fifteen.
6. The number 9 in tallies is one crossed group plus 4 extra lines.
Nine equals five plus four, so we draw one crossed bundle and add four upright strokes beside it.
7. Four full crossed tally groups written as a number equal 20.
Skip-counting four bundles by fives gives five, ten, fifteen, twenty, so the number total is twenty.
8. The number 6 in tallies is one crossed group plus 1 extra line.
Six equals five plus one, so we draw one crossed bundle and add a single upright stroke beside it.
9. To go from tallies to a number we skip-count the bundles by fives.
Every crossed bundle counts as five, so skip-counting by fives is the fastest way to find the total.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
One crossed group plus 2 extra lines
→ 7
