Data & Tally Charts — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. The list red, blue, red, green, red, blue has 3 red items.
Reading through the list we find the word red three times, so red gets three tally marks.
2. From the same list, blue appears 2 times.
The word blue shows up twice in the list, so the blue row needs two tally strokes.
3. Green appears 1 time in the list red, blue, red, green, red, blue.
Green is written one time, so its tally row has a single upright line for one.
4. The color with the most tallies in the list is red.
Red has three tallies, which is more than blue's two or green's one, so red is the most.
5. Altogether the chart has 6 tally marks.
Three red plus two blue plus one green equals six, matching the six items in the list.
6. If one more blue is added, blue's tally total becomes 3.
Adding one to blue's two existing tallies makes three, tying blue with red in the chart.
7. A list of 5 cats and 2 dogs gives the cat row 5 tally marks.
Five cats are drawn as four upright tallies crossed by a fifth slanted stroke, showing five.
8. The dog row in that same pet list shows 2 tally marks.
There are two dogs in the list, so the dog row has just two straight tally lines.
9. When making a tally chart we put one mark for each item we count.
Tally charts add one stroke per item so the total marks always match the number counted.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Red tallies in red, blue, red, green, red, blue
→ 3
3
Blue tallies in the same list
→ 2
2
Green tallies in the same list
→ 1
1
Total items in that list
→ 6
6
Matching each color to its tally count practices careful sorting and accurate chart building.
