Reading times in minutes are 5, 6, 6, 7, 7, 8. Draw a labeled dot plot. Check the number of dots.
5: 1 dot; 6: 2 dots; 7: 2 dots; 8: 1 dot; n = 6
Each observation contributes one dot; stack repeated values at their number-line position.

Standards 6.SP.B.4
LEARNING TARGET
I can construct and interpret a dot plot on a number line.
01 · LEARN
Build the idea
Draw an equally spaced number line and stack one dot per observation above its value. Repeated values stack vertically. Add an axis label with units and check that the dot count equals the data count.
Reading times in minutes are 2, 3, 3, 4, 5, 14. Draw a labeled dot plot. Describe a cluster or gap and report the count.
2: 1 dot; 3: 2 dots; 4: 1 dot; 5: 1 dot; 14: 1 dot; n = 6; low cluster and high isolated value
Each observation contributes one dot; stack repeated values at their number-line position.
