### Lesson 11.2 Read and Interpret Picture Graphs

**Explore and Grow**

How are the graphs similar? How are they different?

Each â—‹ = 1 counter.

Answer:

The First picture is the Tally chart of Yellow and Red color counters.

Tally chart marks are a quick way of keeping track of numbers in groups of five. One vertical line is made for each of the first four numbers; the fifth number is represented by a diagonal line across the previous four.

In this tally chart we see Red color shows group of five counters and another 1 counter total = 5 + 1 = 6 counters.

Yellow color shows four counters with four vertical lines.

The second graph is the Picture graph. AÂ picture graph, orÂ pictograph, is aÂ graphÂ used to display information that uses images or symbols to represent data.

In this each counter is marked as â—‹. In this picture chart we notice the red color counter has 6 counters marked with 6 â—‹.

In the yellow color we have 4 counters marked with four â—‹ .

In both the charts the representation is different from each other .
