1. Math Graphs

2. Tally Chart Tally charts help people count. Each tally mark in a tally chart represents one object. For example, to count three smiley faces, you make three tally marks in the chart. Tally marks are grouped in sets of five, which makes counting easier. Instead of counting marks one-by-one, you can skip-count by fives and add on any remaining marks. Color of Smiley Faces Number of Balls TallyFrequency red/1 orange///3 green////5 blue//2 black0

3. Length of Calls in Minutes Number of Calls TallyFrequency 3/1 4///3 50 6//2 7////5 8//// //7 9////4 10/1 Tally Chart Look at this tally chart. How many 7 minute phone calls were made? 5 phone calls How do you know? There were 5 tally marks in the 7 minute row so the frequency was 5.

4. Line Graph Line Graphs can be used when you're plotting data that has peaks (ups) and valleys (downs), or that was collected in a short time period. This line graph shows how many children were in the 6 th grade over the past 5 years.

6. During how many years did Beth travel more than 4 times? 4 years In which years did the number of trips increase? 1997 – 1998 In what year did Beth travel the least? 1995

7. Draw your own Line Graph Here is the information for your line graph. Last week, Brians school had snow days all week long. Here is how much snow fell each school day last week. On Monday 4 inches of snow fell, on Tuesday, 2 inches of snow fell, on Wednesday 4 inches of snow fell, on Thursday 6 more inches of snow fell, and on Friday 1 inch of snow fell. Dont forget a title for your graph. Remember to label!
