I can use tally marks to help count votes and other numbers. For example:
= 13 votes
I know that facts and information can be called DATA
I can collect and organize data using a tally chart or a list. For example:
Class Shoe sizes: 2, 3, 2, 4, 3, 3, 5, 4, 3, 2, 4, 3, 5, 3, 3, 3, 4, 5, 2, 2, 4

I can solve problems by reading a bar graph. For example:
1) What is the most popular shoe size? Size 3
2) What is the least popular shoe size? Size 5
3) How many more size 3s are there than size 4s? 8 – 5 = 3 more size 3s.
