Correct! We must sort items by color or type before we can count them properly.
Which of these helps us sort items into groups?
Exactly! We look for attributes like color, shape, or size to group things together.
Can we sort the same pile of buttons in different ways?
Yes! Data can be organized in many ways depending on the story we want to tell.
How do we write a "gate" of five using tally marks?
Perfect! The diagonal line makes it easy to count groups of five very fast.
Why do we use tally marks instead of just writing numbers right away?
