Watch Carefully!
Guess My Rule
Your teacher is sorting objects right now.
Watch carefully. Do NOT say the rule yet — just think it!
What rule is the teacher using?
When you think you know — put your hand on your head quietly!

Lesson 1
What Is Sorting?
Sorting means putting things into groups that go together.
Every sort has a rule.
The rule tells you WHY things go in the same group.
- Rule: sort by COLOR → red things together, blue things together
- Rule: sort by SIZE → big things together, small things together
- Rule: sort by SHAPE → round things together, square things together

Lesson 1
Our Sorting Rules Today
Same objects. Different rules. You get DIFFERENT groups each time!
6 / 15
Lesson 2
Does It Belong?
Every object goes in the group where it belongs — where the rule fits!
Belongs here!
- Big red button → BIG group
- Small blue block → SMALL group
- Round coin → ROUND group
But wait…
- If rule is COLOR: big red button → RED group
- If rule is SIZE: big red button → BIG group
- Same object, different group!

Activity Time!
Let's Sort!
Get your bag of objects. Here is what you will do:
- Sort #1: Sort by COLOR. Put each color group in its own area. Label it!
- Gallery walk — look at other sorts
- Mix ALL objects back in the bag
- Sort #2: Sort by SIZE. Big / medium / small.
You have 10 minutes for each sort. Ready? Go!

Sort Helper
Stuck? Ask Yourself…
- What is my rule? (Look at the rule card!)
- What attribute does THIS object have?
- Which group matches that attribute?
- Put it there and move to the next one!
If something does not fit any group — make a new group! That is okay.
9 / 15
Gallery Walk
Look at Other Sorts!
Walk around the room. Look at other pairs' sorts.
- Look at their groups — can you tell their rule?
- Did anyone sort differently than you?
- Does any object surprise you — why is it there?
No touching other pairs' objects! Just looking.
You have 2 minutes!
10 / 15
Brain Break — YOU Are the Sort!
Your teacher will call a sorting rule.
Move to the right side if you fit — left side if you don't!
Examples: wearing something red · have laces · have a pocket
You just sorted YOURSELVES like data!

Debrief
What Did You Notice?
- Did the same object end up in different groups for Sort 1 and Sort 2?
- Which sort was easier? Why?
- What would happen if you changed the rule AGAIN?
- Did any pair sort differently than you?
The rule is what changes the groups — not the objects!
12 / 15
Worksheet Time
Draw Your Sorts
On your worksheet:
- Draw Sort #1 — show each group, write the rule
- Draw Sort #2 — show each group, write the new rule
- Write the name of each group (the category)
You can draw simple shapes or circles to show the objects — you don't have to draw them perfectly!

Great Work!
Session 2 Done! ⭐
- We sorted objects using a rule
- We sorted the SAME objects in a DIFFERENT way
- We saw that the rule decides the groups
- We walked around to see other ways to sort
Next time — Session 3: We will COUNT how many are in each group!
