Equal Parts: Pieces that look the same and are the same size (like twins!)
Unequal Parts: Pieces that look different and are different sizes
Whole: Something complete before we cut it up
Equal parts: All pieces look the same and are the same size
- Look at each piece
- See if they are the same size
- If yes, they are EQUAL
- If no, they are UNEQUAL
All three apple slices are the same size
They all look the same - like twins!
These are EQUAL parts
Yes! These are equal parts because all 3 apple slices are the same size. They look like 3 little brothers!
• Equal means same: Same size, same shape
• Look and compare: Use your eyes to see
• Twin test: Would they look like twins?
Unequal parts: Pieces that are different sizes
One is big, one is small, one is medium
They are all different sizes - not like twins!
These are UNEQUAL parts
Right! These are unequal parts because the cake pieces are different sizes. One is big, one is small, and one is medium!
• Different sizes: If pieces look different, they are unequal
• Size matters: Bigger pieces vs smaller pieces
• Fair sharing: Equal parts help share fairly
Fair sharing: Only works with equal parts
There were 4 equal slices
3 slices are left
3 out of 4 slices are left
No, we can't share fairly if slices were different sizes
Good job! 3 out of 4 slices are left. No, we can't share fairly if the slices were different sizes because some people would get more than others!
• Fair sharing: Needs equal parts for everyone to get the same
• Counting: How many parts total? How many left?
• Equality: Fair means everyone gets the same amount
Sharing fairly: Means everyone gets the same amount
One tiny, one big, one medium - all different!
They are definitely different sizes
No, these are unequal parts
This wouldn't be fair for sharing - someone would get more!
Correct! These are unequal parts because the scoops are different sizes. When sharing, equal parts make sure everyone gets the same amount and no one feels sad!
• Different sizes: Mean unequal parts
• Fair sharing: Everyone gets the same
• Happy friends: Equal parts make everyone happy
Fair sharing: Happens when all parts are equal
2 equal pieces - perfect for 2 kids!
3 pieces but different sizes - unfair!
First cookie can be shared fairly
Equal parts mean everyone gets the same amount
Perfect! The first cookie can be shared fairly because it has 2 equal pieces. The second cookie has pieces of different sizes, so sharing wouldn't be fair - some kids would get more than others!
• Equal parts: Allow fair sharing
• Different sizes: Make sharing unfair
• Happy sharing: Everyone gets the same amount
Equal Parts: Look like twins - same size, same shape!
Unequal Parts: Look different - like cousins!
Fair Sharing: Everyone gets the same amount
- Look: Use your eyes to see the pieces
- Compare: Are they the same size?
- Decide: Equal or unequal?
- Think: Is this fair for sharing?
• Twin Test: Would pieces look like twins? Then they're equal!
• Eyes Test: Look carefully with your eyes
• Fair Test: Can everyone get the same amount?
• Size Test: Same size = equal, different size = unequal
