K-2 Directions: Look at the 4 numbers below. They are all related to each other, like your family. You can still find one that doesn't fit in though. When you find one, tell someone you are home with which one it is. Make sure you tell them why it doesn't belong. Post your thoughts in the comments below.
K-2 Challenge: After finding one number that doesn't fit in, try to find a different one that doesn't belong. Tell someone you're home with the reason why it doesn't belong. It should be a different reason than the first one!
3-5 Directions: Look at 4 numbers below. They are all related in some way, but you can justify why one of them doesn't belong with the others. When you figure out which one doesn't fit in, tell someone you're home with which one it is. Make sure you tell them why it doesn't belong. Then, using a different reason, try to find a different number that doesn't belong. Once you have, tell someone in your house the new reason why that number doesn't belong. Post your thoughts in the comments below.
3-5 Challenge: Come up with a reason why each of the 4 numbers doesn't belong in the group with the others! Tell someone you're home with and post thoughts in the comments section below.

ReplyDelete6 does not belong because it is even and the other numbers are odd. Also, 15 doesn't belong because it is two digits and the others are one.
9 does not belong because it is one digit and the others are two digits.
16 does not belong because it is even and the others are odd.
Great job commenting on both, Logan!
Delete41 is the only prime number
ReplyDelete9 is the only one digit number
16 is the only number with even factors
25 is the only factor of 100
Wow! I love your thinking, Rina. In addition to being prime, 41 is also different from the rest for another reason. Can you think of how it is different?
Delete16 doesn't belong because it is an even number.
ReplyDelete9 doesn't belong because it only has one digit
Nice job! Were you able to see how the 4 numbers were related?
Delete15 is the only that has tens.
ReplyDelete6 is the only odd number.

Hi Mariah, 15 is the only one with tens, good thinking! What makes a number even or odd? Does 6 fall into the even or odd category?
Delete-6 doesn’t belong because is an even number.

-16 doesn’t belong because it is an even number.
- 9 doesn’t belong because only have one digit.

DeleteHi Valerie, Good thinking. Can you think of more reasons?
ReplyDelete6 does not belong as it is the only even number
ReplyDelete15 does not belong as it is the only 2-digit number

Good thinking! Can you think of reasons why the other 2 do not work?
Delete9 doesn’t belong because it’s not part of 16+25=41
ReplyDelete41 doesn’t belong because it’s not part of 16+9=25
16 doesn’t belong because it’s the only even number

DeleteTyler, those are some great observations!
Delete9 does not belong because 16+25=41 and 41 does not belong because 9+16=25
ReplyDeleteWow! You saw the relationship between the numbers. Nice work!
Delete25 does not belong because it's the only multiple of 5.
ReplyDelete41 doesn't belong because it's not divisible by any number.
16 does not belong because it's the only even number.
9 doesn't belong because it's the only single digit.
Russell, good observations. 41 is evenly divisible by 1 and itself, but no other numbers. There is a name for those types of numbers. Do you know what they are called?
