Justify with Uncle Si!

Focus on JUSTIFYING for REASONABLENESS is going to be HUGE!

This part of the standard is identical K-4:
Justify his or her thinking using objects, words, pictures, numbers, and technology.
Justify
STUDENT THINKING
Including, but not limited to:
• Objects
• Words
• Pictures
• Numbers
• Technology
Use
LOGICAL REASONING 

When I was searching for this standard, I typed in the word "Justify" on the VADs and found that it was listed this many times:

• Kinder-4 times
• 1st-3 times
• 2nd-7 times
• 3rd-12 times
• 4th-11 times

We will make an Uncle Si poster for anyone that is interested.

Maybe we could have it as a quick 2 minute morning routine? Or maybe it could be added to 1 question on the daily review? Brainstorm ideas with your group about how to use this in your current IFDs. Please SHARE any ideas that you have!
We can make sure to let Si be RIGHT every now and then so that the kids really have to think and justify whether it is reasonable or not.
The hard ones to come up with are the ones that aren't easily identified as wrong, which is of course what was hardest for our kids on STAAR.
Here are a couple to help get us started:
-A clock that has the minute hand right but not the hour hand (or other way around)
-A number sentence that is SOLVED but using the opposite operation:
 20-15=35 or  12x6=2
-A number that is represented with based ten blocks but with the place value switched:
l l l l . . .
34
Here are some more ideas from the Math meeting this week:

It's not just for Math!!!
Thanks to Mrs. Whitaker I realized that this could work for any subject, just as a tool to get them to think deeper:
Examples for ELA:

-I can spel Jack!

-I predict that Jack and Annie will be in the dinosaur age.
 

-The mushers were required to possess these items during the race or they would be disqualified.
synonym for possess:
own
We would hope the kids would say NO because just because you own something, doesn't mean it is in your possession. And just because something is in your possession doesn't mean that you own it.
