Elementary math chat is a weekly math chat where participants come to discuss best practices, examine student work, explore routines for reasoning and research that guides and supports pedagogy centered on problem and student based learning.
We will use the usual Q1/A1 format tonight. please remember to let everyone know which prompt you are referring to, and as always don't forget the #ElemMathChat
Hi #elemmathchat! Annie, instructional coach in k-8 district in Berwyn IL (Chicago area). My fav place to be is with my family, even though I have 2 crazy kiddos ages 3 & 1 (exhausting!) 😆
I'm Melynee in Claremore, OK I teach math for 6-8th grade Ss with disabilities. My FAVORITE place to be is on the beach looking for seashells with my family! #ElemMathChat
Hey #elemmathchat Michelle, Instructional Coach
Curled up w/ blanket on couch eating rice with coconut curry sauce! Fav place to be? Beside whoever I am with!
Q1: Dot A is 90 and Dot B is 125. Thinking about the distance between 75 and 100 and made an estimate. For Dot B, I used the number line above. #ElemMathChat
Hi Margie - My week - today we did some stinking awesome problem solving. I have also been afraid for student safety this week sooooooooo My week has been the great, the bad, and the ugly #ElemMathChat
A1 A about 92 looks to be 2/3 of the way to 100 from 75. For B, if scale is same as A, then confident in 125 but don't know if scale is related to A or a separate one. #elemmathchat
A1 dot a is at around 90 (just more than halfway between 75 and 100). If the two sets of dots are the same distance apart then b is 125. Otherwise it could be any number greater than 100 #ElemMathChat
A1: oh, interesting. I think you need 2 points to be able to tell.
On line A, I estimate 93.75 (3/4 of way past 75 before 100). On line B, it really could be anything! Assuming same scale as line A, I would say 125, but if it’s not same scale, who knows! #elemmathchat
A1: Point A, about 90. I’m picturing 3/5 of the way from 75 to 100. Point B I’m unsure. I wonder if the scale of the # lines is the same? #ElemMathChat
So I can't be 100% on dot A but it is more than half way between 75 & 100 Maybe 87-90? BUT is scales are same on both lines Dot B is at 125 because 25 places between 75 & 100 Same distance between 100 and dot #ElemMathChat
Great question! I think for this task the shape of the perimeter of the paper is irrelevant because you are cutting your shapes from the centre.
#elemmathchat
A3a: Made the rectangle by folding the paper into eights and cut parallel to fold line. Wondering if it would have worked if I folded into fourths. #ElemMathChat
3b Here are some that I did earlier. When you were trying, what did you find successful?
What were your struggles?
Try some more and tweet your results. I'll give you some more time.

A3b
After I was clear on the task, I was successful on making the triangle and the square... I made some rhombus figures as I was trying to make a rectangles... I just made 3 diamonds
#ElemMathChat
One cut per shape, one shape per piece of paper. Check my examples with triangle, octagon, pentagon and concave quadrilateral. Each was done with one cut.

A3 So it's late here in the east coast so I am in bed scissorless. So I tried to imagine a cut and draw where the cut would be on a random fold. As I unfolded, I noticed the cut on the "back" of each fold had to be a reflection of the front #elemmathchat

You attempted a triangle, got a concave quadrelateral. What could you alter on your next attempt to get a triangle?

Q5: Would a spatial representation be a bar diagram. I would draw the 3 meters and then another bar under dividing the wholes into fifths. Thinking I need to use all this scrape paper to make my model. The abstract would be the expression. #ElemMathChat
A5 a spatial representation could be with cuisenaire rods or fraction strips. Abstract could look like representing 5 as 25/5 & finding how many sets of 2/5 #ElemMathChat
6A I think the second one. Two holes on the bottom, close together and then 2 more about 2/3 up? (I can't see it anymore) on the outside edges. #elemmathchat
It is like being in a faculty meeting and everyone is talking at the same time at their tables (pet peeve) and someone is trying to present! You just gotta find your "table" and chat it up - It's okay on Twitter! Glad you are here! #ElemMathChat

A6d: I would love to punch some holes in paper and see who can stump who? Can they make the visual end before unfolding? (This as a challenge) #elemmathchat
