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.
Welcome everyone! Tonight I am going throw out slides quickly. Hang on to your seats! Remember to include #elemmathchat in all of your tweets & responses
Hi Everyone, Tika, from Las Vegas, NV. I am a fifth-grade teacher and teacher mentor. My favorite song from my teens is any @BonJovi song. #elemmathchat
A1 The shaded part is 3/4. I found this by looking at the original shape labeled "1" & found that the sharded part is missing a square portion or 1/4 of the original 1 whole. #elemmathchat
Is this picture all one whole? Or are we supposed to"see" what is behind the front part? If that is the case 1/2 o the second figure is shaded. #ElemMathChat
Are we identifying the shaded part of all of those quadrilaterals, or is the middle under the 1/4 piece and on top of the one behind it? Are we seeing 2-D or 3-D? #ElemMathChat
Q8: I think I need some paper and pencil now....36 in each box and need to explore the dimensions closely. Maybe a bigger ohone screen would help 😲#elemmathchat
#elemmathchat
That’s actually exactly what we did.
We didn’t have enough orange 10 rods. We only had 12 rods. So I asked how many more would we need.
Someone said 1000 in total. Someone said 100. Others said 88 more.
Those are really different numbers though
#elemmathchat
A8: A tough one! I assume it's 2 rows up and 3 boxes deep. The bottom layer is full with 5 x 2 x 3 = 30 boxes. The top layer is 3 + 1 + 2 +...idunno... I'd say around 36 ish there. Unless it's 4 boxes deep. #elemmathchat
Q8 this is a tough one. I’m skeptical that all the boxes we can’t see are there, but assuming they are I count 4 deep, so 16 on the bottom plus 8 more on top, with 8 missing?#elemmathchat
That's kinda what I figured. And I assume most people (young and old) would think that. Except for those currently studying decimals! What if you were studying decimals in class? #ElemMathChat
Yea, just like we want students to be flexible with the whole for fractions, we want that to be true of decimals, too, though I see it less with decimals (wonder why). What if the "flat" represents 1? What if it represents 1/10th? #ElemMathChat
4x6 is more than 5x4. You could cut out animal figures or use counters in a pattern or have the students create their own and share with a partner. #ElemMathChat
Thanks @MissMath_Teach ! I have to slip away for kiddos bedtime but loved all the questions so far! So many accessible and open ended otems to get kids feeling safe to talk about math! Thanks! #elemmathchat
Okay, I had to go play with this math for fun. I see a squared pattern. Pattern 1 = 1^2, 2=2^2, 3=3^2 so 10 would be 10^2 = 100 I wanted to create a color code picture to show the pattern growth, but I realized this would take a long time to color! #ElemMathChat
A12 9 polygons, Is it 7 or 8 trapezoids? Can I combine the triangle and parallelogram to make one? If so then are there 4 hexagons? 24 Triangles ..... Lots more cooolio things too! #ElemMathChat
A14 degrees, both temperatures and elevations, miles, feet, percentages of humidity, UV ray rating, sea level, pounds of the backpack or person, clothes and shoe size, rock hardness.... #ElemMathChat
Right! That's my thought. First @MissMath_Teach with "less than I had in a week" now @MFAnnie with 5 days of dessert. I am opening this chocolate box in the fridge now. #elemmathchat
