PT 5-8 - Math Talks
http://www.mathtalks.net/pt-5-8.html
I don’t know the equation but I think I can build it. For step 43, you’d build 43 triangles on the bottom layer, then 42 on top of that, then so on and so forth until 1 at the top. I know the perimeter is always 3 times the step number. But I don’t know how to find the toothpicks inside the perimeter. I used a table of values and got (n 1)(n/2) for the number of triangles. Then multiply this by 3 because each triangle has 3 toothpicks. Isn't what Student 3 shared the Gauss equation? I see a square of (n)...
PT 17-20 - Math Talks
http://www.mathtalks.net/pt-17-20.html
Holy cow. Students had more ways to see this pattern than any other so far. I had to extend the talk over two days because we’d already used up 20 minutes of class on the first day! I’ve been calling on students (first 3 at random) to share the equation if they have it, then I ask the class to try to see where each term in the equation comes from. I see the perimeter as 4 groups of (n-1), plus the 4 corners. Then I see these diagonals inside [brown] — there are always 3 groups of (n-1). I see the pattern...
PT 25-28 - Math Talks
http://www.mathtalks.net/pt-25-28.html
I see the shape as 2 halves, top and bottom. For each half, I see n groups of 3. But the groups overlap, and the overlap is always (n-1). My equation is H = 2(3n) – 2(n-1). I see the two middle rows of hexagons of (n 1) each. Then there are leftover groups of n on top and bottom: H = 2(n 1) 2n. I see n groups of 6. But there are (n-1) overlaps of 2 each. My equation is H = 6n – 2(n-1). Similar to how Student 1 sees it, but she creates 2 separate rectangles instead of 1. I see 2 squares and 1 rectangle:.
NT 13-16 - Math Talks
http://www.mathtalks.net/nt-13-16.html
Top menu: NT = Number Talks PT = Pattern Talks (hover over NT to see). 13 Which two are closer: 3 2, 2 3, sqrt(72)? I think 3 2 and 2 3 are closer because I know these are 9 and 8, and I don’t know what sqrt(72) is. I know sqrt(72) is between 8 and 9 because 8 2 is 64 and 9 2 is 81. Well, 72 is 8 away from 64 and 9 away from 81. So sqrt(72) is closer to 8. 14 Which is greater, 65 x 47 or 67 x 45? I think they are equal because 67 minus 65 is 2, and 47 minus 25 is also 2. When I asked why her confidence w...
PT 9-12 - Math Talks
http://www.mathtalks.net/pt-9-12.html
Kids didn't see the color version of this pattern, but in black and white, there was enough shading to make the distinctions. I see 2 squares. The top right square is n by n. The bottom one is (n 1) by (n 1). But I have to subtract 1 because they share this circle. My equation: C = n 2 (n 1) 2 – 1. I see the top square like Student 1 did. Then I see this rectangle of (n) by (n 1), and the left over part is always n. Equation is C = n 2 n(n 1) n. I see the whole thing as one big square of 2n by 2n. Horizo...

7 Deadly Sins of Teaching [Maths]. October 27, 2016. I did my first webinar last week as a precursor to my talk at NCTM’s Innov8 Conference. Next month. I thought it went okay — or horribly — just tough to be the only person with the mic and not being able to actually see the attendees. It was weird. There are a few slides from the webinar that I’d like to share here mainly because I’m still thinking about them and writing anything down helps me set the wobbly gelatin. I bring up the private school and m...

Teachers - Visual Patterns
http://www.visualpatterns.org/teachers.html
Uring 2013-2014, I used visual patterns with my students two days a week as part of our warm-up routine. I shared our "pattern talks" at MathTalks.net. Ne way to assign the patterns. By the way, I wrote a post. About doing a visual pattern with kids the first time.). I use Randomizer.org. To help me quickly and randomly assign the patterns to students. The generated list can be opened in. You could give kids a form like this to fill out:. Sheri Walker shares her modified version of form.

Math Talks - NT 1-4
NT = Number Talks PT = Pattern Talks (hover over NT to see). 1 Are there more inches in a mile or seconds in a day? I thought there were 2000 feet in a mile, but I realized I was wrong when I talked with my neighbor. 60 x 60 = 3600. I changed 5280 to 5000 and 12 to 10. Multiply 5000 with 10 to get 50000. Then I multiplied 280 times 2 to get about 500, add a 0 to this to make 5000. So there are about 55,000 feet in a mile. To figure out the time, I changed 24 hours to 20; and 20 times 3600 is 72,000.
