New updates on the Mathies Pattern Blocks app. That is, they have added some new shapes. The dart, the kite and the right angle are all part of the 21st Century Pattern blocks found on the Talking Math with your Kids site. Now there are a pile of options when you have your kids build with the pattern blocks. This is just the development version so I'm not sure when you will see it in the public version but you can play right now with the link below.

When we were at #NCTM2019 in San Diego this year the funnest way to get around the city was on these electric scooters. Well @MrOrr_Geek with the help of @mathletepearce has created a 3Act Math task. Watch a video to pique students interests. The video shows a split or POV riding with the app screen. Then you can use linear relations tools to figure out the total cost of the trip.

Have your kids give this a try. Take the parabola y=x2 and pick two points on the parabola. Multiply the x values of the points and the product turns out to be the y intersection of the line connecting the two points. Why not try to investigate why this works?

In classic "parabolic multiplication" to compute axb: go a units L on x-axis, b units R, find corresponding points on y=x^2 & connect. Read off product on y-axis. Picture shows 2x3=6. a) Why does this work? b) Possible to compute (-2)x3 too via this model? c) How about (-2)x(-3)? pic.twitter.com/gBZ8dkbopE— James Tanton (@jamestanton) June 22, 2019
Have you heard of the Tribonacci sequence? How about the Rauzy fractal? Well I can say that I have played with the tiles that @Gelada shows here but I didn't know all the other stuff. So fun
