Last summer I shared the site Mathigon.org as a new "textbook of the future". More recently, I have started to use their virtual manipulative repository Polypad. There is so much here - algebra tiles, fraction tiles, prime factor circles, customizable spinners and so much more. You can create a class and share things within your class and via Google Classroom (among other places). Just check out their YouTube channel for all kinds of ideas.

Having good math starters is a great way to keep students engaged. @SteveWyborney has a lot on his site and one he calls Esti-mysteries. I like them because not only are they low floor because all kids can estimate but then he goes on to give clues based on the answer so kids can start using their mathematical skills to refine their guesses. Totally check them out but @RNHung has turned a bunch of them into a @Desmos activity so take a look at that too.Creating = ratios with an @openmiddle theme. How many proportions can we create? Which digit(s) are not as user-friendly as others? Why? 🤔 https://t.co/NJfqzTypUg @geogebra @robertkaplinsky #MTBoS #ITeachMath #math #ElemMathChat #MSMathChat pic.twitter.com/4od6OQ04JO

The BEST conversations in breakout rooms this year. Esti-mystery tasks are all created by middle school students, bundled into a @desmos activity. Thank you @stevewyborney @mr_stadel @edcamposjr @Cbustamante2222 #FAME20 @maeputt #teach180 https://t.co/Yz8bSqt2yA pic.twitter.com/IF4LXP8WE7

Pi Day is tomorrow. Here was my attempt, a few years ago, to explain what all the fuss *should* be about. https://t.co/0p8Z7fpWOV

People calculate the weirdest things. Which celebrity based on their date and location of birth, was most likely to have been conceived at the 1969 Woodstock festival? Apparently the answer is Tina Fey. Source: https://t.co/UfkeiZa3JA pic.twitter.com/SAyEGGnt0V

A simple premise but definitely some good problem solving needed to determine the answer here.

It's already pi-day in some parts of the world. So here's tomorrow's puzzle now: a tweak on a classic. 10 cm of perimeter length added to a square, an equilateral triangle, a circle. Which has smallest gap width? [Or am I being foolish: it all depends on the sizes of the shapes?] pic.twitter.com/rKU7tXcwJc
