Teaching tip: Here's how I spice up the activity "Which One Doesn't Belong?"

[Michaela Epstein @MathsCirclesOz]

A neat puzzle-

1. Shade any 2 sections
2. What fraction of the square is shaded?
3. What other fractions are possible? Impossible?

This puzzle kicked off discussions at a workshop for PD Hub members.

How can we visually show why something like sqrt(90)=3sqrt(10)? Rewriting square roots can be seen visually!

(I know the title doesn't sound appealing but I honestly really like the concept lol)

2 years ago, I received a 17 page Google document of teachers who participated in a book study for Chasing Rabbits in Colorado. Sometimes, you have no idea as to the power of the words you put together. @HumResPro @eureka_math

When subtracting from a number that ends with a lot of zeros, consider subtracting 1 from both numbers so we don't have to "borrow" several times.

@edukings @PoudreSchools Isn’t she just the most amazing teacher??? Sue changes what kids (and adults) think math is. She engages them in deep thinking and reasoning.
