"Why are we learning this?"

A7. Notice names with numbers attached. Names seem to be in alphabetical order. Wonder if there is a pattern or reason for numbers connected to each name. #ElemMathChat

A5: We did frayers a lot. Most of the time on a shared slide so kids could "cheat" and see each other's work. Review I used Gimkit to make it fun. Kids would also create the Review questions so they had to write/punctuate/spell correctly. #ElemMathChat

Hands down one of my favorite routines. And most of my kids beg to do them.

What a great idea. Using similar strategies across subjects makes planning easier for the teacher but relieves students of having to navigate different learning routines. Win win.

Just saw 5 Fingers on a hand and 18 holes on golf course. But the rest still haven't materialized.

A4: I used to use pictures to generate 8 parts of speech and writing. Estimysteries pictures, collections/jars could easily be re-used for writing/storytelling #ElemMathChat

Yes. I imagine perspective, experience and current reality push us heavily. With recent meetings I'm wondering if the one is 18 hits on the Google Calendar 😁 #ElemMathChat

Took me way too long to get 5 toes on a foot. But with as many teeth as my son has lost lately, 5 teeth on a fairy is probably more relatable 😅 #ElemMathChat

I also notice my typing (and phones autocorrect) are wildly off. 🤣 So many type-os. Guess I spend too much time with numbers now. #ElemMathChat

A2: I notice some of these jumpvright put as familiar. 26 letters of alpha, 7 days of week. But others are less known. #ElemMathChat

It's Mental Math Monday! How would you mentally calculate 15×24?

First thought was to break 15 into 10 and 5. But then I noticed both were great candidates for double/halve. 30x12 is easier but I repeat the d/h to get 60x6. Now I'm working with a known square 6x6 is 36 and shift place value since it's 6 tens. 360.

Today I helped some teachers come to grips with the fact that their 4th grade math textbook has many lessons that are NOT 4th grade standards.

Not only does the book NOT advocate good teaching...it is also teaching the wrong stuff.
