@RepMGP MN needed you yesterday but instead of standing for human rights & human decency, you voted to increase funding for ICE’s domestic terrorism, currently in my city, coming soon to yours. You bent the knee and refused the call. And now someone else is dead. The North remembers.

It’s unacceptable to have another needless death in Minnesota, and it’s unacceptable to have elected officials, candidates, and administration officials continue to throw gas on this fire, or tacitly encourage assaults on law enforcement and anyone else. The situation is un-American and Secretary Noem needs to step down.

@howie_hua 10x24 is 240. 5x24 is half that. 240+120 is 360.

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

@howie_hua 5x5 is 25 25x3 is 75 2x2=4 75x4=150+150 75x4=300 300x3=900

It's Mental Math Monday! How would you mentally calculate 2×2×3×3×5×5?

@howie_hua 10. There is a quincunx of apples on the left. If you take the apple in the middle and move it to the right, you can make another quincunx. 5+5=10

How would you count these apples? I just want to see something.

@howie_hua 240 people is 30 groups of 8 people. 232 is one fewer group of 8, So 232/8 is 29.

It's Mental Math Monday! If there are 232 people and there are 8 people per table, how would you mentally calculate how many tables are there?

What are the great mathy picture books to read aloud? I'm thinking for the k-5 crew.

@pwharris #mathstratchat 15% of 50 = 15 x .01 x 50 15 x .01 x 50 = 15 x .5 Half of 15 is 7.5 10% of 50 is 5 5% of 50 is half of 5 or 2.5 5 + 2.5 = 7.5 15% is 6 2/3 of 100% 50 divided by 20/3 = 150/3 divided by 20/3 How many 20s fit in 150? 7.5

@howie_hua I know there are 12 twelves in 144, so there are 24 twelves in 288.

It's Mental Math Monday! Faith and Sarah want to know how you would mentally calculate 288÷12.

@pwharris #mathstratchat 20% is 1/5 so of 20 is 4 1% of 20 is 0.20. 19% of 20 = 4.00-0.20 19% of 20 = 3.80

@howie_hua A tenth of 5 is 1/2 and half of that is 1/4, so 15% of 5 is 3/4.

It's Mental Math Monday! How would you mentally calculate 15% of 5?

@howie_hua I see a relationship to 30 in both 15 and 240. 15 is one-half of 30s. 240 is eight 30s. There are sixteen-halves in 8 so there are sixteen 15s in 240.

It's Mental Math Monday! How would you mentally calculate how many 15s are in 240?

@howie_hua @TimBrzezinski I might also say 30% of 990 is equivalent to 30x990/100 990/100 = 9.9 30 x 9 = 270 30 x .9 is one-tenth of that, so 27 270 + 27 = 297.

@howie_hua @TimBrzezinski 10% of 990 is 99. Three 99s is 3 less than 300. So, 297.

It's Mental Math Monday with guest @TimBrzezinski! Tim wants to know how you would mentally calculate 30% of 990. Please share how you would do it in the comments.

@pwharris #mathstratchat I can't decide if this is the same method but... 125 x 32 250 x 16 500 x 8 1000 x 4 2000 x 2 4000 x 1

@pwharris #mathstratchat 125 x 32 if the same as 125 x 2^5 so... 125 250 500 1000 2000 4000
