#MathStratChat Viewing a number line we see that it will take 2 to get to zero and then another 6.9 into the negatives. -6.9 is the result. Or, change it to 2 + -8.9 and then 2 of the 8.9 form zero pairs leaving -6.9.

At #EDcampBCCC this morning, I was inspired to give thoughts to how the new reporting order, core competencies, self-reflections through the use of metaphor, prompts and templates (with choice & sliding proficiency scales). "Weaving" with friendly language for parents/Ss too.

#MathStratChat Still triggering money with the 1/4, converted 7/20 to 35/100 so 25¢+35¢ = 60¢ so 0.60 or 6/10 = 3/5

#MathStratChat I think decimals jump to mind for this as 0.55 - 0.40 = 0.15 or 15/100 or 3/20 as soon as I did this, 11/20 - 8/20 looks easy too.

#MathStratChat Pam Harris To be different or to introduce another medium, let's think sandwiches. A 12 inch sandwich is a footlong. A third of it is 4 inches and 2/3rds is then 8 inches. So 11 inches – 8 inches is 3 inches or 3/12 of a foot. Is there a name for a 1/4 sandwich?

#MathStratChat 6 ÷ 3 = 2. Since we are starting with 3/4 less than 6, we will have an answer that is 3/4 ÷ 3 less than 2. And 2 – 1/4 = 1 3/4

#MathStratChat partial factoring: 3 x 25 x 4 x 6 = 3 x 100 x 6 or 3x6 x 100 = 1800 3/4 of 24 = 3 x 6 dollars = 1800 cents

#MathStratChat 18 is 24% of what? Setting up the proportion: 24/100 = 18/w 24/100 ÷ 4/4 = 6/25 so 6/25 x 3/3 = 18/75 thus 18 is 24% of 75

#MathStratChat I guess I see the proportion built: 32/100 = 16/x. This means 'x' must be half of 100 since 16 is half of 32.

#MathStratChat Pam Harris 8% = 8/100 = 4/50 4/50 x 9/9 = 36/450 so 36 is 8% of 450

#advocacy4aging Advocacy for Aging BC I love seeing caring intelligence rewarded

#MathStratChat Pam Harris For subtraction, I really like shifting equally. Here I'd do two moves to make it simpler. 7 less and 500 more: 6015 – 3507 = 6008 – 3500 = 6508 – 4000 = 2508

Longer lives lead to breakthroughs in healthcare and well-being. Longer lifespans foster connections between generations. We need to celebrate longer lives and ensure access to quality healthcare, education, and opportunities for all, regardless of age. #StopAgeism

Shades of David Marain , I found myself on New Year's Day, observing the intersecting shadow lunes that form on my Metamucil bottle by the various overhead pot lights.

James Tanton Wayne, can you see the flaw in my reasoning. I agree with the first 4 being F(2n), but n=5? 1x1x1x1x1 one way; 1x1x1x2 four ways; 1x1x3 x3; 1x4 x2; 2x2x1 x3; 2x3 x2; 4x1 x2; 5 1+8+9+8+12+12+8+5 = 63

There are essentially just two ways to write 1/2 as a sum of two basic fractions, and just two to write 1/3 this way. a) How many ways to so write 1/5 and 1/7? b) How many ways to so write 1/4 and 1/6?
