Just joining to see your smiling face!
the first one is 1.12 per roll the second one is 1.33 per roll ...so
I am worried it's a trap bc one said regular rolls and one said big rolls.
Bounty is the better buy. I used fractions and common denominators.
8 rolls is a better buy!
eight rolls becuase its 1.12 instead of 1.33
I also look for the number of sheets or square feet to determine value
Bounty 8 rolls i meant
Bounty - I looked at how much more than $1 per roll for each package
8 rolls a better buy
I need to know how many are on each roll.
8 rolls is a better deal.
I do that too Lisa
although I am partial to the select a size option of towels!
Me too, Julie!
I did the same thing, but used 24
I did 8.99 /8= 1.12 per roll. and 7.99/6= 1.33 a roll.
That was my first way as well, Amanda.
My second way was to round to the nearest dollar: 9/8 compared to 8/6. Works for quick grocery math.
This is the worst buy.
8 rolls is still the better buy
This one is $1.50 per roll, so is worse than both the others
Rounding was the biggest obstacle for students in my Dual Credit courses. Typing their answers into the collegiate computer software meant their answers had to be rounded correctly and many of them struggled with that. That was a really good point, Kelly.
I agree with carrie
Does it always kelly?
When my daughter shops with me that is her role. To determine which size, or brand is the Best Buy.
That's great- Lisa! Good parenting!
Kids can TASTE mathematics - I love it!
the second one
4:5 - It's closer to being half orange
Yes- comparing to benchmark fractions! Harkening back to intermediate fraction work. :-)
The one with 4 parts orange, 5 parts Fresca
4 orange : 5 soda
4 to 5
sorry I lost connection
4 to 5 is orange.
The second one...it's stonger! closer to being all orange, or closer to 1 whole.
75% vs 80% so the 4/5 is orangier (that may not be a word)
I thought about it as parts to the whole. And it is a lot closer when you compare it that way
3:7 to 4:9 is 43% to 44%
4:5 is stronger-- built up to compare common numerator (orange) 12:15 as compared to 12:16.
3 of 7 parts vs 4 of 5 parts
What a treasure Kelly!
Wow! Now I am hungry and thirsty! What a treasure!
Do you want thick or thin brownies?
sorry again...keep losing connection
The volume of the required pan is 128 and the volume of your pan is 234. That is close to twice as large, so I would recommend double the recipe
Need to double it. Thinking from a cooks point of view.
I would decrease the bake time
I would double it!
Compare the area of each pan - the 8x8 is 64 and the 9 x 13 pan is 117. It's approximately double.
Thinking area....the 9 x 13 is 1.8 larger
double it, or buy a new pan..hehe
I would double
This is a life skill I missed! LOL!
Julie. I need to bake with you sometime when we can be in the same space!
My wife asked me a question about this the other day about diluting bleach for a cleaning spray, and it was 1 part per 100
I love this! Cool color mixing!
Wow - that is a great visualization!
Great job Kelly! I loved all the real world applications!
Thank you so much!!!! Awesome
thank you so much, love the interactive links
I will be trying this with my Tristan! Thanks, Kelly for the real life math! Dee- I will welcome the baking lessons!! Have a great afternoon!
Thanks so much! Great job Kelly!!!!
Wonderful! Loved it!! Interesting
Wonderful! I love the resources!
You are the best! Thank you!
Thank you for the reminder to SLOW DOWN and that LESS IS MORE.
Thanks!!! You did a great job! I miss you!!
Thank you so much! I've been enjoying these so much this week! Breaking up the NTI
Thanks for all the good info & resources!!
Thank you! I love learning about new resources
Awesome! Loved the visuals with technology and connections to real life.
