I love number lines:)
Love this math discussion prompt. Great for kids!
I think many would say #4 is "no"
They think fractions are only part of a whole. Not ever more than a whole.
Many think fractions are one whole number over another whole number
I asked my 5th grade students to think of numbers between 0 and 1. They had no idea that there were any numbers between 0 and 1.
The IES document is a must read for folks. Add it to you quarantine reading list... if you haven't already studied it.
Great point about starting number line work with whole numbers
bar models so important to build up to this
Lucy - I agree!
Dee, I this links with your skip counting from last week. Math... it is all interconnected.
counting by knowing the size of your units
Connecting different models is very important
Excellent conversation within the Zoom session. Love hearing your voice. This will make the video vibrant. Thanks everyone!
Draw the line in the shape to make equal sized parts
I hadn't even noticed that!
I want to ask this student why they eliminated B. What were they thinking?
I think the 1/6 is labeling the space in the line above
Labelled the number line and made sure that 0 - 1 made the whole
I also want to know why they drew the line above the number line going from 0 to 1. What was the student thinking and what does that represent to the student? Wondering what the student would do if the problem was greater than 1
nested numbers within fractions
Thank you Amy for hosting a FB watch party.
Changed the unit siuze
It wasn't a numerical computation
Beautiful way to visualize equivalence. Conceptual understanding. It is important for students to physically do this students to see the mathematics.
I also find paper folding for this perception very powerful. Folding a fourths into 12ths will also help them see that
Using fraction bars, too
I use them in my classroom
These lessons have a lot of great prompts
Once you develop a strong understanding of equivalence there is even not any need to teach any method for addition and subtraction. Kids will easily see needs for creating same-size units
Those prompts would make great number talks!
i liked the reveal part that goes a doing with the activity
Would love a session on how to use JamBoard!
there has been some conversation about number lines in primary. Can we discuss your thoughts after the session?
I love this!
I like to learn how to use Jamboard better
it’s amazing how they can check work
Yes need a JamBoard session!
Jamboard is amazing! Tons of ways to use it with kids!
KNP is a treasure chest of materials for teachers.
Brian Bushart posted some of these on his website yesterday.
I saw his on Twitter
Another wonderful session! Thank you!
Thank you, Dee!
Thank you Dee!
Thank you Dee!
Thanks so much!!
Thank you, Dee!
Thanks Dee! Awesome!
Thank you so much Dee!! Wonderful activities and resources!
Thank you!! This will be great to share with my mentee teachers!! They teach the lower groups in 4th! Can help build foundation to be successful in 4th!!!
Thanks for another great session!
yes! Number talks require VERY little materials
