Week Ten Notes (Nov 7 - Nov 10).
Zac and I were recovering from COVID so this week was slower and quieter.
Subtraction Secrets #10
with a handful of pinecones
after I read a poem version of "The Fox and the Grapes," Zac went running off to his bedroom and proudly came back with volume A of his encyclopedia
A is for Aesop
sketching Autumn leaves
and looking through our Prismacolors to find the perfect color
Autumn brings all kinds of beautiful colors!
we decide to set up a "Track Trap" to try to capture some animal footprints
for best results, we set up two locations
we couldn't really tell if we captured any tracks
so they decided on a new setup, a cookie sheet of flour
which has been carefully smoothed out
Addition Adventures #4
with the Mortensen material
we find the missing addend in this way:
"14 is having a party and 5 wants to come.
Who does he need to bring with him?"
"17 is having a party and 9 wants to come.
Who does he need to bring with him?"
then the children choose the piece which, when added to 9, will be the same length as 17
Riddle: Why shouldn’t you tell secrets in the garden?
on Wednesday morning the children rush to the Track Trap
and we find footprints!
we continue the process of sketching Autumn leaves
two new leaves today... ginkgo and Japanese maple
all of our math is differentiated... here's a first grader's lesson
and an eighth grader's lesson
from NOAA's "Data in the Classroom" program
in Circle Time the Pterodactyls practice skip counting by 5s up to and back down from 100
I set up the first Place Value lesson
which is a trail of 100 green gems, 10 blue organza bags, and 1 red basket
in Montessori,
green = units place
blue = tens place
red = hundreds place
at the end of the trail the children will find the hundredth gem, which will go into the tenth bag, which will go into the red basket and thus show 100
they love walking the trail and counting the gems one by one
each set of ten gems is carefully placed into a blue bag
the blue bags begin to accumulate so friends help with the carrying
9 bags of 10 gems = 90
100!
in Science Club, we try to invent a new thermometer
(which does not work)
first we test to see how long it takes water to wick its way to the bottom edge of a coffee filter
and then we try four different temperatures of water (indicated by different colors) to see if hot water moves measurably faster and cold water moves measurably slower
it's hard to find the Layers of the Earth and the Layers of the Atmosphere presented in the same scale...
so we create a diagram of our own
I present a follow-up lesson on Place Value to the Pterodactyls where I show them how to represent numbers with the Montessori Golden Bead Material
the numbers that we choose are from the Dr. Seuss story
