Try out at least 2 of the In the Classroom activities in chapter 8-there are 5 throughout the chapter. (I think 8-5 is really challenging, I’d love to have someone explain question 5 on In the Classroom 8-5.) Tell us which In the Classrooms you completed and share what you discovered aboutPlace Value  as you completed the activities.

, click on Numbers and Operations prek-2 and try out Base Blocks, Base Blocks Addition, Base Blocks Subtraction, Hundreds Chart. Share-What was reinforced? What ideas did I connect with? What questions do I have?

3. Select one of the four characteristics of our number system and make a visual representation of it. OR Show how 201 and 120 would be represented with three different place-value models (concrete physical models, semiconcrete organizational models, symbolic representational models). This could be done electronically using Word Art, clip  art, in a ppt slide, hand drawn and a photo taken and uploaded, models made with objects from home and then a photo taken and uploaded or however your genius allows-as long as you can share it with us.

And you

How much volume do you think 100 average size peas would take up?
They would occupy approximately one cubic inch.
(Although personally, I think you may need to mush them together to make them fit)

How much volume do you think a million peas would occupy?

Approximately the volume of an average house (do not try this at home)

Yes an entire house from the basement to the attic full of peas

About 1000 houses (the size of a medium size town.
But are we even close to a mole of peas?
Oh no – not even close!

That is a lot of peas!!!!!!!!!!!!!!!!
Enough to fill all the buildings in Mississauga!

NO
Not yet

Well that would be enough peas to cover the entire province of Ontario with peas nearly 4 feet deep!!!!!!!!!!!!!!!!!!!!!!!!!!!!
But still not even close to a mole of peas
I am sorry I could not find a photo of Ontario covered in 4 feet of peas

Yes this is a real number!
This would be enough peas to cover all the continents of the world with peas 4 feet deep. Imagine North America, Africa, South America, Europe, Australia, Asia, all covered with 4 feet of peas!!!!!!!
Still not close to a mole of peas

Imagine 250 planets the size of the Earth completely covered with 4 feet of peas.
This would be a mole of peas
Give or take a few peas of course

How many peas would I have if they were the same as the number of atoms in my body???????????????????????????
A cotillion peas (1 x 1027)

Would be 4 feet deep
And cover 250,000 planets the size of earth!!!!!!!!!!
Wow a mole is a really big number then.
So everything that contains a mole of atoms must be really big right????

Because atoms are very small!
