Lesson 41
SWBAT model one number in
several ways.
How can we model the number: 36?
Two models
are easy!
But we
want more!
How can we model the number: 36?
The last
step is to
describe
what we
see in
words!
Draw 3 models for 50.
Describe each model in words.
Draw 3 models for 41.
Describe each model in words.
Draw 3 models for 30.
Describe each model in words.
Draw 3 models for 29.
Describe each model in words.
Lesson 42
SWBAT make a hundred in many
different ways.
Today we’re going to model 100!
Let’s start by thinking
of numbers that almost
make 100.
Now, let’s try to make 100 by counting by 1s.
Fill in the 100s chart on your guided practice.
Today’s IP is different than usual!
Your job is to make 100 using one of the
materials at your table.
Lesson 43
SWBAT represent three digit
numbers in written, pictorial
and expanded form.
Today, instead of using unifix cubes we’re
going to use place value blocks.
Let’s try it with the number 41.
So, how can we model 123 in the quickest
way possible?
