the digits!
We can ask two questions about a digit.
387
What is the place of the 8?
What is the value of the 8?
We can ask two questions about a digit.
876
What is the place of the 8?
What is the value of the 8?
We can ask two questions about a digit.
198
What is the place of the 8?
What is the value of the 8?
We can ask two questions about a digit.
75
What is the place of the 7?
What is the value of the 7?
We can ask two questions about a digit.
234
What is the place of the 2?
What is the value of the 2?
Which of these numbers has the greatest
amount of tens?
546
829
Which of these numbers has the greatest
amount of ones?
253
172
In which number does the 5 have the greatest
value?
546
953
In which number does the 2 have the greatest
value?

Lesson 46
SWBAT write numbers using
clues.
Today we are going to solve number puzzles. In
order to do it, we need to know some important
vocabulary.
• Sum
• Difference
• Even
• Odd
Write clues that would help someone write
the number: 349.
There is a 3 in the hundreds place.
There is a 4 in the tens place.
There is a 9 in the ones place.
I have a number with 3 hundreds place and 2 ones
place. There are no other values. What is my
number?
Lesson 47
SWBAT write three digit
numbers in many ways.
How can we model the number: 236?
There is one
easy model!
But we
want more!
How can we model the number: 236?
The last
step is to
describe
what we
see in
words!
Draw 3 models for 450.
Describe each model in words.
Draw 3 models for 641.
Describe each model in words.
Draw 3 models for 730.
Describe each model in words.
Draw 3 models for 329.
Describe each model in words.
