IM 6.4.1 Lesson: Size of Divisor and Size of Quotient
Find the value of each expression mentally.
Here are several types of objects. For each type of object, estimate how many are in a stack that is 5 feet high. Explain your reasoning.
Cardboard boxes
Notebooks
Bricks
Coins
A stack of books is 72 inches tall. Each book is 2 inches thick. Which expression tells us how many books are in the stack?
- A
- B
- C
- D
Explain your reasoning for the answer you chose in the previous question.
Another stack of books is 43 inches tall. Each book is -inch thick. Write an expression that represents the number of books in the stack.
Without computing, estimate the quotients in this set and order them from greatest to least by dragging the expressions.
Explain how you ordered the division expressions in this set.
Record the expressions in each set in order from the greatest value to the least.
Without computing, estimate the quotients in this set and order them from greatest to least by dragging the expressions.
Explain how you ordered the division expressions in this set.
Record the expressions in each set in order from the greatest value to the least.
Without computing, estimate the quotients and sort them into the following three groups.
Explain how you sorted each expression into one of the three groups.
Write 10 expressions of the form 12÷? in a list ordered from least to greatest.
Can you list expressions that have value near 1 without equaling 1?
How close can you get to the value 1?
