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?

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.

Order from smallest to largest:

Use each of the numbers 4, 40, and 4000 once to complete the sentences.

Without computing, decide whether the value of each expression is much smaller than 1, close to 1, or much greater than 1.
