RULES OF THE GAME
 The class is divided into two teams.
 First, second, third bases, and home plate will be designated in the
classroom.
 When a question is asked, EVERYONE responds on their white board.
 Students on the batting team will get the opportunity to respond
publicly on their white board (that is, “bat”) , one at a time, to advance
around the bases. A correct answer is a single and will move all players
one base.
 An incorrect answer is an OUT for the batting team.
 The batting teams will switch after THREE OUTS or after everyone has
batted – whichever comes first.
Miguel hit 15 home runs this season.
Sammy hit 3 times that many. Which

b) 3 x h = 15
c) 3 + 15 = h
d) 3 x 15 = h
A golden retriever’s tail is 12 inches long. A
monkey’s tail is 4 times that length. Which
equation shows how to find out how long a
monkey’s tail is? (The letter m stands for the

SOLVE THE STORY PROBLEM USING
NUMBERS, PICTURES, OR WORDS.
Each bag of cat treats costs $3. Sara
bought four bags. How much money did
Sara spend on cat treats? Write a
multiplication equation.
4 x 3 = $12 or 3 x 4 = $12
SOLVE THE STORY PROBLEM USING
NUMBERS, PICTURES, OR WORDS.
5 goldfish cost a total of $10. How
much does each goldfish cost? Write an
equation to show how you solved.
Examples:
5 x n = 10 n = $2
10 ÷ 5 = $2
MRS. HEITLAND SPILLED COFFEE ON HER
PAPER, MAKING IT HARD TO SEE. HOW
MANY DOTS ARE THERE? SHOW YOUR
WORK.
For example:
6 x 5 = 30
How many
mailboxes are
there? Include
the hidden
ones! Show
your work.

6 x 4 = 24
USE THE PICTURES YOUR TEACHER GIVES
YOU TO SOLVE THIS PROBLEM. THE
TRIGGERFISH IS 10 INCHES LONG. HOW
LONG IS THE SAND TIGER SHARK?
About 40 inches long
Explain how you can use 2 x 6 to
figure out the answer to 4 x 6.
Evan says he figured out the answer to 5 x 8
this way:
I knew what 10 x 8 was, so I just found half
of that answer to get 5 x 8.
Do you agree with Evan’s reasoning? Why or
why not?
