Number Sense and Operations
Learning Standards 4.N.11
Know multiplication facts through
12 x 12 and related division facts.
Use these facts to solve related
multiplication problem and compute
related problems.
Practice Problems
Lattice Multiplication
•   Create an array.
•   Draw in diagonal lines (dotted – like lattice)
•   Put the first factor on top of the first row (above
the top two boxes)
•   Put the next factor to the right of the right hand
column.
•   Multiply each column by each row.
•   Write the products in each box.
•   The tens digits go above the dotted line, the ones
digits go below it.
•   Add the numbers within the lattice to find the
sum.
•   Each diagonal line represents the place values.

Beach Ball Mathematics
MA Mathematics Curriculum
Number Sense and Operations
Learning Standards 4.N.11
Know multiplication facts through 12
x 12 and related division facts. Use
these facts to solve related
multiplication problem and compute
related problems.
Word problem explanation/examples
Students will create their own word
problem with a picture for our bulletin
board.
Launch
• Use the beach ball to get
multiplication facts.
• Split the class in half and
have the students toss the
ball to and from their team to
warm up and remember their
facts.
Bulletin Board
• Do three examples then have
the students work in pairs to
do some also
• Put Multiplication word
problems on the board with
pictures of the sea creatures
• They can draw pictures to go
on the bulletin board.
2.Identify the information you
need to solve the problem.
3.Draw a picture or diagram if
necessary.
4.Use keywords to decide which
operations to use.
12 Students from the Salisbury Elementary
School went to the beach on
Saturday. Each student went on 10
rides. What was the total number of rides
that the students went on?

The bus ride to York Beach in Maine took
30 minutes. If the bus went to the beach
and back 2 days in a row, how many
minutes were the students on the bus?

On Tuesday, Jason found 12 crabs
at Hampton Beach. He found the same
amount of crabs on Thursday and
Friday. How many crabs did he find all
together?
If one starfish has 5 points on it, how many
points would 11 starfish have? _________

Jasper the jellyfish has 5 legs. If 9 more
jellyfish joined him, how many legs would
there be in all? ________

This crab has 2 claws and 6 legs. How many
claws would 8 crabs have? ________
How many legs? _________

Oliver the Octopus has 8 legs. How many
legs would 7 octopus have? ________

This lobster has 2 claws and 8 legs. How
many claws would 9 lobsters have? ________
How many legs? _________

If a beach ball has 5 colors on it, how many
colors would12 balls have? ___________
Mnemonic Songs
Use the memory power of music to help learn basic
mathematical processes. Here is an example of a
Multiplication Rap that I created to help students
remember their multiplication tables.

It’s time to learn our multiplication facts
If you follow along and step in my tracks
You’ll understand how to multiply
If you concentrate and really try
Now you can do it wrong or you can do it right
If you do it wrong, you’ll be here all night
Multiplication Tables Rap

1x1=1
Let’s go to the beach and have some fun
1x2=2
It sounds like something fun to do
1 x 3= 3
There’s no other place I’d rather be
1x4=4
Lot’s of creatures on the ocean floor
1x5=5
Walk in the water or take a dive
1x6=6
Can you do any diving tricks?
1x7=7
The beach is like a piece of heaven
1x8=8
Fried dough from the beach is always great
1x9=9
If you use sunscreen you’ll be just fine
1 x 10 = 10
I hope we get to go again
1 x 11 = 11
Let’s build a sand castle up to heaven
1 x 12 = 12
You can swim all by yourself!
Connections to
Curriculum Frameworks
• 4.N.9 - Select, use, and explain the commutative,
associative, and identity properties of operations
on whole numbers in problem situations
