 Introduction to Lattice Multiplication
 MA Mathematics Curriculum
Frameworks ~ Grades 3-4
     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
Frameworks ~ Grades 3-4
    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
  students thinking about their
  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.
• Discuss Undersea Adventure
  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.
1.Read the problem carefully.
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.
5.Show your work.
6.Check your answer.
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!
