Students will play a variety of games to understand multiples and practice their multiplication skills.

Background for Teachers
Mathematics is especially useful for predictions. Multiples and other
number patterns are all about prediction. Working with number patterns
helps students develop their concept of functions in mathematics.
The very youngest children start simply by counting. Then they start
counting in multiples—twos, fives, tens, etc. These number patterns give
students a natural strategy to understand addition and multiplication.
Students start by using patterns to find sums: 2 + 2 = 4. As students get
older they start using their knowledge of patterns to find products. When
asked what 5 x 9 is, they will count by fives nine times. High school
students can use their knowledge of number patterns to start to
understand functions and other algebraic concepts.
Intended Learning Outcomes
3. Reason mathematically.
Invitation to Learn
Play a skip counting song from the math songs CD. Let children
discuss and demonstrate their favorite examples of skip counting.
Ask students how learning the skip counting songs could help them
learn their multiplication tables. Introduce the concept of multiples
and explain that it is the same as skip counting. Reinforce their
understanding of the connection between multiples and multiplication
Calculator/Skip Counting Activity
- Pass out hundreds chart and calculator for each student.
- Use your overhead calculator to demonstrate.
- Review how to skip count on a calculator (e.g., 5 + 5 = = = =, the
calculator will count by multiples).
- Do familiar multiples such as twos, fives, tens where they will be
able to easily recognize the patterns
Ask questions as students work with the calculators, such as
“What pattern do you see when______?”
............you skip count by 2s and start with 2? Why????
............you skip count by 2s and start with 1?
............you skip count by 5s and start with 3?
Skip-counting by what numbers will include 100 in the pattern?
Note: Always ask “why” to give the students a chance to
understand and verbalize their understanding of what is
happening on the calculator.
Explain that many people enjoy riddles, games, and other
activities that require the recognition of number patterns to solve.
Play using The Birthdate Game handout.
Play using the I Spy handout.
Introduce students to stories/books about detectives and mysteries. Two Minute Mysteries and Encyclopedia Brown books by Donald Sobol
work well for fourth graders.
Use the Math Songs CDs and have children learn and sing the skip
counting and multiplication table songs.
- Give students copies of the Birthdate Games and I Spy handouts
to take them home and share with their families.
- Use informal quick response activities to assess students’
understanding of multiples. For example, call out a number
pattern and then call on a student to give you the next number.
- Formal assessments such as the 100 basic multiplication and 90
basic division facts tests are one way to show progress toward
mastery of these skills. Students should be given adequate time to
complete fact test with greater emphasis on accuracy versus
speed. You can also assess student understanding of skip
counting and multiples by assigning them to write sets of
multiples (e.g., write the multiples of three from 3 to 36, etc.).
