Multiples of Ten

Were you able to determine the next three numbers in the pattern?

Discuss your response with a teacher or parent. The next numbers in the pattern should be 50, 60, and 70. If you answered correctly, you have just counted by tens, which means you should easily be able to multiply by ten.

Before you start learning more about the ten times tables, take a few minutes to review what you have learned so far. Can you complete each of the following patterns? Share you answers with a teacher or parent:

• 2, 4, 6, 8, ___, 12, ___, ___
• 5, ___, 15, 20, ___, 30, 35, ____

Were those patterns easy to complete? If not, go back and review the Related Lessons in the right-hand sidebar on multiples of two and five before moving forward. It is best to make sure you have mastered each of the sets you have already been taught before trying to learn more multiplication facts.

Were you able to complete the pattern at the beginning of the lesson? If so, you counted by tens and already know your ten times tables! To hear all of the ten times tables, listen to the song 10 Time Tables "ROCK" (SOHLkids.com):

Did you notice that the product of any number multiplied by ten ends with a zero? Finding the answer to a multiplication problem with ten is easy. Just add a zero to the end of the number being multiplied by ten! For example, the product of 10 x 3 is 30. You just add a zero after the 3. Add this tip to your foldable under the "10" flap.
