Multiples


Put another row of 3 pegs underneath the blue pegs and record the new number. Place further rows of 3 pegs and record the numbers each time.


1 row of 3 = 1 × 3 = 3 2 rows of 3 = 2 × 3 =


Keep going.


All of these multiplications have the number 3 in them. We call the answers to these multiples of 3.


This time, use the squares in your copy to draw and record some of the multiples of 5. In your own words, say what you think a multiple is: A multiple is


. Your teacher can judge to see whose explanation is best. (There might even be a prize!)


What are the first 5 multiples of 4? 1 × 4 = 2 × 4 = 3 × 4 = 4 × 4 = 5 × 4 =


The answers to these multiplications will be the first 5 multiples of 4. Write them out as a list.


Now write the next 5 multiples of 4 without doing the multiplication.
