Activity 1 Multiplication Tables for 2, 3, 4, and 5
jOb ective Learn the multiplication tables.
1. Textbook Instructions Activity 1 Multiplication Tables for 2, 3, 4, and 5
Tell students to write the results of skip- 1 Follow the rule and skip-count on the number line to find each
counting by 2, 3, 4, and 5 on the number line,
and then write them in the multiplication table. product. Then complete the multiplication table.
1. Guide students to distinguish between “ a Skip-count by 2s
1” and “ 10” using skip-counting.

1a. Explain why 2 1 and 2 10 yield
different answers using skip-counting. ^ 1 2 3 4 5 6 7 8 9 10
Example: 2 1 means 2 skip-counted once, 2 2 4 6 8 10 12 14 16 18 20
so it equals 2, and 2 10 means 2 skip-
counted ten times, so it is 20.

Multiplication table
There are multiple ways to express model multiplication.
skip-count
use arrays
draw a picture
This unit covers model multiplication in the order of skip-counting, arrays, and drawing pictures. These 3
methods will help students to understand the multiplication table.
