Math
In math, we are working on
multiplication and division. A study
guide for this unit was sent home on
December 15th. Please practice
multiplication facts at home on a
regular basis. We will learn about the
multiplication tables in the following
order: 2, 5, 3, 4, 9, 6, 8, 7. We will also
learn to multiply a 2-digit number by a
one-digit number, such as 15 x 3 = 45.
A page of multiplication strategies is
attached to this newsletter.
Science
In science, we are beginning a
unit about animals. A study guide for
this unit is attached to this newsletter.

Strategies by table—2’s through 5’s
2’s tables:
1. Count by 2’s: 2 4 6 8 10 12 14 16 18 20
2. Use doubles facts in addition.
Example: 2 x 7 = _____ Find the answer to 7 + 7.
3’s tables:
1. Count by 3’s:
3
12
21
30
6
15
24
9
18
27
Try to remember the numbers in “chunks”:
Three 1-digit numbers: 3 6 9
Three numbers with 1 in the tens place: 12 15 18
Three numbers with 2 in the tens place: 21 24 27
2. Do the doubles addition fact (as you would for the 2s tables), then add that number
to it. Multiplying by 3 is doing a “triple”.
Example: To find 3 x 6, add 6 + 6, then add 6 to that
sum.
6 + 6 = 12, 12 + 6 = 18 or 6 + 6 + 6 = 18
3 x 6 = 18
4’s tables:
1. Use what you know about the 2’s tables, then double the answer.
Example:
4 x 7 = ________
Think “What is 2 x 7?”, then double that answer.
2 x 7 = 14, and 14 + 14 = 28, so 4 x 7 = 28.

5’s tables:
1. Count by 5’s: 5 10 15 20 25 30 35 40 45 50
2. The pattern in the ones place is 0 5 0 5 0 5.
3. When you multiply an even number by 5, the product is an even number (a product
that ends with 0).
Example: 4 x 5 = 20
4. When you multiply an odd number by 5, the product is an odd number (a product
that ends with 5).
Example: 7 x 5 = 35
