Dear Parent or Guardian:
Your child is currently learning to use fact families. Here is your
chance to help your child practice this important skill.
In this PAL Packet you will find a short activity for you and your
child to do. Please do the activity and The Back Page this evening.
Then sign your name on The Back Page and have your child return it

Remember, parents are a child’s first teacher. Thank you for your
time and energy in making learning fun and exciting for your child.

FACT FAMILIES
Parent Pointer —
Fact families show the relationships between mathematical operations.
This activity involves the use of fact families to show the relationship
between addition and subtraction. Fact families are used in upper
grades to show the relationship between multiplication and division.
Fact families are very useful in real life. In math, they are used to
check equations. Accountants and bankers use them in their daily
financial transactions.
Math in the Home, on the Go, and for the Fun of It —
DIRECTIONS: With your parent or guardian, read the What is a Fact
Family? page. Then do the activity on the It’s a Fact—You Can Make a
Fact Family! pages to find a fact family using a set of 3 numbers. Some
numbers may be large, but you can do it; it’s a FACT!
Talk about It —
After you have finished the activity, turn to The Back Page to show
what you know.
Now go have some fun with the activity! (

What is a Fact Family?
Fact families are number sentences that relate arithmetic operations,
such as addition and subtraction. For example:
+
8 + 3 = 11
+
3 + 8 = 11
11 − 3 = 8
11 − 8 = 3
All 3 numbers in each number sentence are the same. Each fact family
has two addition and two subtraction number sentences.
This fact family is:
3 + 8 = 11
8 + 3 = 11

11 − 3 = 8
11 − 8 = 3

It’s a Fact—You Can Make a Fact Family!
Needed: scissors and a pencil
Look at the triangles below. The first one shows the numbers 3, 9, and
12, each in a different corner. The second one shows the reverse side
of the triangle showing the addition and subtraction fact family for
the three numbers. Look at the triangles on the next page. There is a
number in each corner of the triangles. You are going to create fact
families using the three numbers on the triangle you choose just as in
the example below. Remember, each fact family has two addition and
two subtraction number sentences.
3
12
Front
9
3 + 9 = 12
9 + 3 = 12
12 − 3 = 9
12 −Back
9 = 3
Directions:
* Cut out all the triangles on the next page.
* Place the triangles upside down on a table.
* Have your parent or guardian choose a triangle.
* Have your parent or guardian use the three numbers on the triangle
chosen to write all four number sentences in that fact family on the
back of the triangle.
* Now it’s your turn to choose a triangle and write the number
sentences.
* You are finished when number sentences have been written for the
numbers on all the triangles.
