ADDITION AND SUBTRACTION CONNECTIONS 1

In math, we say that subtraction is the inverse of addition That means that they are opposites they undo each other You can subtract to double check an addition problem.

EXAMPLE: If you know that 3 + 7 = 10 then you can subtract using those same numbers to

check your thinking: 10 - 7 = 3 or 10 - 3 = 7!

DIRECTIONS: Find the missing number in the irst column and complete the addition number

sentence Then subtract to double check your thinking Write a subtraction

number sentence in the blank box to show the inverse of what you added.

then then then then then then then then

*Children do not have to write both subtraction options in their answer.

ADDITION AND SUBTRACTION CONNECTIONS 2

In math, we say that addition is the inverse of subtraction That means that they are opposites they undo each other You can add to double check any subtraction problem.

EXAMPLE: If you know that 8 - 6 = 2 then you can add using those same numbers to check

your thinking: 2 + 6 = 8 or 6 + 2 = 8!

DIRECTIONS: Find the missing number in the irst column and complete the subtraction

number sentence Then add to double check your thinking Write an addition

number sentence in the blank box to show the inverse of what you subtracted.

INVERSE ADDITION PRACTICE

The missing number in these addition problems all come at the beginning of

the number sentences Can you work backwards using the inverse operation

(subtraction) to complete each problem? Give it a try!

INVERSE SUBTRACTION PRACTICE

The missing number in these subtraction problems all come at the beginning

of the number sentences Can you work backwards using the inverse operation

(addition) to complete each problem? Give it a try!

ADDITION AND SUBTRACTION CHALLENGE:

Look carefully at these addition and subtraction problems Fill in what is missing to complete the inverse operation Can you follow the pattern?

FACT FAMILY DICE

Add together the two dice to ind the missing fact family number Fill in the fact triangle using these numbers Remember that the biggest number always sits at the top of the triangle! Then build your fact family number sentences using the blank lines

FACT FAMILY DICE # 2

Now subtract the two dice to ind the missing fact family number Fill in the fact triangle using these numbers Remember that the biggest number always sits at the top of the triangle! Then build your fact family number sentences using the blank lines.

FACT FAMILY MIX UP!

Fill in the missing numbers in the fact family house Then, ind the roof that matches the bottom of the house and draw a line to connect the two pieces.

FACT FAMILY MIX UP!

Cut out all of the roof pieces on page 1 Find the bottom of the house on page 2 that matches each roof and glue your house pieces together If a fact family house

is missing some information, make sure to ill it in yourself.

MAKING NUMBER CONNECTIONS

Complete the fact family houses below Then use the word bank at the bottom of the page

to answer the questions.

_ - _ = _ _ - _ = _

_ + _ = _ _ + _ = _ _ - _ = _ _ - _ = _

_ + _ = _ _ + _ = _

_ - _ = _ _ - _ = _

_ + _ = _ _ + _ = _ _ - _ = _ _ - _ = _

Use the words in the word bank to complete the sentences below.

1 When you add two even numbers together, the total or sum will always be _

2 When you add two odd numbers together, the total or sum will always

_ + _ = _ _ + _ = _

_ - _ = _ _ - _ = _

_ + _ = _ _ + _ = _ _ - _ = _ _ - _ = _
