Sometimes we have to subtract to solve an addition problem.

What is the missing number?

18 + ___ = 26

Let's go over the steps with Mr. Jeff and solve some equations!!

First, we think about the numbers in the addition problem.

This causes us to notice that our equation has two parts and a whole. (part + part = whole)

Only one of the parts is missing!

Next, we change the equation so that we can find the missing part. We start with the whole 26 and take part 18 away. 

26 - 18=_____ 

26

-18

---------

Last, we can subtract to solve the addition problem.

1. Circle the ones

2. More on top, no need to stop. More on the floor, go next door and get 10 more.

Let's ask: do we need to regroup?

3. We are going to catch 8 in our hand and count up to 16. Then we stop!

4. The missing part will be on our fingers:)

Let's do it together!!

 Raise your hand if you know the answer!

 5. Check your subtraction with additon to see if it's correct.

Whole - part = part

so

part + part = whole

Our part + part did equal our whole!!

You guys are so smart.

Thank you Families!!

Families you have outdone yourselves again. Valentine's Day is so sweet and special thanks to your creativity and kind hearts!!

What is the cause?

 What causes the Moose to do the things he does in the Story "If you give a Moose a Muffin"

 Mrs. Sas helps us to understand that in this story the cause and effects make a cycle.



We worked in groups of four to put the pictures of

cause and effect into a circuit diagram,

 After we finished meeting our objective, we got to taste some muffins and graph which we liked best, chocolate, raspberry or cinnamon.

Our class had all girls like Chocolate and some boys like cinnamon. Thanks Mrs. Sas we love you!!!
