Chapter 1  Unlock the World of Adding
Adding + Adding = Understanding Adding
Adding is the joining of two groups and can be shown in an adding
sentence that uses the + sign and the = sign to show the answer. The big
idea that we focus on is that the biggest number in an adding sentence
is at the end.
Making Numbers Using 10
In order
to be successful at adding and subtracting, numbers have to be your
child's best friend!! Children need to know all about numbers and the
world that they live in. In order to understand that 4+4=8, the child
first needs to see that 8 can be broken up into 2 groups of 4 and 4
more. A ten frame can be used as a tool for kids to see these
combinations, especially if different color counters are used. Bigger
numbers also can be represented on the ten frame by adding the extra
underneath.
When
adding counters to a tenframe, fill the top row first; then add
counters to the second row so the relationship to 5 and 10 becomes
apparent.
Example "12" on a ten frame Say, "10 and 2 more is 12"
We
also learn in this chapter that there are a lot of ways to add. Are you
ready for this, because here come some ways to help your child add like
a pro!
1. Draw pictures of the groups.
This is where you can see the budding artists start to come out. While
we love ourselves some good artwork, make sure that the math is the
focus. We make quick pictures in class and save the masterpieces for our
other projects. Draw one group of the sentence and then the other and
count how many in all.
5 + 2 =
+
2. Use
objects. Grab anything small around the house and put them in groups.
From cars to dolls to raisins to chocolate chips, you can use anything
to represent the adding in math stories!!
3. All you have to do is turn it around!!
We have a
lot to do as First Graders so we need to add and move on, so if we can
find some tricks then have at it! This one shows that as long as the
numbers are the same it does not matter what order they are in because
the answer will be the same. That means...
If you know 3 + 5 = 8 then you "turn it around" and get...
5 + 3 = 8!!! That is it!! Now practice for yourself!!
4. Zero is our Hero.
If you are adding with 0 then your answer is the number you started
with. Here is the secret, you actually do not have to add!! If you see
zero you know that things will be good for you!
ACTIVITIES FOR CHAPTER ONE CONCEPTS
Here you will find some extra activities to reinforce the concepts from this chapter.
Activity 1 Number Combinations
Materials: counters (can be anything you find in the house), paper, crayons
Procedure:

Tell a simple math story such as:
There are 7 children in a room. Some are boys and some are girls. How many can be boys and how many can be girls?

Have the children show one possible solution using counters and then record the solution like this:
4 boys and 3 girls

Then the partner or parent males a different way. Go back and forth
taking turns until there are no other ways to make the number.

The child can make a book of the different numbers and ways to make
that number. You will be quite amazed at the homemade number book!!!!
