What about this problem…
Leslie went to her favorite place to
eat. When she got there she noticed
2 cars in the parking lot.

Leslie went to her favorite place to

Then 8 more cars pulled

Let’s talk about it!
What is your answer
and how did you find
it?
Now how many cars are
in the parking lot?
Now you will need……
• A pencil
• 12 snapcubes
• A building map
• A 1-10 spinner
Let’s take a look at the building map
How do you think we could use numbers
with it?
Today we are going to use it to record how some
numbers are connected.
Let’s do one together!
First we need a number.
I’ll spin the
spinner to get a
number.

Now let’s build a model with 2 snap
cubes.

Look at the top of the building.
What is it
telling us to
do?

So we need to add 1 more cube to our
model.
2
Write a 3 in the window next to
the 2.

Try and finish the +1 building now.
BUT REMEMBER…
Once you spin a
number and put it in
a window - you
CAN’T use it again
on that side of the
building.

When you finish the +1
building, try the +2
building.
If you finish early….
Choose one:
 Use more snap cubes and try to find
more numbers that are connected by +1
or +2. Write down the connections in your
journal.

Play an addition folder game.
