Let us count
together the circles
as they appear!!
How many are
there?
4 or you can
write it as
four
Now try this on your own…
How Many fingers do you have?
Count the stars, how many do you see?
16 or SIXTEEN
Now let us try counting higher!!
How about we count the ice cream flavors
that Ben and Jerry's offers!!!flavors
10 or TEN
How many?
63 or sixty-three
Place Value
The number system that we use is the Hindu-Arabic Numeration system.
This system counts in the Base of 10 and each number has an important
place value that it holds.
15
Now lets break the number 15 apart
And we will have 1 and 5.
In math the five is in the ones place and represents 5 ones
Ex: each of these blocks equals 1 so now we have 5 of them
Now we also have a 1 in the number 15 and it is in the tens place. So we have
one ten.Ex: This block represents one ten
Here is a COOL website dealing with place Value Base Blocks - NLVM

Single Digit Addition
Try these simple addition problems and
use the tally marks underneath each problem for help!
NUMBERS
1 + 1= 2
I + I = II
WORDS
One + One = Two
1 + 2= 3
I + II = III
One + Two = Three
2+3= 5
II + III = IIIII
Two + Three = Five
8
3 + 5=
III + IIIII = IIIII III
5+4=
IIIII+ IIII=
9
IIIII IIII
Number Line
Arithmetic - NLVM
Three + Five = Eight
Five + Four = Nine
Solving Word Problems
(draw pictures to help)
1. Gabriel went to a car dealership. Before talking to
the salesperson, he looked at 1 pickup truck. After
talking to a salesperson, he looked at 4 more pickup
trucks. How many pickup trucks did he look at in all?
2. Tanner went shopping for Father's Day and
bought 2 solid black shirts and 1 green striped shirt.
How many shirts did he buy in all?
1+4=

=
2+ 1= 3

Write an addition sentence that fits the story:
3. The snack bar sold 1 soda, 2 bottles of water, and
4 cups of coffee. How many beverages did the snack
bar sell in all?

2. How many shapes are in this picture? Shapes FEEDBACK
3. Can you make a group of 2, 5 and 10 on your paper using tally marks? FEEDBACK
4. In the number 37, what are the place values of the 3 and 7? Can you draw a
picture showing this using the ones and tens blocks? FEEDBACK
5. Solve… FEEDBACK

for right and wrong answers
1.
Right- Refer to the table
COUNTING
Wrong- If you messed up in your counting, writing the numbers down could help you, make a
table like the one we have used!
2.
Right- 12
Wrong- Make groups of 2 to help you organize the shapes when counting using tally marks
Ex: II II II II II II
2 4 6 8 10 12
Or you can draw them out and make part of the number table to help you count
correctly…Remember if you need help then DRAW A PICTURE!!
3.
Right- Groups of 2- II
Groups of 5- IIIII
Groups of 10- IIIII IIIII
Wrong- Most likely you got the group of 5 or/and 10 wrong. If you did then here are some
other ways to look at this…make a simple addition problem using tally's
Ex: II+III=IIIII 2+3=5
Ex: IIIII+IIIII=IIIII IIIII (break the ten’s group down into 2 sets of five!)
