Count the stars, how many do you see?

Let us count together the circles as they appear!! How many are there?

4 or you can write it as four

16 or SIXTEEN

Now let us try counting higher!!

How about we count the ice cream flavors that Ben and Jerry's offers!!!flavors

Now try this on your own…

How Many fingers do you have?

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

Grouping

GROUPS OF 2

+

=

+

+

=

1 + 1 = 2

2 + 2 + 2 = 6

Groups of 5

+

+

=

5 + 5 + 5 = 15

Groups of 10

= 1 group of 10

=

10 + 10 + 10 + 10 = 40

Try these simple addition problems and

use the tally marks underneath each problem for help!

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?

1 + 4 = 5

+

=

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?

Write an addition sentence that fits the story:

2+ 1= 3

+

=

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?

1+2+4= 7

Post Test

Can you count to 99? Try it starting with 0….FEEDBACK

2. How many shapes are in this picture? ShapesFEEDBACK

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

a. 1+1=

b. 3+7=

c. 4+1=

6. John goes to the store and buys two N.C. State t-shirts , one N.C. State hat and 3 N.C. State key chains for his friends. How many items did he buy? FEEDBACK

FEED BACKfor right and wrong answers

COUNTING

• Right- Refer to the table

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 IIIIIIIIII

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!!

• 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!)

Post Test

FEED BACKFor right and wrong answers
• Right- The 3 is in the ten’s place and the 7 is in the ones place

Picture- Ten’s Place Ones Place

Wrong- IF you did not understand this then refer to above or go the e-manipulative site and play with the blocks until you understand place value! E-manipulative

• Right-

a.1+1=2

b. 3+7=10

c. 4+1= 5

Wrong- Draw Pictures to help you understand! Or use the number line!

• Right- 2 shirts+ 1 hat+ 3 key chains= 6 Items

Wrong- How about we draw a picture to help us out!!!

OR USE TALLY MARKS….

II + I + III = IIIII I
