What is the value of the 3? 30
If the 3 were ten times greater, what place would it be in and what would it's value be? 30 x 10 = 300 -- hundreds place

3 groups of 14. Break the 14 in expanded form 10+4. Multiply the 3 times the 10 and the 4. Add the products.
3 X 14 (3 x10) +(3X4) =
30 + 12 = 42
6 x 23 (6x20) + (6x3)
120 + 18 = 138
7 x 132 (7x100) + (7 x 30) + (7x2)
700 + 210 + 14 = 924
3 X 14 (3 x10) +(3X4) =
30 + 12 = 42
6 x 23 (6x20) + (6x3)
120 + 18 = 138
7 x 132 (7x100) + (7 x 30) + (7x2)
700 + 210 + 14 = 924

Ask? 6 X ? = close to 254
Look at hash tag. -- Nothing lands close to 254.
Base ten hash tag (multiply by 10) 60| 120| 180
240| 300| 360
420|480|540
Look at hash tag. Is some thing close to 254?
240 is close to 254.
Count how many 10s there are ( 240 is 4 tens (40) of six
X________
6|254 |

How many groups of six are are close to 14?
Twelve is closest to 14, so there are 2 groups of 6.
Put 2 on top of the array and multiply 6 x2 = 12
X________

14- 12 = 2
2 is less than 6, so the remainder is 2.
Add 40 + 2 to find the quotient.

Square numbers make perfect squares.
4x4, 3x3, 2x2, ......
Multiple means to skip count by the number.
4, 8, 12, 16 are all multiples of 4.
Factors = Numbers multiplied together to get the product.
Multiple = skip counting
