5.NBT.2
Support Videos & Extra Practice
In this standard, students are expected to multiply and divide by powers of ten.
10 = 10^1
10 x 10 = 100 = 10^2
10 x 10 x 10 = 1,000 = 10^3
Example:
Method 1: 2.5 x 10^3= 2.5 x 1000 = 2,500
Method 2:
2.5 x 10^3=
2.5 x 10 = 25
25 x 10 =250
250 x 10 = 2,500
Example:
Method 1: 350 ÷ 10^3 = 350 ÷ 1000 = 0.350 = 0.35
Method 2:
350 ÷ 10^3 =
350 ÷ 10 = 35
35 ÷ 10 = 3.5
3.5 ÷ 10 = 0.35
