Estimating Decimals with Multiplication

This is a blog of today's notes and homework.

What is the total when estimating?

1.69 x5= Tax is included.

Younger sister says it only costs 5 bucks.
Older brother says it only costs 10 bucks.

What are they thinking, how are they estimating?

Younger sister is thinking Under estimating, just 1.00x5= $5.00

Older brother is thinking Over estimating, 2.00x5= $10.00

Where do the decimals go?
2.2 x 1.8= 3960

Where do the decimals go here?

3.9 x 5.8= 22620
Is $9.00 enough and prove it.


2.57 x 0.45= 118220


Pronghorn: 58kg Dall's: 1.5 times as much as a pronghorn.
How much does Dall's weigh?
Approximate: 90kg. 60x1=60 kg.
90 kg. (In between the two weights.)
60x2=120 kg.
Exactly: 87kg.


Homework is:

46x2.5 = 64x4.5 = First estimate then calculate.


Here is a video for multiplying decimals. If you click multiplying decimals it will take you to a link that explains the multiplying of decimals. Good Luck and I hope it isn't hard to understand.






Mr.Isfeld will be collecting number of the day tomorrow.
