1.69 x 5 ( tax included )
Younger sibling says it only costs 5 dollars.
Older sibling says it only costs $10.
What are they thinking , how are they estimating ?
The younger sibling is under estimating. $1 x 5= $5.00 front end estimating
The older sibling is over estimating.$2 x $5= $10 rounded it . Relative size .
Is $9.00 enough, and prove it .
$1 x 5= $5.00 $9 - $5= $4.00 left .
0.69 = 0.70 x 5 = 3.5
$5 + $3.50 = $8.50
OR
$1.69 = $2.00 $2.00 x $5 = $10 0.31 = 0.30 0.30 x 5 = 1.50 $10.00 - $1.50 = $8.50
Where does the decimal go ?
2.2 x 1.8= 3960
2.2 rounded = 2
1.8 rounded = 2 x 2 = 4
4 is the near 3.960.
3.9 x 5.8= 22620
3.9 is rounded to 4
5.8 is rounded to 6 x 4 = 24
24 is close to 22.620
2.57 x 0.45= 1.18220
2.57 is rounded to 3
0.45 is rounded to 0.50 x 3 = 1.5
1.5 is the nearest to 1.18220
A pronghorn is 58 kg .
A Dall's weighs 1.5 times as much
How much does Dall's weigh ?
58 kg = 60 kg x 2= 120 kg
60 kg x 1= 60 kg
90 kg is between 120 and 60.

ReplyDeleteP.S. Thanks for posting the homework.
Nice job Allison. I liked when you made the words "front end estimating" and "rounded it. relative size ." faded and grey.
ReplyDeleteI think that you could have made the words that are likely to be the key words, coloured or linked to its definition.
ReplyDeleteI also liked when you made the words "Where does the decimal go ?" and "Homework" in colour to show that those were a new section.
ReplyDeleteI agree with Hanna. I think that you could have used a larger font. But overall it was well done.
