3 Digit Addition
Find the sum:
710 + 195 =
710 + 195 = 905
Find the sum:
1,082 + 4,709 =
1,082 + 4,709 = 5,791
Round the following number to the nearest tens place:
673
Since 7 is in the tens place, we look at the ones place. 3 is "4 or below" so we KEEP the 7 low.
673 rounds to 670
Which addition property is shown from the following equation:
0 + 583 = 583
The IDENTITY PROPERTY says any number plus zero equals that number, so
0 + 583 = 583
shows the Identity Property
Tommy played video games for 1 hour on Saturday and 48 minutes on Sunday. How many total minutes did Tommy play video games over the weekend?
(Hint: 1 hour = 60 minutes)
Since 1 hour equals 60 minutes,
60 + 48 = 108
So, Tommy played video games for 108 minutes.
Find the sum:
583 + 274 =
583 + 274 = 857
Find the sum:
3,653 + 298 =
3,653 + 298 = 3,951
Round the following number to the nearest tens place:
368
Since 6 is in the tens place, we look at the ones place. 8 is "5 and above" so we give the tens place a shove.
368 rounds up to 370
Which addition property is shown from the following equations:
135 + 200 = 335
200 + 135 = 335
The COMMUTATIVE PROPERTY says that the addends can be added in any order and still equal the same sum, so
135 + 200 = 335 and 200 + 135 = 335
shows the Commutative Property
Carly ate 1,232 grains of rice. Riley ate 975 grains of rice. How many grains of rice did they eat in all?
1,232 + 975 = 2,107
So Carly and Riley ate a total of 2,107 grains of rice.
Find the sum:
$366 + $729 =
$366 + $729 = $1,095
Find the sum:
$1,245 + $3,642 =
$1,245 + $3,642 = $4,887
Round the following number to the nearest hundreds place:
459
Since 4 is in the hundreds place, we look at the tens place. 5 is "5 and above" so we give the hundreds place a shove.
459 rounds up to 500
Which addition property is shown from the following equation:
(2 + 9) + 4 = 15
2 + (9 + 4) = 15
The ASSOCIATIVE PROPERTY says that addends can be grouped in any order and will equal the same sum, so
(2 + 9) + 4 = 15 and 2 + (9 + 4) = 15
shows the Associative Property
Woodlands Elementary had a bake sale. They sold 2 kinds of cookies, chocolate chip and snickerdoodles. If they sold 215 chocolate chip cookies and 145 snickerdoodles, how many cookies did they sell in all?
After solving, round your number to the nearest hundreds place.
215 + 145 = 360
Woodlands Elementary sold 360 cookies in all.
Since 3 is in the hundreds place, we look at the tens place. 6 is "5 and above" so we give the hundreds place a shove.
360 rounds up to 400
Find the sum:
$999 + $404 =
$999 + $404 = $1,403
Find the sum:
$6,048 + $3,895 =
$6,048 + $3,895 = $9,943
Round the following number to the nearest hundreds place:
7,195
Since 1 is in the hundreds place, we look at the tens place. 9 is "5 and above" so we give the hundreds place a shove.
7,195 rounds up to 7,200
Write an equation that shows the Identity Property of Addition.
Example:
2,061 + 0 = 2,061
Katie ran 1 mile. Allison ran 3,650 feet. How many feet did they run in all?
(Hint: there are 5,280 feet in 1 mile)
5,280 + 3,650 = 8,930
So Katie and Allison ran 8,930 feet in all.
Find the sum:
$888 + $777 =
$888 + $777 = $1,665
Find the sum:
$7,426 + $ 7,537 =
$7,426 + $7,537 = $14,963
Round the following number to the nearest hundreds place:
$4,928
Since 9 is in the hundreds place, we look at the tens place. 2 is "4 or below" so we KEEP the 9 low.
$4,920 rounds to $4,900
Write two equations that show the Commutative Property of Addition.
Example:
75 + 10 = 85 and 10 + 75 = 85
Walmart sold $2,633 worth of turkeys for Thanksgiving. Safeway sold $2,495 worth of turkeys for Thanksgiving. How much money did both store make together from selling turkeys?
$2,633 + $2,495 = $5,128
So together, the two stores made $5,128 from selling turkeys.
