I can add large numbers. (Also, I can rewrite numbers
vertically to solve.)
Solve:
a) 423 + 164 = ______
b) 648 + 226 = ______
c) 752 + 171 = ______
d) 285 + 396 = ______
e) 876 + 749 = ______
I can add large numbers. (Also, I can rewrite numbers
vertically to solve.)YOU MUST WRITE THESE VERTICALLY!
Solve:
a) 423 + 164 = 587
b) 648 + 226 = 874
c) 752 + 171 = 923
d) 285 + 396 = 681
e) 876 + 749 = 1,625

I can write and solve related word problems.
Mary had 23 lambs. She got 20 more. How many lambs does Mary have now?
_____ + _____ = ______ lambs
Now, write a related subtraction problem, using all three of the numbers from the “Mary” problem.
Get your answer to the problem without calculating!
I can write and solve related word problems.
Mary had 23 lambs. She got 20 more. How many lambs does Mary have now?
23 + 20 = 43 lambs
Now, write a related subtraction problem:
Mary had 43 lambs. She gave 23 to her friend Jenny. How many lambs does Mary have now?
43 – 23 = 20 lambs (I didn’t need to calculate because I could just look at the related problem.)
I can write and solve related word problems. (Another example.)
I made 620 chocolate chip cookies. I sold 435 cookies. How many cookies do I have left?
620 – 435 = ________ cookiesNow, write a related addition problem,
using all three of the numbers from the “cookie” problem.
Get your answer to the problem without calculating!
I can write and solve related word problems. (Another example.)
I made 620 chocolate chip cookies. I sold 435 cookies. How many cookies do I have left?
620 – 435 = 185 cookies
Now, write a related addition problem:
I bought 185 cookies. Then I bought 435 more cookies. How many cookies do I have now?
185 + 435 = 620 cookies (I didn’t need to calculate because I just looked up at the related problem.)
I can find the cost of two or more items.
I bought a pair of soft socks for $3.55 and a shirt for $9.50.
How much do the two items cost altogether?
If I pay with a $20 bill, how much change will I get back? (How much money will I get back?)
I can find the cost of two or more items.
I bought a pair of soft socks for $3.55 and a shirt for $9.50.
How much do the two items cost altogether? $3.55 + $9.50 = $13.05
If I pay with a $20 bill, how much change will I get back? (How much money will I get back?)
$20.00 - $13.05 = $6.95 back
