I can write a number in expanded form.

Write 428 in expanded form.

Write 1,098 in expanded form.

I can write a number in expanded form.

Write 428 in expanded form.

400 + 20 + 8

Write 1,098 in expanded form.

1,000 + 90 + 8

I can compare whole numbers.

Write < > = to make the statement true.

428 ____ 482

1,650 ____ 650

50+ 10 ____ 60

I can compare whole numbers.

Write < > = to make the statement true.

428 < 482

1,650 > 650

50+ 10 = 60

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 subtract large numbers, but I rewrite them vertically first!

a) 976 – 451 = _____

b) 862 – 428 = _____

c) 926 – 673 = _____

d) 842 – 569 = _____

e) 700 – 432 = _____

f) 507 – 329 = _____

I can subtract large numbers, but I rewrite them vertically first!

a) 976 – 451 = 525

b) 862 – 428 = 434

c) 926 – 673 = 253

d) 842 – 569 = 273

e) 700 – 432 = 268

f) 507 – 329 = 178

I can add and subtract mentally when it makes sense to do so.

Solve mentally:

I can add and subtract mentally when it makes sense to do so.

Solve mentally:

a) 8 + 6 = 14b) 80 + 60 = 140c) 800 + 600 = 1,400d) 10 – 4 = 6e) 100 – 40 = 60f) 1000 – 400 = 600

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
