21. 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

22. 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 = _____

23. 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

24. I can add and subtract mentally when it makes sense to do so. Solve mentally: a)8 + 6 = ____ b)80 + 60 = _____ c)800 + 600 = ______ d)10 – 4 = ______ e)100 – 40 = ______ f)1000 – 400 = ______

25. I can add and subtract mentally when it makes sense to do so. Solve mentally: a)8 + 6 = 14 b)80 + 60 = 140 c)800 + 600 = 1,400 d)10 – 4 = 6 e)100 – 40 = 60 f)1000 – 400 = 600

26. 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!

27. 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 didnt need to calculate because I could just look at the related problem.)

28. 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 = ________ cookies Now, write a related addition problem, using all three of the numbers from the cookie problem. Get your answer to the problem without calculating!

29. 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 didnt need to calculate because I just looked up at the related problem.)

30. 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?)

31. 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
