Decide if each statement is true or false. If it is false, give the correct answer.

1. \(300 + 400 = 700\)
2. \(800 - 300 = 400\)
3. \(250 + 250 = 500\)
4. \(750 - 250 = 400\)

8 Regroup the ones ★★★

Add \(238 + 157\). Tell which column you regrouped.

9 Regroup the tens ★★★

Add \(374 + 283\). In which column do you need to regroup?

10 Regroup twice ★★★

Add \(486 + 349\) and show each regrouping.

14 Find the mistake ★★★

Mia wrote \(352 + 189 = 441\). Is she right? If not, find her mistake and give the correct sum.

15 Quick estimates ★★★

Use the nearest hundred for each number to estimate, then find the exact answer.

1. \(389 + 212\)
2. \(703 - 296\)

16 Subtracting across zeros ★★★

Subtract and check by adding.

1. \(600 - 357\)
2. \(400 - 168\)
3. \(805 - 449\)

17 Counting up ★★★

Use jumps on a number line to find \(531 - 268\). Write the three jumps and the answer.

18 Friendly hundreds ★★★

Use the properties of addition to find \(275 + 138 + 25\) in your head. Say which property helps you.

19 Which is greater? ★★★

Which is greater, \(468 + 275\) or \(812 - 90\)? By how much?

20 Missing number ★★★

Find the missing number. Show how you checked.
