Base Ten Blocks
Draw base ten blocks to represent:
5 tens + 12 ones = ___ tens + ___ ones
6 tens + 2 ones
Add 198 + 201
198 + 201 = 399
(8 tens + 4 ones) - (7 tens + 3 ones)
answer as tens and ones
1 ten + 1 one
9 tens and 2 ones
Estimate by rounding to the nearest ten.
58 + 32
60 + 30 = 90
Draw base ten blocks to add 48 + 31.
48 + 31 = 79
Add 537 + 3 + 6
537 + 3 + 6 = 546
Subtract 100 - 68
100 - 68 = 32
Regroup 2 hundreds, 43 tens, and 19 ones
6 hundreds, 4 tens, 9 ones
Estimate by rounding to the nearest hundred.
345 + 288
300 + 300 = 600
87 - 36 = 51
Add 4503 + 98
4503 + 98 = 4601
Subtract 684 - 4 - 20
684 - 4 - 20 = 660
Draw base ten blocks to regroup 15 hundreds, 12 tens, 34 ones
1 thousand, 6 hundred, 5 tens, 4 ones
Estimate by rounding to the nearest thousand.
3875 - 2385
4000 - 2000 = 6000
Use base ten blocks to add 238 + 176
238 + 176 = 414
3947 + 2843 = 6790
Subtract 8452 - 2864
8452 - 2864 = 5588
278 students are going to travel by bus. Each bus holds 98 students. Two buses are full, how many students are on the third bus?
278 - 98 - 98 = 82
7462 - 4839
7500 - 4800 = 2700
Use base ten blocks to subtract 1392 - 189.
1392 - 189 = 1203
24830 + 4875 + 234 = 29939
Subtract 29650 - 8634 - 298
29650 - 8634 - 298= 20718
Zayn sold 56 tickets on Monday and 36 tickets on Tuesday. He sold 12 tickets each on Wednesday, Thursday, and Friday. How many tickets did Zayn sell altogether?
