______

450 Standard Addition Algorithm

using base ten blocks

with no regrouping 0 ones + 0 ones = 0 ones

0 tens + 5 tens = 5 tens

3 hundreds + 1 hundred = 4 hundreds 0 + 0 = 0

0 + 50 = 50

300 + 100 = 400 34 + 27 Standard Addition Algorithm

using base ten blocks

with regrouping =61 trade in 10 unit cubes

for 1 ten rod because 11 unit cubes consists of 1 unit cube and 1 ten rod =61 523

number above diagonal line is tens place

number below is ones place

next add tens place

number above diagonal line is hundreds place

number below is tens

continue this process

then add numbers along diagonal line as shown

numbers shown in red are your answer 3 Types of Addition Algorithms
