______
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
