How to add using the hundreds chart

Your addition problem

Choose the larger addend and circle it on your hundreds chart.

Then add the tens part of 27....which is 20. Jump down a row for each ten. Count "10...20"

Next add the ones...which is 7. This time we will jump horizontally one box at a time. Count "21, 22, 23, 24, 25, 26, 27." Circle your answer, the sum...73.

This time let's try starting at 27.

Jump down 4 rows to add the 4 tens in 40. "10, 20, 30, 40."

Then add the 6 ones. "41, 42, 43, 44, 45, 46.". Circle your answer.

Either way, your sum is 73.
