Addition Strategies Learned in Class…

Show All Totals for Addition

Step 1: Add the Tens

Step 2:Add the Ones

Step 3: Find the Teen Total

Step 4: Find the Ones Total

Show All Totals…cont.

Expanded Method for Addition

Write each addend in Expanded Form (stretch the numbers out using an equation) Add the hundreds together Add the tens together Add the ones together Add all the sums together to get the final answer

Ungrouping Method for Subtraction

Write the equation. Determine if you have enough ones and tens to subtract. If you do not have enough ones to solve your subtraction problem, break apart both numbers into tens and ones (similar to expanded method for addition). Look at the tens column. Cross out your largest ten and take away ten from that number

Ungrouping Method for Subtraction…cont. Transfer the ten to the ones and add ten ones. This should create a new group of tens and ones that you should be able to accurately subtract now. Add back up your new tens and ones to get your answer.
