Look at the example number sentence 49-26
Do you see that using the Split Strategy for subtraction you:
First of all write how many tens there are in each number and take the lowest number of tens away from the highest number of tens to find how many tens are left.
Next write how many ones there are in each number and take the lowest number of ones away from the highest number of ones to find the total number number of ones left.
After that ADD these two totals together- that is the total of tens left AND the total of ones left.
Finally you write this total in the final line as it is your answer.
Now it's your turn.
