What type of peanut butter sandwich do you like?
We all like our peanut butter sandwiches a little differently than
others. That is what makes us unique.
We also learn differently.We can use different strategies to
solve a double digit addition problem and still
come up with the same answer.
What type of peanut butter sandwich do you like?
On the next few slides are some strategies that you can use to solve
the following problem:
Some may work for you and some may not. It’s OK!!
Traditional Algorithm
1 5 6+ 2 9 7 5
Add 6 and 9 to get 15. Put the 1 ten from 15 above the 5 in the
tens side. It is put up there because it still needs to be
added. Put the 5 ones below the 9.
How do YOU solve your addition problems?
Using the paper your teacher passed out to solve the following addition problem using a strategy that is
easiest for you.
Be creative! You may invent your own!
