Time for a quick quiz!
How many different problem types are there for addition and subtraction word problems?!?!
Yes! There are 12 different problem types for addition and subtraction word problems. When I first learned about the different types I realized I was not exposing my students to all of them. At first it was challenging for me to remember to ask these questions in all these different ways. I started with my youngest learners and have moved up through the grades. In the past I have written about how I address these different problem types at the fact level and with multi-digit addition and subtraction. Today I want to share with you how I address these problem types in the context of fraction addition and subtraction.
A great place to find examples of the different problem types is table 1 in the appendix of the Common Core. If you are new to these problem types, you might want to print yourself a copy and keep it handy. It is a great way to make sure your students are getting the exposure they need!
Just being aware of the different types of problems is a big step in the right direction. I highly recommend you sit down and write a few problems of each type that are at a good level for your students. This is what I did with fractions. Because it is December and school schedules are crazy, I made mine into reindeer themed task cards. This way we can try a few problems at a time and I can use them again in math centers.
|This problem is a take from, change unknown|
|This problem is put together/take apart total unknown. I have a collection of reindeer antlers that are apparently fun to wear when doing these problems!|
|If you have a Christmas tree in your classroom, decorating it with task cards can lead to some fun times!|
If you are looking for more information about the different problem types and a lot more examples, you might want to grab a copy of Children's Mathematics or check out our book study!
