Present a problem: Suppose I told you that the second equation used to be correct before someone erased the decimal points that were in the addends. Can you figure out where to insert decimal points so that the sum of the three addends would actually be 2. How would you do this? How do you think your students would decide? Explain how I created the puzzle: Then I might show the class how I created the puzzle, choosing three numbers first and adding them. Your puzzle can have two or three addends. Follow these directions:. When all students have made at least one puzzle card, collect them, shuffle them, and distribute them to students or partners to solve.

If you have a Math Menu, add this to the options. For information about Math Menus, check a previous blog I wrote. I will be teaching decimals to my fourth graders soon in an accelerated plan where they are actually taught fifth grade standards and will use these ideas. Thank you for the ideas. I love these! I have used similar puzzles with students ranging from grades 2 through 7.

I wrote about two early lessons here:. The second lesson was with a class of highly motivated 6th grade students. Then, I worked with a 5th grade class, using what I had learned from the other students.

### Equivalent Decimals

We warmed up with a few of the more challenging whole number problems. The only catch is that you can only change a digit by multiplying it by a power of 10, , etc. We kept the discussion brief. I was looking to illuminate some thinking about reasonableness and estimation. And they were off. Like you suggested, I had some kids create their own.

I gave examples on the blog. Is actually much harder because it involves some numbers that paired together nicely 0. I like that you started with reasonableness! I knew I wanted to center my closing discussion on noticings about place value to address those 5th and 6th grade PV standards.

These puzzles have so much potential! Thanks so much, Jenna, for your detailed comment. Your suggestions will truly help. Thanks so much for this blog and all of your other meta-cognitive blogs which help us get inside your math mind and help us to nurture and develop our own math minds. I will try this with my pre-service teachers. We finally went back to school today and we got to try out the decimal lesson you created last weekend. It went pretty much as you described in the blog. We estimated then talked about why the answer was reasonable.
