Math Games has carefully tailored its wide selection of games for 5th graders to the Common Core State Standards for Mathematics. As well as being academically rigorous, our games are seriously fun! As pupils play, they can review math skills such as:. With Math Games, the learning process is an enjoyable game and math review is something to look forward to.

## Teaching Adding Decimals: What If You Give the Answer First?

Welcome to Match Fishtank , where you can view, share, and download the curriculum we use every day at Match Charter Public School, the PreK charter public school that we opened 20 years ago in Boston. These materials have been developed and curated by our teachers and curriculum experts over many years. Except as otherwise noted, the curriculum made available at matchfishtank. Unit Prep. Lesson Map. Unit Summary. Assessment This assessment accompanies Unit 1 and should be given on the suggested assessment day or after completing the unit.

Suggestions for how to prepare to teach this unit. As Nina and I talked, I recalled an idea. Please let me know if you have a source. I offered Nina this instructional suggestion:. Ask: Is a reasonable answer for adding plus 47 plus 9? How could you explain without adding the three numbers? Actually, I asked Nina to write the equation horizontally on paper, since we were on the telephone. Ask: Suppose I had written this on the board instead and asked the same question: Is 2. How would you explain? What would you answer?

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.
