### Math Journal Sundays

Ahhhhh ... Sunday morning.  All is good.

I've got a quick little foldable to share with you today from our math journals.  We're just finishing up our Measurement unit (we've covered measuring length, metric conversions and perimeter and area of rectangles, triangles and parallelograms).  Our test is on Monday, so we spent Thursday and Friday in review.

We made a 4-corner foldable to review the formulas for the area and perimeter of the different shapes we learned.  (It was actually quite funny because as I started folding the paper under the Elmo, the kids got excited and asked if we were doing another cootie catcher ... they know me so well).  Anyhow, it wasn't a cootie catcher (this time), but it was good for review.  On the inside of each flap we found the area and perimeter of each shape (the students had to measure the dimensions of the shape they drew on the outside of each flap).

That's about it ... I'm planning on breaking the "no more than one post per day" rule today, but I've got to get a few things (ok - more than a few things) done first ... stay tuned ...

Happy Sunday!!!

1. Thank you for sharing all of your fabulous ideas. I've always used Math Journals in my classroom, but thanks to you, I have a lot more great ideas to put into them. I truly look forward to these posts.

1. Thank-you so much! This is the first year I've actually enjoyed doing math journals. I actually get excited thinking about what we'll do next.

2. I love this foldable-- is there ever a foldable I don't love?! Thanks for sharing! I love your Math Journal Sundays so much!

1. Thanks, Kate! I get so many great ideas from your blog, too!

3. I love the foldable idea. We are starting measurement on
Tuesday, I can't wait to add this to our notebooks.

4. I like this one! I may integrate it into our upcoming area unit :)

5. so timely for my current topic...thanks!

6. Thank you for showing the inside and outside of the foldable. A lot of blogs just show the outside.

7. I like the foldable but should the Perimeter have a parenthesis around the length plus width. Without solving the way you have written according to order of operations it would be wrong.

8. I love your fold-able graphic organizer, but one of your pictures is a trapezoid , not a parallelogram. A parallelogram is a shape with opposite sides parallel and equal in length.

9. How do you make the foldable? I LOVE IT!

10. I love using graphic notebooks in my 7th and 8th grade classrooms and I'm stealing this one! However, I do have some feedback about writing the formulas. On the parallelogram and rectangles you write P = l + w x 2. In the example you add first, then multiply. This violates the order of operations as written (even though the result is technically correct). I know when we practice order of operations, it's often a struggle to get students to multiply before adding and I wouldn't want this to reinforce that idea. Maybe writing it as 2 x L + 2 x w, or 2 x (l + w). I'm not sure what level you are teaching but introducing the idea of order of operations might be beneficial here!

Thanks for the great idea!
