4NF4 - What I did to teach it.

Students need to understand that fractions can be a multiple, how to multiply fractions, and solve word problem involving multiplication. This is the process I went through so that my students understood the standard. I listed the items in order as to what I taught.

Lesson 1 We decomposed frations and wrote them as multiplication expressions.

Ex: 2/5= 1/5 + 1/5...decompose the fraction first.  Ask the question...How many 5ths are there? Answer 2, therefore 2/5 is the same as 2 x 1/5.

Lesson 2 We wrote whole numbers as fractions and explained the concept of why it works with division. Students rewrote problems and then proceeded to multiply.

Ex. 3 x 1/4 = 3/1 x 1/4

3/1 is the same as 3 divided by 1 = 3

I showed models as well.

 Students solved several problems in which they rewrote the whole number as a fraction and multiplied to solve the equation.

Lesson 3 We created multiplication expressions to model multiples.

Ex: 2 x 3 = 6 x 1   therefore

2 x 3/4 = 6 x 1/4

Lesson 4 We created models of multiplication sentences.

Lesson 5 We practiced the multiplication algorithm.

Lesson 6 We practiced word problems.


Centers-I created flash cards with multiplication problems that students can solve. They also were required to create their own story problems using the cards and how to model the problems. They also created screen chomp videos that showed if they understood what they needed to do to solve these types of problems.
I will post my anchor posters when I have time. I hope this helps for those that are struggling with CCSS.

4.NF.3 Math Posters and Reader's Response Notebook

These are some of the posters I'm using for CCSS 4NF4 and a poster that my students use to help them when they respond in their reader's response notebook. Everytime I introduce or review a part of the Reader's Response Notebook I create a poster and an anchor for students to refer to because they need that visual model as a guide. I have found that CCSS is much more detailed than just using an algorithm to solve a problem. It's about how the math works. My students had difficulty with decomposing mixed numbers to improper fractions not becuase they couldn't do it, but because they didn't understand why it worked and how to apply it in math situations. Hopefully I will have time to share the units I have created which have made my life so much easier in teaching math. There isn't much math CCSS out there.

Fraction Centers

These are the fraction centers that my students are using at this time. They are easy to assemble and students can use them right away.

Paragraph Writing Cupcake Contest

For Valentine's Day I decided to have a Cupcake Contest. Students will create their ultimate cupcake and write a descriptive paragraph using a cupcake organizer. They will then draw their cupcake and include their description. Students have the opportunity to vote on the one they would like to try and the winners will get a special treat!

Literary Elements/Conflict/Paragraph Writing

 Wow things have been so busy I can't find the time for anything. So this is a collection of things my students have been working on over the past month.

We have been reading a lot of fiction and one project they created was conflict flip books. Students watched a power point that I created and then used the information that was presented to create their flip book. On the inside they list a definition and their own example from literature. They also included an illustration.



This is a picture of the burger graphic organizer that my students use for paragraph writing.

 



Help! My room has been invaded by sock snowpeople

We began our expository writing unit by creating sock puppets and students went through the process of creating them and then wrote their  "How To" which gave the material and steps to create their own. They loved it!

Synonym Unit and Center

I created this synonym unit to accompany the Common Core. There are 12 units which increase in difficulty, and students work their way through the unit. I created four different activites to go along with the unit including an assessment piece. I copy the word cards on colored paper. The copy below shows what the word cards look like. My students enjoy it!
