PRODUCT DESCRIPTION

CCSS.Math.Content.4.NF.B.3a Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
CCSS.Math.Content.4.NF.B.3b Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.

Although this activity works great for a 4th grade common core, it is also suitable to challenge third graders or for a third grade extension activity when studying fractions. It may also be suitable for a quick review for fifth grade when starting a fraction unit, as well as for math remedial students.

Click on the preview button above to see a picture of what is included.

This will work great as a math mini lesson with sheets to evaluate how well students understand it.

This includes 9 slides. They can be used in a couple of different ways. Although it is an adobe file, you can project it as a slide show. Or, you can use half of it as a slide show and there are 4 sheets that could be used as graded activities.

There is a definition sheet, 4 slides that present colorful fractions, and 4 sheets that have problems to either solve together or print for kids to complete individually. The four slides that present examples have cute fraction images for the students to decompose and find equations that will equal the starting fraction.

Feel free to use this activity in your classroom however you would like.

Thank you. I loved reading that. :-) ~Molly

Some great worksheets here for decomposing fractions. Really helped my kids do well. There is one typo on the one page with the definition of decomposing fractions (it says 'stared' instead of 'started')

This was a great RTI for some of my students who needed to back up their understanding.

Do you have any multistep word problems, fraction word problems, or any word problems showing the use of bar modeling for the upper grades? mccrumjk@schenectady.k12.ny.us
Hi - I don't think I have anything at this time that would fit that criteria. I will add that to my list of things to make. :-) ~Molly
