This lesson was written to provide enrichment to fifth grade students on addition and subtraction of fractions with both like and unlike denominators. This activity allows the student to have enrichment in a fun, hands-on way utilizing a real-life activity.

Numerator:  The number on top of the fraction bar.  It names parts of a whole.

Denominator:  The number on the bottom of the fraction bar.  It names how many parts a whole is

                            broken into.

Common Denominators:  Fractions that have the same denominators.  (Like Denominators)

Uncommon Denominators:  Fractions that have different denominators. (Unlike Denominators)

Fraction Bar:  The symbol in a fraction that separates the numerator and denominator.

• Students will add and subtract fractions with like and unlike denominators from the student-made recipe book.

This lesson should take approximately two 40 minute class periods to complete.

Webb’s Depth of Knowledge:  Skill/Concept, Strategic Thinking, Extended Thinking

W: WHERE/WHY/WHAT

This lesson is most appropriate for students who have an initial knowledge of addition and subtraction with like and unlike denominators.  It will provide enrichment using a real-life activity.

H: HOOK

This lesson will allow students to have the opportunity to embrace the math skills in fractions acquired in fifth  grade and apply them in a fun, real-life way.

 

E: EXPLORE/EXPERIENCE/EQUIP

 

This lesson provides students the opportunity to utilize technology and a real world activity in math.  Students will be able to create and publish their own recipe in the student-made recipe book.

 

R: RETHINK/REHEARSE/REVISE/REFINE

 

Students will be typing their recipes and having them published.  Students will then be using classmate’s recipes to answer real-world math problems.  They will be adjusting the amounts of ingredients depending on chosen recipes.

 

E: EVALUATE

 

Students will be informally assessed during activity via teacher observation and circulation.    Teacher will formally assess the posters using the assessment checklist upon completion.

T: TAILORED

This lesson is tailored to a fifth grade student who has initial knowledge of addition and subtraction of fractions with both like and unlike denominators.

O: ORGANIZED

 

Activities will be organized into introduction, work time, guided review and activity completion time.

1.  Teacher will hand out Recipe Assignment Page three days prior to lesson. This will allow students time to get a recipe and write it down for the lesson. Teacher will assign a due date.
2. On due date, teacher will have the students type or handwrite their recipes.  They should include ALL PARTS of the Recipe Assignment Page.  Teacher will monitor closely that all parts, especially the amounts of the food needed are included. (If typing, before students may print, teacher must approve the recipe.)  Students should draw a picture or use clipart of the food on the bottom or back of page after printing.
3. Teacher Step:  Teacher will gather all recipes and form into a book for the students.  These can be copied and stapled.  Teacher should be sure to separate book into categories (appetizers, desserts, etc…).
4. Activity Day:   Teacher will hand out recipe books.  Teacher will give students a few minutes to look over.  Then teacher will say, “Class, we will be working with these recipes today.  I would like to figure out how much butter I need to make (example) Jessy’s cake and Jim’s cookies.  Please find the two recipes in the book.”  Teacher will ask volunteers to tell the butter needed for the two recipes.  Teacher will model how to add them together.  (This is review due to being an enrichment lesson.)
5. Teacher will then ask a similar subtraction question. (Example) “How much more milk does Pam’s Pudding have than Tony’s Banana Bread?” Teacher will model a subtraction problem.
6. Teacher will then pass out the assessment page.  Teacher will have the students complete number one independently and go over together.  Teacher will monitor closely and have students correct any errors.
7. Students will then complete assessment page individually for a grade.
