Easy as Pie Fractions

thingiverse

Easy as Cake Fractions is a small fraction cake that was designed to help individuals to small groups learn how to add, subtract, multiply and divide ten different fractions, 1/1, 1/2, 1/3, 1/4, 1/5, 1/6, 1/8, 1/10, 1/12, and 1/16. Each piece of cake has the accompanying decimal point. The cake tin allows for a snug fit between the pieces, but the frosting on the cake allows for easy removal of individual fractions. This hands-on learning tool helps people who are struggling when it comes to understanding fractions by allowing them to physically manipulate fractions. The fraction cake pieces can be utilized in various lesson plans from beginner (e.g., adding fractions to make a whole) to intermediate (e.g., multiplying different fractions to create a mixed number). Please post your makes because I am interested in what you have used it for. Also feel free to comment on anything you would like me to add. As always, any tips are greatly appreciated and will go towards the development of future projects. Print Settings Printer: Monoprice Maker select 3D printer Rafts: No Supports: No Resolution: 0.1 layer height Infill: 20% Piece of cake fraction was a test run to see if I could get the fractions to print correctly, and it worked out great! Overview and Background Easy as Cake Fractions are for children or adults who would benefit from a visual and tactile aid in helping them understand fractions. Lesson Plan and Activity To complete this project, you have to identify what specific fractions the students have trouble with and print out enough pieces to fill each cake tin. Lesson Plan Ideas -Adding fractions to make a whole -Adding fractions to make another fraction -Subtracting fractions from a whole -Subtracting fractions from another fraction -Multiplying fractions to make a whole -Multiplying fractions to make another fraction -Is dividing the same thing as a fraction? -Dividing whole numbers -Dividing fractions Materials Needed 3D printer and filament Project: Easy as Cake Fractions Project Name: Easy as Cake Fractions Overview & Background: Easy as Cake Fractions are for children or adults who would benefit from a visual and tactile aid in helping them understand fractions. Objectives: The students who use this are expected to learn how to add, subtract, multiply, and divide simple fractions. This hands-on approach will also give students a better understanding of the reason behind their calculations. Audiences: Easy as Cake Fractions is designed for children between the grades 1st through 5th but can be used and enjoyed by people of all ages. Subjects: Easy as Cake Fractions is designed to be used individually or in small groups in a math class or club. Skills Learned (Standards): Students should have learned how to add, subtract, multiply, and divide the fractions provided. Lesson/Activity: To complete this project, you have to identify what specific fractions the students have trouble with and print out enough pieces to fill each cake tin. Lesson Plan Ideas -Adding fractions to make a whole -Adding fractions to make another fraction -Subtracting fractions from a whole -Subtracting fractions from another fraction -Multiplying fractions to make a whole -Multiplying fractions to make another fraction -Is dividing the same thing as a fraction? -Dividing whole numbers -Dividing fractions Duration: Easy as Cake Fractions can take as little or as long as you want to spend working on fractions with your student. It can be used every day for group work with fractions which is what it was designed for. Preparation: Before students begin using Easy as Cake Fractions, they need to know how to add, subtract, multiply, and divide whole numbers. They don’t actually need to know how to manipulate fractions with pen and paper. For example, if 1/2 and 1/4 are printed out, the students can physically see how the half would divide into two pieces and so on. References: No References. Rubric & Assessment: At the end of the project, the student should be able to understand the concept(s) addressed, depending on the specific lesson plan objective(s) chosen. If, for example, the objective was to learn the concept of adding fractions to make a whole, the student should be able to understand that three 1/3 pieces make a whole, four 1/4 pieces make a whole, five 1/5 pieces make a whole, etc. Handouts & Assets: No Handouts and Assets.
