About this Tutorial

This tutorial is intended to:

Introduce all the tools in the app Illustrate a sample activity that can be done

using the app

What is Fraction Mash? Fraction Mash lets you explore

fractions while creating photo mashups.

Fraction Mash was inspired by combining images and photo effects

We developed a tool that allows students to explore concepts at the heart of fractions:defining the whole,denominators, numerators, and more.

Fractions

Fractions(Believe it or not, you’re doing math)

In this app, when you make your mashups, you’re breaking the pictures into fractional parts.

The grids partition the pictures.

The fractions control the size of the pieces and how many appear in each photo and in the final mashup.

Sample Activity: Simple Face Mashup

Create a mashup

• Create four different mashups

• For each mashup start with the same two faces

• In the first mashup use denominator of 4, in the second use 9, then 16 and 25.

To get started, tap:

TELL THE STORY is covered later in this tutorial.

This openingscreen showsdog and tiger,but you can import pictures fromyour camera roll or take new pictures.

Start with2 pictures

Tap the mountain button to import new pictures or take a new one.

When taking a new picture, you can reverse the camera for selfie view, turn on the fraction grid, and/or overlay withthe other image to line up features like eyes, nose and mouth.

Click the button to the right to take the picture.

Tap parts or use the fractions to control how much of each picture ends up in your mashup.

Scroll through denominators to select how many parts to cut up your pictures into. Scroll through numerators to indicate how many parts you want to mash.

Then click Combine to see what the mashup looks like.

Once you have your mashup, you can toggle on/off the Grid, the Equation view, and Smooth tool, a subtle blending feature.

Continue with the Face Mashup activity until you get to 25ths.

Here we are in equation view so you can see how everything comes together. Be sure to save your mashups for each denominator you use in the Face Mashup activity.

There you have it…4 mashups with denominators 4, 9, 16, 25.

Notice the other grid options along the bottom of the screen.

Grid options

Select custom grid, then editrows andcolumns by swiping up and down.

This grid option allows for students to define how the whole gets partitioned into equal parts.

The possibilities for mashups and exploring math at the same time are endless.

Tell the Story

Fraction Mash also allows students to create a multi-media reflection report about their projects in TELL THE STORY.

Tap:

Create a Reflection Report

Tap “+” to create a new report or tap on a report you’ve already made to access it, edit it, or share it.

Create a Report

You are given a few template options.

Blank allows you to customize your reflection.

Create a Report

In this template, notice that you can edit the title and subtitle.

Then, start adding media and/or text with different layout options.

Create a Report

Here we chose to add the mashup we made in Fraction Mash.

Tapping the “+” allows you to continue adding text and media.

Create a Report

Adding screenshots and text is a great way to reflect on what you made and the math you have used in Fraction Mash.

Teachers are invited to scaffold the reflection as they see fit by offering students suggestions for what to include.

Create a Report

Once the reflection report is complete and you have effectively told the story, you have the option to share to our online hub.

Visit noticing.nysci.org/resources for ways to share work.
