Applet Name, Description, & URL Image Note(s) Problem Example(s) Fraction Relationship with Visual Models This applet lets you compare fraction bars as well as shows a fraction on the number line. https://www.geogebra.org/m/mHzZUgzU

This app is helpful as students need to see part to part and part to whole when using tape diagrams.

Fraction Relationship with Visual Models This applet lets you compare fraction bars as well as shows a fraction on the number line. https://www.geogebra.org/m/MtcDy6zC

This app is helpful as students need to see part to part and part to whole when using tape diagrams. The relationship is written with a symbol and words.

Bounded Fraction Pointer (Interactivate) This applet lets you compare fraction area models associated with a number line http://www.shodor.org/interactivate/activities/BoundFractionPointer/

This applet helps students see fraction size in an area model and location on a number line. The ability to show the fraction in a number of different representations is useful.



Locating Fractions on a Number Line (1) This applet lets you order fractions on a number line. https://www.geogebra.org/m/Wyphpjah

This applet helps students see fraction size and location on a number line. This is a helpful prerequisite for work with number lines and double number lines.

Comparing Fractions using Number Lines and Circles This applet lets you set up two fractions and compare size on a number line. https://www.geogebra.org/m/YQmTYBFY

This applet helps students see fraction size and location on a number line. This is a helpful prerequisite for work with number lines and double number lines.

Comparing Two Fraction Bars This applet lets you set up two fractions and compare size of the shaded parts of the bars. https://www.geogebra.org/m/taKHRjaF

This applet helps students see fraction size for improper fractions.



Diagram Templates for Ratios This applet lets you set up a ratio and select various types of visuals using that ratio from a dropdown list. https://www.geogebra.org/m/cHUztv6H

This applet helps students set up various visuals during problem solving, and can be used to compare different visuals. Educators can use the tool to create diagrams for handouts and other resources.

Example: It takes 2 yards of fabric to make tableclothes for 5 small tables.

Visual Tools for Ratios (1) This applet lets you set up part-‐to-‐part or part-‐to-‐whole relationships to be used to help solve a ratio problem. https://www.geogebra.org/m/K3WhNuSM

This applet helps students when they are trying to find the number of something when given a part-‐to-‐part or part to whole ratio.

Example: There were 2 cats out of the total 5 pets. If there were 20 pets, how many were cats?

Mixing Paint This applet lets you set up problems related to mixing paints. You need to designate the ratio then you can see different diagrams including two tapes, one tape with the total, a circle area model, or you can draw your own. You can draw on the applet to help solve the problem. https://www.geogebra.org/m/FBT7YXDZ

This applet helps students when they are trying to visualize mixing problems. The ability to show the fraction and percent is helpful scaffolding.

Example: The ration of green to white paint is 3 to 5. If there are 9 cups of green, how many cups of white are needed?



Comparing Mixtures This applet lets you set up problems related to mixing paints. You need to designate the ratio then you can set up a second ratio to compare. https://www.geogebra.org/m/skqDWFbm

This applet helps to see the same relationship across 2 representations.

Example: You have a ratio of 3 green to 5 white, if you put in 6 green, how many white do you need? The students can see the color, volume, & ratios as fraction and percent.

Using Ratios to Mix Paints This applet lets you set up problems related to mixing paints. You need to designate the ratio then two out of three parts of the problem. It checks your answer to the problem. https://www.geogebra.org/m/UWyJEuSN

This applet helps students by providing the problem in text and also generates a visual to help solve the problem.

Example: Mixing paint 3 parts green to 5 parts white. If you have 6 cups green and 10 cups of white, how much mint colored paint do you make?

Double Number Line (1) This applet lets you set up a double number line given the ratio between two items. https://www.geogebra.org/m/XUMdVduR

This applet can be very useful when setting up double number lines. It can also be used to help reinforce unit rates.

Example: If Jose has 2 shirts to every 6 shoes in his closet, if he has 7 shirts, how many shoes does he have?



Double Number Line -‐ Percent Change This applet lets you set up a double number line for percent change problems by dragging a handle to see the percent change. https://www.geogebra.org/m/EwBMADEE

The applet can be used to explore and answer percent change problems. The requirement to click and drag the blue handle reinforces the change from 100% and the value for the whole.

Example: The wholesale price of a toaster is $20. The store marks up the toaster 50%.

Double Number Line -‐ Percent Change (2) This applet scaffolds users through a process for setting up percent change problems on a double number line by entering numbers. https://www.geogebra.org/m/Gdj6JVJK

This applet can help model and reinforce a process for answering percent change problems.

Example: A $30 widget is on sale for 25% off.

Solving percents with a bar model This applet lets you set up and use a bar model as well as ratios, a table, and an expression. https://www.geogebra.org/m/fb4kWrTt

This applet can help with setting up a bar model for percents and relating the visual bar model to other representations of the relationship.

Example: If the regular price of a dishwasher is $220, what is the sale price if the dishwasher is 60% off?
