K12 Equivalence Tiles

By K12 Inc.

Open iTunes to buy and download apps.


K12 Equivalence Tiles lets you compare the values of fractions, decimals, and percents up to 1 by using draggable tiles of varying values.

Fractions, decimals, and percents are used in everyday life—this app is a quick way for students to understand how they relate simply by dragging and dropping tiles of equivalent value. K12 Equivalence Tiles is not a calculator; it is a tool for students who have trouble understanding rational number equivalence (for example, 0.5, 1/2, 50% are all equal). This tool also allows students to visually perform simple operations like addition, subtraction, comparison, and ordering.

-Simple drag-and-drop controls for grade 3–12 students, parents, and teachers
-Proportionally sized tiles visually demonstrate equivalence
-Multiple rows to compare several fractions, decimals, or percents at once
-Fraction tiles of 1/1, 1/2, 1/3, 1/4, 1/6, 1/8, 1/10, and 1/12
-Decimal tiles of 1.0, 0.5, 0.33, 0.25, 0.2, 0.166, 0.125, 0.1, and 0.083
-Percent tiles of 100%, 50%, 33.3%, 25%, 20%, 16.6%, 12.5%, 10%, and 8.3%
-Equivalence chart shows how fractions, decimals, and percents relate to each other
-“Clear All” icon allows users to clear the entire workspace with a simple click
-Move draggable tiles to trash can individually to remove selected tiles from the workspace

Key Objectives and Standards:
-Big Idea: Equivalence is a fundamental property of rational numbers; equivalent fractions, percents, and decimals all name the same relationship between two values.
-Grade 3 Common Core Standards: 3.NF.1, 3.NF.2, 3.NF.3
--Develop understanding of fractions as numbers.
-Grade 4 Common Core Standards: 4.NF.2., 4.NF.3, 4.NF.5, 4.NF.6, 4.NF.7
--Extend understanding of fraction equivalence and ordering.
--Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.
--Understand decimal notation for fractions, and compare decimal fractions.

Customer Reviews

Disappointingly non-engaging

Since our youngest daughter was 18 months old we have used a multitude of educational apps to engage all of our kids in a fun learning environment.

With our eldest daughter and son both attending FLCCA, the k12 virtual academy, we have been impressed with the level of technology being used as learning tools via the online portals.

I assumed that the iPad apps would be just as engaging and provide the highest level of education possible that is aligned with the new common core standards. To my dismay, this math app only allows students to visualize the very basic ideas. There is no way to learn more advanced fractions, decimals or percentages.


I am enrolled in the k12 school pavcs and i have trouble with decimles and this helps me real well
