Topics: Fractions; Modeling fractions; Conversion between fractions, decimals, and percent
CCSS: 3.NF.A.1, 3.NF.A.3.C, 3.NF.A.3.D, 4.NF.C.6
Overview: This interactive tech tool models and represents fractions. It shows numerators from 0-100 and denominators from 1-25. The fraction is modeled through length, area, region, and set models. Along with this, it states different representations for the fraction: mixed number (if applicable), decimal, and percent. Individual fraction amounts can be saved for reference and printed.

CCSS: 3.NF.A.3.A, 3.NF.A.3.B, 4.NF.A.1
Overview: This tech tool lets you build equivalent fractions. You can use circles or squares. It allows you to see 3 equivalent fractions at once. Along with the fraction models, users see the the numerical fractions represented on a number line.

Topics: Fractions; Number lines
CCSS: 3.NF.A.2, 3.NF.A.2.A, 3.NF.A.2.B
Overview: Match the Fraction is a tech tool to match the fraction on the number line. Students are given a fraction and students will need to decide how many “slices” the number line needs to be partition into. Then, students will click on the fraction on the number line that matches with the fraction that was given. Result will include an explanation of what the final numerator and denominator means in that fraction.

Topics: Fractions; Modeling fractions; Equivalent fractions; Simplest form
CCSS: 3.NF.A.3, 4.NF.A.1, 4.NF.A.2
Overview: In this game, users reduce the fraction on the screen to the lowest terms by clicking the correct answer. There are two different versions of the game. In game 1, users match the given fraction (e.g. 4/16) with the model that represents 4/16 in simplest form. In game 2, users match 4/16 with the numerical fraction in simplest form. For each game, there are three levels of complexity. Finally, users then can select to play in relaxed mode or timed mode.

Topics: Fractions; Modeling operations; Arrays; Part of a whole
CCSS: 3.NF.A.3, 4.NF.A.1
Overview: Students help Roly, the cat, by flipping the correct equivalent number of pancakes shown in fraction form on the order. Each round has new fraction and whole number factors. The whole number represents the total amount of pancakes. The pancakes on the griddle are either presented as an array or as scattered.
Cost: Free (teachers do need to buy a premium account if they want to assign it to students)

Topics: Fractions; Area model; Modeling operations; Fraction multiplied by a fraction; Part of a part
CCSS: 5.NF.B.4, 5.NF.B.5.B, 5.NF.B.6
Overview: In this tech tool, users interact with a virtual manipulative to demonstrate multiplying a fraction by a fraction. This mathematical concept is represented as an area model. Users select a crop (e.g. blueberries) and a problem to solve. The applet then guides users through the problem solving steps.

Topics: Fractions; Fraction division; Keep Change Flip; Modeling operations
CCSS: 5.NF.B.3
Overview: This tech tool models a ÷ b division. The dividend is represented as pizzas and the divisor is represented as students. Users can choose between having one to six pizzas and one to six students. The dividend and divisor are then shown as a word problem and as visuals. The applet guides users through solving the division problem as an illustration and as an expression.
