Make a Ten
Rate the resource as a perfect 10. Pupils use an interactive to help add and subtract numbers. They first explore how to express whole numbers using hundreds, tens, and ones, then explore how to add whole numbers by combining to make...
PHET
Fraction Matcher
Here's an interactive that will be a great match for math lesson plans. Young mathematicians use an interactive game to match fractions represented numerically and as fraction models. One game assesses fractions only, while the other...
PHET
Fractions: Equality
What makes fractions equivalent? Learners first use an interactive that shows equivalent fractions with fraction models and number lines. They then play a game where they must match sets of equivalent fractions with different denominators.
PHET
Fractions: Mixed Numbers
Mix up math lessons by incorporating an interactive. An educational interactive teaches users about mixed numbers. They first see how to convert between mixed numbers and fraction models. After completing the instruction, they play a...
PHET
Fractions: Intro
There's nothing improper in learning about fractions. Scholars apply an interactive to explore models for proper and improper fractions. They then answer a set of questions in a game that requires building models for given fractions and...
PHET
Expression Exchange
Bank on your ability to write equivalent expressions. Scholars use an interactive to create expressions using coins. They then convert these to algebraic expressions and figure out how to evaluate them. A game with various difficulty...
PHET
Equality Explorer: Two Variables
Solving equations in two variables can't be that much harder than solving equations in one variable. Using a balance interactive, scholars solve equations in two variables. They apply inverse operations by adding -x, -y, or -1 as...
PHET
Equality Explorer
Find the right balance between concrete and abstract thinking. After using interactive balances to explore inverse operations, learners solve multi-step equations with variables on both sides. Of course, they can still use the...
PHET
Equality Explorer: Basics
Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.
PHET
Build a Fraction
Build on knowledge of fractions to build fractions. Pupils use interactives that require building fraction models for given fractions or mixed numbers and identifying fractions or mixed numbers for given models. A lab area lets users...
PHET
Arithmetic
Three interactives times three difficulty levels equals nine possible games. Scholars play a online game that requires finding products, determining missing factors, and finding quotients. Multiplication tables are available to help...
PHET
Area Model Decimals
Area works with decimals too. Pupils use the interactive to model multiplication of two decimals using an area model. They see how the decomposed components of the factors obtain partial products and then the complete product. Using area...
PHET
Area Model Algebra
Expand the pupils knowledge of using area models to algebra. The interactive allows learners to use the same procedure of getting partial products when multiplying multi-digit numbers to multiplying polynomials. Scholars see how the...
PHET
Area Model Multiplication
Develop a solid understanding of multiplication. The interactive provides opportunities for learners to continue building a deep understanding of multiplication. Pupils use the application to find the product of two numbers and find...
PHET
Area Model Introduction
Provide two views of multiplication. The introduction to an area model application has two modes. One mode shows the area of simple multiplication up to 12 by 12. The second mode shows how area models can be partitioned leading to the...
PHET
Area Builder
All that matters is the tiles. Pupils use the interactive to investigate the relationship between area and perimeter using tiles. The interactive has an explore and a game mode to accommodate different steps in learning. The game mode...
PHET
Vector Addition
Model vector addition graphically. A simple interactive has users add vectors and adjust the lengths and angles of the vectors. The interactive automatically updates the magnitude, angle, and components of the sum.
PHET
Unit Rates
Sometimes you just want to know the cost of one apple. A fun interactive lets learners explore the unit costs of fruits, vegetables, and candy. It shows how ratios to express ratios symbolically and on a double number line.
PHET
Trig Tour
Unit circles and trigonometric graphs go hand in hand. Pupils see how traversing the unit circle allows for the creation of graphs for trigonometric functions. They also see trigonometric ratios in terms of the ordered pairs of points on...
PHET
Plinko Probability
It's a good thing the resource dropped into your radar. Young mathematicians use an app that randomly drops balls through a Plinko game and into bins. They compare the distribution to that of an ideal binomial distribution.
