PhET: Make a Ten
Add numbers by making tens. Break apart and combine numbers while focusing on place value. Use the adding screen to add any two numbers. Use the game screen to apply your make-a-ten strategies!
PhET: Fractions: Mixed Numbers
Explore fractions while you help yourself to 1 and 1/2 chocolate cakes and wash it down with 1/3 a glass of water! Create your own fractions using fun interactive objects. Match shapes and numbers to earn stars in the mixed number game. Challenge yourself on any level you like. Try to collect lots of stars!
PhET: Build a Fraction
Build fractions from shapes and numbers to earn stars in this fractions game or explore in the Fractions Lab. Challenge yourself on any level you like. Try to collect lots of stars!
PhET: Isotopes and Atomic Mass
Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.
PhET: Unit Rates
Discover the unit rate while shopping for fruits, vegetables, and candy. Construct a double number line and look for patterns. Challenge yourself on the race track as you compare cars with different rates!
PhET: Molecule Shapes
Explore molecule shapes by building molecules in 3D! How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare the model to real molecules!
TED-Ed: Value of the Arts Lessons
TED-Ed celebrates the ideas of teachers and students around the world. Discover hundreds of animated lessons, create customized lessons, and share your big ideas.
PhET: Molecule Shapes: Basics
Explore molecule shapes by building molecules in 3D! Find out how a molecule's shape changes as you add atoms to a molecule.
PhET: Natural Selection
Explore how organisms with different traits survive various selection agents within the environment.
PhET: Number Line: Operations
Explore operations with integers using an authentic context of net worth, then generalize with a number line. Experiment with adding and subtracting both positives and negatives, and make predictions about whether the total will be positive or negative.
PhET: Number Line: Distance
Subtraction is more than an operation- it is also the distance between two numbers! Explore the distance between a person and house, a bird and a fish, and the difference in temperature between two locations. Compare absolute distance and directed distance, and strengthen your number line muscles.
PhET: Number Compare
Compare numbers represented as numerals, objects, groups, and ten frames. Use a sentence, number line, or stacked units to determine the larger group. Hear the comparison spoken aloud in two different languages.
PhET: Area Model Introduction
Build rectangles of various sizes and relate multiplication to area. Partition a rectangle into two areas to discover the distributive property.
PhET: Molecule Polarity
When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity.
PhET: Balancing Chemical Equations
How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!
PhET: Gene Expression Essentials
Express yourself through your genes! See if you can generate and collect three types of protein, then move on to explore the factors that affect protein synthesis in a cell.
PhET: Atomic Interactions
Explore the interactions between various combinations of two atoms. Observe the total force acting on the atoms or the individual attractive and repulsive forces. Customize the attraction to see how changing the atomic diameter and interaction strength affects the interaction.
