Rolling dice is the best way to show your learners how probability comes in to play. Although this lesson does not specify an activity, your mathematicians can try this probability with real dice to calculate their experimental...

Calculate theoretical probabilities and compare them to experimental probabilities. Pupils build on their knowledge of experimental probabilities to determine theoretical probabilities. Participants work several problems with the...

In this chemistry olympiad lab worksheet, chemists are required to design two experiments. In one, they design an experiment to identify seven solutions given to them in pipettes. In the other, they design an experiment to determine the...

In this chemistry olympiad laboratory activity, learners design and carry out two experiments. They design one experiment to test for the percent mass of a substance in a solution and they design another experiment to identify two...

Flip a coin to determine whether the probability of heads is one-half. Pupils use simulated data to find the experimental probability of flipping a coin. Participants compare the long run relative frequency with the known theoretical...

In this chemistry Olympiad worksheet, pupils are given 2 lab problems to work on. They must explain their experiment they would carry out, show their data and write their results and conclusions of the lab and the process.

Are American young people prepared to become tomorrow's leaders in technological innovation, or does an obsession with being cool sidetrack essential skills? That is the question freshmen and sophomores must address in a performance...

Opening up a package of fruit snacks is like a box of chocolates, you never know what you're going to get. When all the mango flavored ones are missing, learners calculate the probability that one bag versus the whole box is missing the...

Challenge young mathematicians' understanding of squares with this geometry puzzle. The task is simple, identify as many squares as possible in a 3x3 array. Allow learners to work independently or in pairs as they search for squares,...

Use a performance task to assess third graders' ability to read informational text. After they plan a lemonade stand business, young entrepreneurs implement that plan through informational writing. The task assumes learners can...

After reading the first, second, and third parts of "How Bear Lost His Tail", third grade writers answer questions about the story by completing a series of options, including discussion points. Then, they begin to plan a new narrative...

Is it crazy to fall in love with your own work, or is that the purest love of all? Compare two renditions of the classic Greek myth Pygmalion and Galatea with a literary analysis exercise. After students compare the similarities and...

A three-part assessment challenges scholars to write opinion essays covering the topic of the student council. After reading three passages, writers complete a chart, work with peers to complete a mini-research project, answer...

Which animal is best for you—a dog or cat? Why? Engage third graders in an opinion writing assessment that prompts them to read facts about both pets, and then write and decide which pet is best for them.

On June 26, 1963 President John F. Kennedy delivered his famous "Ich bin ein Berliner" speech close to the Berlin Wall at the Rudolph Wilde Platz. On June 12, 1987 President Ronald Reagan Delivered his famous "Mr. Gorbachev, tear down...

Technology has undoubtedly improved the lives of people around the world—but has it improved communication? Seventh graders read two informative passages about the rise of texting and emailing versus in-person conversations before...

Test mathematicians' knowledge of adding fractions with a brief assessment that challenges them to play teacher while correcting a peer's work. Scholars examine Carl's mathematical response, identify where he went wrong,...

Geometers prove that triangle PQR is congruent to triangle ABC by describing any combination of rotations, reflections, and translations that would prove it so. There is only this single task on the handout, but a detailed explanation of...

Teach your class how to apply their knowledge of geometry as they explore the unknown. In order to find an unknown angle, students must understand that rectangles have four interior right angles, that right angles have 90 degrees, and...

Start off with the definition of the imaginary number i, then have your class practice simplifying expressions involving powers of i and look for patterns. See how the cyclic nature of powers of i translate to sums of powers of i.
