Determining when objects on the screen touch is an important aspect of most games. In this lesson we'll look at how the Pythagorean Theorem and the Distance Formula can be used to measure the distance between two points on the plane, and then decide whether those two points (or game characters) are touching.

En calificaciones anteriores, los estudiantes definen, evalúan y comparan las funciones y las usan para modelar las relaciones entre las cantidades. En este módulo, los estudiantes extienden su estudio de funciones para incluir la notación de la función y los conceptos de dominio y rango. Exploran muchos ejemplos de funciones y sus gráficos, centrándose en el contraste entre las funciones lineales y exponenciales. Interpretan funciones dadas gráfica, numérica, simbólica y verbalmente; traducir entre representaciones; y comprender las limitaciones de varias representaciones.

SYNOPSIS: In this lesson, students are introduced to biomass energy and use …
SYNOPSIS: In this lesson, students are introduced to biomass energy and use algebra to calculate the amount of land needed to produce biofuel using different plants.
SCIENTIST NOTES: This lesson introduces students to biofuels and how they are sourced, including the supply chain. It does not only equip them to compute the acres of land needed to grow crops to produce biofuels but allows them to compare biofuels with other renewable energy sources, including the benefits and limitation to scale up. All the materials have been fact-checked, and they are suitable to build students' knowledge on the topic. Hence, this lesson has passed our science credibility process.
POSITIVES: -Students have opportunities to think critically about the topic of renewable energy in their community. -Students have the chance to use math in a real-world application, which makes it more relevant and engaging.
ADDITIONAL PREREQUISITES: -This is lesson 4 of 5 in our 6th-8th grade Renewable Energy Algebra unit. -This lesson could be used as a standalone lesson if desired. -There are quite a few drawbacks and challenges to large-scale biofuel production and use. Students should begin to see this through their calculations and discussion. An optional extension video is included at the end of the lesson that looks more at some of the issues with biofuel.
DIFFERENTIATION: -Teachers can have students work with a partner on the calculations in the Investigate section and purposefully group students based on skill level. -Teachers can work in a small group with students who may need additional assistance with the calculations. -Teachers can limit the number of questions students complete. Questions get progressively more difficult on the Student Document. -Interdisciplinary connections can be made with Earth science, physical science, and engineering design.

Students solve real-world problems by writing and solving equations. Students estimate the solution and determine if the estimate is reasonable before finding the exact solution. They write the solution as a complete sentence.Students complete a Self Check.Key ConceptsStudents solve real-world problems by first estimating the solution and assessing the reasonableness of the solution. Next, they write an equation to solve the problem and then use the properties of equality to solve the equation. Students write the solution to the problem as a complete sentence.Goals and Learning ObjectivesWrite equations to solve multi-step real-life problems involving rational numbers.Solve equations using addition, subtraction, multiplication, and division of rational numbers.Use estimations strategies to estimate the solution and determine if the estimate is reasonable.Write the solution as a complete sentence.

Students extend what they learned about solving equations in Grade 6. They learn to solve equations that require them to use both the addition and the multiplication properties of equality. They use what they know about solving equations such as 2x = 6 and x + 3 = 7 to solve equations such as 2x + 3 = 8. They connect solving problems using arithmetic to solving problems using equations. They solve equations containing both positive and negative rational numbers.Key ConceptsAddition property of equality: If a = b, then a + c = b + c.Multiplication property of equality: If a = b, then ac = bc.For any equation, add or subtract the same value from both sides of the equation and the equation will still be true.For any equation, multiply or divide both sides of the equation by the same value and the equation will still be true.In this lesson, students use both properties to solve equations. They then solve equations that contain both positive and negative rational numbers.Goals and Learning ObjectivesSolve equations using both the addition and multiplication properties of equality.Relate solving problems using arithmetic to solving problems using equations.Solve equations containing both positive and negative rational numbers.

In earlier modules, students analyze the process of solving equations and developing fluency in writing, interpreting, and translating between various forms of linear equations (Module 1) and linear and exponential functions (Module 3). These experiences combined with modeling with data (Module 2), set the stage for Module 4. Here students continue to interpret expressions, create equations, rewrite equations and functions in different but equivalent forms, and graph and interpret functions, but this time using polynomial functions, and more specifically quadratic functions, as well as square root and cube root functions.
