Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Students experiment with various ways to naturally dye materials using sources found in nature—roots, leaves, seeds, spices, etc.—as well as the method of extracting dyes. Then they analyze various materials using statistical methods and tackle an engineering design challenge—to find dyes that best suit the needs of a startup sustainable clothing company.

Given an inverse trigonometric function, this lesson demonstrates how it can be evaluated for a particular value. It is 6 of 7 in the series titled "Evaluating an Inverse Function." [3:26]
In this final module of the Grade 1 curriculum, students bring together their learning from Module 1 through Module 5 to learn the most challenging Grade 1 standards and celebrate their progress. As the module opens, students grapple with comparative word problem types. Next, they extend their understanding of and skill with tens and ones to numbers to 100. Students also extend their learning from Module 4 to the numbers to 100 to add and subtract. At the start of the second half of Module 6, students are introduced to nickels and quarters, having already used pennies and dimes in the context of their work with numbers to 40 in Module 4. Students use their knowledge of tens and ones to explore decompositions of the values of coins. The module concludes with fun fluency festivities to celebrate a year's worth of learning.

Students' eyes are opened to the value of creative, expressive and succinct visual presentation of data, findings and concepts. Student pairs design, redesign and perform simple experiments to test the differences in thermal conductivity (heat flow) through different media (foil and thin steel). Then students create visual diagrams of their findings that can be understood by anyone with little background on the subject, applying their newly learned art vocabulary and concepts to clearly communicate their results. The principles of visual design include contrast, alignment, repetition and proximity; the elements of visual design include an awareness of the use of lines, color, texture, shape, size, value and space. If students already have data available from other experiments, have them jump right into the diagram creation and critique portions of the activity.
Very scholarly article that looks at the role literature helps teach us about the diversity of our culture. The author looks at various aspects of literature and then gives teacher resources and a helpful bibliography.
In this interactive math game, students use absolute value to determine how many feet below sea level Carl must be to stay away from the shark.
Ratios
Type of Unit: Concept
Prior Knowledge
Students should be able to:
Calculate with whole numbers up to 100 using all four operations.
Understand fraction notation and percents and translate among fractions, decimal numbers, and percents.
Interpret and use a number line.
Use tables to solve problems.
Use tape diagrams to solve problems.
Sketch and interpret graphs.
Write and interpret equations.
Lesson Flow
The first part of the unit begins with an exploration activity that focuses on a ratio as a way to compare the amount of egg and the amount of flour in a mixture. The context motivates a specific understanding of the use of, and need for, ratios as a way of making comparisons between quantities. Following this lesson, the usefulness of ratios in comparing quantities is developed in more detail, including a contrast to using subtraction to find differences. Students learn to interpret and express ratios as fractions, as decimal numbers, in a:b form, in words, and as data; they also learn to identify equivalent ratios.
The focus of the middle part of the unit is on the tools used to represent ratio relationships and on simplifying and comparing ratios. Students learn to use tape diagrams first, then double number lines, and finally ratio tables and graphs. As these tools are introduced, students use them in problem-solving contexts to solve ratio problems, including an investigation of glide ratios. Students are asked to make connections and distinctions among these forms of representation throughout these lessons. Students also choose a ratio project in this part of the unit (Lesson 8).
The third and last part of the unit covers understanding percents, including those greater than 100%.
Students have ample opportunities to check, deepen, and apply their understanding of ratios, including percents, with the selection of problems in the Gallery.
Students focus on interpreting, creating, and using ratio tables to solve problems.Key ConceptsA ratio table shows pairs of corresponding values, with an equivalent ratio between each pair. Ratio tables have both an additive and a multiplicative structure:Goals and Learning ObjectivesComplete ratio tables.Use ratio tables to solve problems.

En este módulo final del plan de estudios de Grado 1, los estudiantes reúnen su aprendizaje del Módulo 1 al Módulo 5 para aprender los estándares de Grado 1 más desafiantes y celebrar su progreso. A medida que se abre el módulo, los estudiantes lidian con tipos de problemas de palabras comparativas. A continuación, extienden su comprensión y habilidad con decenas y números a 100. Los estudiantes también extienden su aprendizaje del módulo 4 a los números a 100 para sumar y restar. Al comienzo de la segunda mitad del módulo 6, los estudiantes se introducen en los monedas de montaña y cuartos, ya que ya han usado centavos y diez centavos en el contexto de su trabajo con los números a 40 en el módulo 4. Los estudiantes usan su conocimiento de decenas y otras para explorar las descomposiciones de los valores de las monedas. El módulo concluye con festividades divertidas de fluidez para celebrar un año de aprendizaje.

A newsletter for young people and their parents about managing money.
Take this online quiz to practice counting money. Find the total value of the number of dimes shown and select the correct answer. Questions are generated randomly so you can take the quiz over again.
Students build on their understanding of the structure of the place value system, start to use rounding as a way to estimate quantities, and develop fluency with the standard algorithm of addition and subtraction. Students focus on the precision of their calculations, and use them to solve real-world problems.
