Students reason about the meaning of adding fractions with unlike denominators in the context of an example problem. The mathematics task is intended to be a problem or question that encourages the use of mathematical practices. The dialogue is meant to show how students might engage in the mathematical practices as they work on the task.

In this lesson, students will describe which segments of society were included in the original Athenian democracy. They will compare and contrast early Greek democracy to democracy as it is exercised in the United States today. Students will participate in the democratic process through a role play activity.

This is an easy interactive resource that allows students to choose between 2 scenes, and then choose sound effects to accompany the short movie. With several options to choose from for each small clip, this proves a great lesson on how different sounds can change the meaning of a scene.

Students draw diagrams to develop conceptual understanding of multiplication. Precise, mathematical vocabluary is encouraged through discussion of students' representations of the story problems. This lesson includes a high-interest article as well.

Students will understand common Greek and Latin roots through participating in this engaging and interactive vocabulary game. Students will gain knowledge about word origins, and this knowledge and understanding will reinforce the connections among related words.

In this activity, students will find discounts and sale prices for items selling at 20% off and 40% off by using tables. They will then find the general rules, using a variable, for finding those discounts and prices.

In this activity, students will compare ratios with different denominators, and then with common denominators. They will also find unit rates.

This song created for the level 1 Realidades textbook demonstrates how to ask people what they are like and answer for yourself. Lyrics are available in English/Spanish; perfect for cloze activities.

In this lesson, students will use the first quadrant of the coordinate plane to graph points.

In this interactive, students will help Clifford sort letters by matching the first letter in each word to the correct box.

Students will make a list of new words by adding and switching vowels; i.e. cat to cot; net to nut; and bet to bat.

Students will have to listen carefully so they can match words that have the same middle vowel sound, like "stove" and "rose."

Students will look, listen, and learn! Students will look at a picture and find words that begin with the same sound as the picture. When they find a match it will create a word list.

Students will understand the subtleties and stylistic features of texts on unfamiliar topics. Additionally, students will learn that Gustavo Adolfo Becquer, was a Spanish poet and writer best known for his Rhymes and Legends. Also, students will analyze the poem and will learn that in Rhyme II, the poet talks about the anguish he feels concerning the uncertainty of the future and in the years that he has left to live.

In this activity, students will use the CelSheet App that multiplies the fraction by “1” to help determine the common denominator. Then they will use what they have learned to add and subtract fractions without the same denominators. As an extension, they will use the LCM command to quickly obtain the best denominator to complete the operations.

In this activity, students discover the relationship between a change in the dimensions of a rectangle and the change in the corresponding area.

In this lesson, students learn how to compare fractions. Students begin by drawing a picture to compare fractions then interact with a computer program.

Students make up a set of eight numbers that simultaneously satisfy given constraints. The mathematics task is intended to be a problem or question that encourages the use of mathematical practices. The dialogue is meant to show how students might engage in the mathematical practices as they work on the task.

Students find a rule that agrees with a giventable. The mathematics task is intended to be a problem or question that encourages the use of mathematical practices. The dialogue is meant to show how students might engage in the mathematical practices as they work on the task.

This lesson utilizes the concepts of cross-sections of three-dimensional models to demonstrate the derivation of two-dimensional shapes.
