Students will identify and explain factors that contributed to ethnic tensions and conflicts in Sri Lanka. They will watch a video clip related to the conflict in Sri Lanka and critically analyze texts to determine the characteristics of the author. Students will also use a Venn diagram to compare and contrast the war in Sri Lanka with another conflict previously studied.

Students determine how far a brother and sister travel before they catch up with one another. 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 solve division problems with fractions and whole numbers in this interactive resource.

An interactive nonfiction book Don't Be Scared of Bats that students can read independently or listen as it is read to them. Students can compare illustrations and information presented in the text.

This film was selected for the 2004 National Film Registry of "culturally, historically and aesthetically significant" motion pictures. It is a famous Civil Defense film for children in which Bert the Turtle shows what to do in case of atomic attack from the Soviet Union during the Cold War.

In this resource, students will understand the subtleties and stylistic features of texts on unfamiliar topics. Additionally, students will listen to and read an original fragment of a poem about El Cid's exile, written in archaic Spanish. Also, students will learn that this is the oldest preserved Spanish epic poem which is based on a medieval warrior who fought during the reign of Alfonso VI.

In this resource, students will understand the subtleties and stylistic features of texts on unfamiliar topics. Additionally, students will read and listen to this poem narrated by Octavio Paz. Also, students will learn that Paz was a Mexican poet, essayist, and political thinker. He was awarded the Nobel Prize for Literature in 1990.

In this lesson, students explore elapsed time given a starting time and the number of hours that passed.

In this lesson, students will generate and analyze an algebraic pattern. Students will describe two different patterns. The first pattern taken from Koch's Snowflakes and the second pattern taken from a population of wolves and rabbits.

In this activity, students develop an understanding of the relationship between a number and its square root. They will first recognize perfect squares and order them from least to greatest with other numbers. Then students will estimate the square root of a number using perfect squares. Requires TI technology.

Prezi video is a great resource for students to use to create original content. The planning and execution of content represents levels 3 and 4 of Webb's Depth of Knowledge (DOK).

Students are investigating integer exponents with integer bases. 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 activity, students will work with composite numbers to find their prime factorizations in exponent form. They will create factor trees and use division as a means to finding prime factors. An extension involving finding a common denominator for two fractions is given at the end of the activity.

In this lesson, students will understand the concept of a factor. Students will determine the factors that belong to a whole number.

This activity will allow students to measure the circumference, diameter, and radius of a circle in a hands-on way. By being able to manipulate a circle and stretch it out the idea of circumference will be more concrete. Students will use each other, desks, and chairs to create circles that can be measured.

In this lesson, students explore factors of whole numbers. Students work with a computer program in order to practice factorization.

Students are given three vertices of a parallelogram. They are asked to determine where the fourth vertex is located. 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 are given two vertices of a triangle and its area. They are asked to determine where the third vertex is located. 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.
