The purpose of this task to help students think about an expression for a function as built up out of simple operations on the variable, and understand the domain in terms of values for which each operation is invalid (e.g., dividing by zero or taking the square root of a negative number).

Domains are indicated at the end of a URL - you're likely to recognize many 3 letter domains like .com and .gov. Domains can help you understand the type of site you’re visiting. In our research, this is the main way educators currently teach students to look for reliable sources.

The Domains of Life: Life's Three Great Branches updates the five kingdoms classification scheme with the latest understanding of life's organization based on DNA, fossil, and biochemical evidence.

This web page describes two challenges that build fact and computational fluency as well as flexibility and reasoning. Each activity uses uses an ordinary set of double-6 dominoes, which students try to arrange into a magic rectangle and a magic square, according to given conditions. The page provides links to an interactive Dominoes Environment and a page of other domino activities (both cataloged separately).

This problem helps learners become more familiar with odd and even numbers and addition facts within five. By challenging them to justify their findings, it also develops reasoning and communication skills. The problem displays 9 dominoes and asks the student to sort them according to parity, and then into pairs totaling 5 pips. It poses questions that stimulate thinking about basic number concepts. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for extension and support, and a link to an interactive Dominoes Environment (cataloged separately).

This web page describes several games and puzzles that build number sense, fact and computational fluency, flexibility, and reasoning. Each activity uses an ordinary set of double-6 dominoes. After describing dominoes generally, the page provides rules for the basic domino game and a variation, and proposes several other challenges involving addition, multiplication and prime numbers. The page includes a link to an interactive Dominoes Environment (cataloged separately).

This interactive Flash applet provides a customizable set of dominoes that users can manipulate to play games or solve puzzles. It can be used with an interactive whiteboard to facilitate group work. Users can determine the size of a set (up to double-9), remove individual dominoes, rotate and move them, and change their size. The Teachers' Notes page includes a link to page containing domino games and challenges (cataloged separately).

Students will demonstrate the power of solar energy by completing a variety of activities, including the create of a Pizza Box Solar Oven.

This is a lesson plan template created to engage young readers and encourage students to read fluently. Produced for 1st grade students, in a face-to-face setting. It can be completed in two 30 minute chuncks in one day, or across two days. The purpose of this lesson is to build a greater love for reading in each student. Reading with expression can aid in reading fluency and comprehension. You will be using dance along videos and engaging songs to introduce fluency. Students will create individual projects and be provided with opportunities to work with a partner to assess their learning. Instructions to incude diverse learners are included in section 1, 4, 5 and 6.
