Challenging math problems worth solving.

The name “Open Middle” might sound like a strange name for a website about math problems. However, it references a very specific type of problem we try to encourage here. Most of the problems on this site have:
* a “closed beginning” meaning that they all start with the same initial problem.
* a “closed end” meaning that they all end with the same answer.
* an “open middle” meaning that there are multiple ways to approach and ultimately solve the problem.

Open middle problems generally require a higher Depth of Knowledge than most problems that assess procedural and conceptual understanding. They support the Common Core State Standards and provide students with opportunities for discussing their thinking.

Des problèmes mathématiques stimulants qui méritent d'être résolus.

Le nom "Open Middle" peut sembler étrange pour un site web sur les problèmes mathématiques. Cependant, il fait référence à un type très spécifique de problème que nous essayons d'encourager ici. La plupart des problèmes sur ce site ont :

un "début fermé", ce qui signifie qu'ils commencent tous par le même problème initial.
une "fin fermée", ce qui signifie qu'ils se terminent tous par la même réponse.
un "milieu ouvert", ce qui signifie qu'il existe plusieurs façons d'aborder et finalement de résoudre le problème.

Les problèmes du type "Open Middle" nécessitent généralement une profondeur de connaissance plus élevée que la plupart des problèmes qui évaluent la compréhension procédurale et conceptuelle. Ils soutiennent les normes communes de l'État et offrent aux étudiants des occasions de discuter de leur réflexion.

120 lessons start with introducing letters and letter sounds. Then students read and write words like “cat” and “fib.” Students learn more sophisticated phonics, affixes, and spellings, in a step-by-step way. By the end, they are reading and writing words like “communication” and “chrysanthemum.”

Free resources, including complete courses, made available by Open University — definitely MOOCish before MOOCs were cool.

Courses for students, parents, teachers and community members alike!

Developed for the second grade. Students will complete a number of small tasks to help them understand both conscious and unconscious brain processes. We will discuss the left and right hemispheres of the brain and which aspects of the body each hemisphere controls. Students will then have the opportunity to participate in a number of fun activities that will exemplify how the brain sends and receives messages through the use of goggles that the students will each wear while trying to walk and do other everyday activities.Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the teaching of biology at the elementary level. Unless otherwise noted, the lesson plans have been tried at least once by students from our partner schools. This wiki has been established to share ideas about teaching biology in elementary schools. The motivation behind the creation of this page is twofold: 1. to provide an outlet for the teaching ideas of a group of college educators participating in a workshop-style course; 2. to provide a space where anyone else interested in this topic can place their ideas.

In this lesson, students build classroom community by exploring environmental print and a teacher-created display that focuses on a favorite book. They then create and share their own presentations.

There is something for EVERY GRADE here!

This short video and interactive assessment activity is designed to teach fourth graders about which compound unit is longest? (english units).

This short video and interactive assessment activity is designed to teach fourth graders about which compound unit is shortest? (english units).

This short video and interactive assessment activity is designed to teach fourth graders about arranging numbers in specific orders.

This short video and interactive assessment activity is designed to teach second graders about comparing coins with pictures.

This site is designed to help students pass Chemistry and Organic Chemistry. Melissa used to struggle with this subject, so when she finally graduated with a bachelor's degree in Chemistry, she became a tutor so that you wouldn't have to struggle like she did.
With the right help, YOU CAN LEARN ANYTHING!
Topics include:
organic chemistry survival guide
thermochemistry
naming compounds and acids
dimensional analysis, significant figures, density guide
gas laws
stoichiometry
redox reactions
molarity
lewis structures
kinetics
titrations
matter, atomic structure, empirical and molecular formulas

This Crash Course Kids video reviews how substances can be organized into groups according to their various properties.

For students that have already been introduced to the water cycle this lesson is intended as a logical follow-up. Students will learn about human impacts on the water cycle that create a pathway for pollutants beginning with urban development and joining the natural water cycle as surface runoff. The extent of surface runoff in an area depends on the permeability of the materials in the ground. Permeability is the degree to which water or other liquids are able to flow through a material. Different substances such as soil, gravel, sand, and asphalt have varying levels of permeability. In this lesson, along with the associated activities, students will learn about permeability and compare the permeability of several different materials for the purpose of engineering landscape drainage systems.

The purpose of this lesson is to introduce the students to the Sun. They explore various aspects of the Sun including its composition, its interior workings, and its relationship to the Earth.

This lesson covers the topic of human bones and joints. Students learn about the skeleton, the number of and types of bones in the body, and how outer space affects astronauts' bones. Students also learn how to take care of their bones here on Earth to prevent osteoporosis or weakening of the bones.

Students are introduced to the fabulous planet on which they live. Even though we spend our entire lives on Earth, we still do not always understand how it fits into the rest of the solar system. Students learn about the Earth's position in the solar system and what makes it unique. They learn how engineers study human interactions with the Earth and design technologies and systems to monitor, use and care for our planet's resources wisely to preserve life on Earth.

Students write an owner's manual that helps them get to know their classroom, provides them with a sense of ownership, and lets others know about their classroom.
