The most effective vocabulary instruction teaches word meanings as concepts; it connects the words being taught with their context and with the students' prior knowledge. Six techniques have proven especially effective: Concept Definition Maps, Semantic Mapping, Semantic Feature Mapping, Possible Sentences, Comparing and Contrasting, and Teaching Word Parts. RI.9-10.4 word meanings/impact of choice

In this lesson students use proportions to find percents. Students examine guided notes, review guided practice, watch instructional videos and attempt practice problems.

The aim of this video is to introduce high school students to the engineering concept of road construction and to the reasons why problems might arise in road construction. Presentation of this concept is made more accessible to students by comparing road construction to the art of baking a layer cake. This simple comparison can serve to emphasize how important it is to follow proper procedures and to use proper materials for successful road construction. [21:46]

Activities and factsheets exploring ratios and proportions in everyday life. Interactive, colorful, and fun.

Students will analyze interactions between ideas, events, and individuals by creating a graphic organizer. They will utilize "I Never Had it Made" by Jackie Robinson for this activity.

A teacher created lesson plan to help students conquer how to make connections between directions in an effort to create something. This activity will have students sharing recipes and understanding why recipes should be followed in sequence.

In this video, Paul Andersen explains the final AP Biology practice on connecting knowledge. The video begins with an introduction to interdisciplinary studies and how science is changing over time. He describes differences of scale in size, complexity, and timespan. He also explains who different domains are important in biology. [7:25]

This site walks you through the benefits of visual organizers, and focuses on a variety of types: tables, charts, graphs, timelines, flowcharts, diagrams, and webs.

In CK-12 Middle School Math Concepts – Grade 8, the learning content is divided into concepts. Each concept is complete and whole providing focused learning on an indicated objective. Theme-based concepts provide students with experiences that integrate the content of each concept. Students are given opportunities to practice the skills of each concept through real-world situations, examples, guided practice and explore more practice. There are also video links provided to give students an audio/visual way of connecting with the content.

This sample chapter from Hurst's book Picturing Math is an excellent resource for using picture books and activities for learning computation.

Engineers use a series of steps called the design process to solve a problem. In this resource, featuring video segments excerpted from DESIGN SQUAD, watch teams of kids work through each of the five steps of the design process: 1) identify the problem; 2) brainstorm; 3) design; 4) build, test, evaluate, and redesign; and 5) share solutions.

An engaging and fast-paced game from FunBrain, where players activate their knowledge of place value and rounding. Numbers range in difficulty from easy to hard. However, for those who are up for a more serious challenge, there's also a super brain game that tests their understanding of decimals. Immediate feedback given.

In this 12-day Grade 2 module, students engage in activities designed to deepen their conceptual understanding of measurement and to relate addition and subtraction to length.  Their work in Module 2 is exclusively with metric units in order to support place value concepts.  Customary units will be introduced in Module 7.

Type of Unit: Concept

Prior Knowledge

Students should be able to:

Write and evaluate simple expressions that record calculations with numbers.
Use parentheses, brackets, or braces in numerical expressions and evaluate expressions with these symbols.
Interpret numerical expressions without evaluating them.

Lesson Flow

Students learn to write and evaluate numerical expressions involving the four basic arithmetic operations and whole-number exponents. In specific contexts, they create and interpret numerical expressions and evaluate them. Then students move on to algebraic expressions, in which letters stand for numbers. In specific contexts, students simplify algebraic expressions and evaluate them for given values of the variables. Students learn about and use the vocabulary of algebraic expressions. Then they identify equivalent expressions and apply properties of operations, such as the distributive property, to generate equivalent expressions. Finally, students use geometric models to explore greatest common factors and least common multiples.
