Teaching Percentages
Young scholars calculate percentages using the Percent Tricks method. They multiply and divide whole numbers. They count total number of candies in a bag and calculate the percent of each color.
Curated OER
Making Words
Third graders spell words and define homophone. In this making words lesson, 3rd graders decipher words from letter strips in an effort to identify the "secret word". Students use a set of letters to spell different words.
IMSA
Geometric Transformations with Matrices
In this math worksheet, learners find the values associated with the geometric transformations. They read the instruction sheet for completing matrices with translations, rotations, reflections, and scaling by adding and multiplying...
Curated OER
Mapping Districts
Students use maps to learn about the U.S. Census. In this 2010 Census lesson plan, students visualize census data on maps, use map keys to read population maps, and explore the concept of population density.
Curated OER
Understanding Fundamental Trigonometric Identities
Students are introduced to the basic trigonometric identities. Using a diagram, they discover why the parts of the unit circle as named as they are and use equations to finalize the Pythagorean trigonometric identities. They also review...
Curated OER
Classic Poetry
Fifth graders review the terms narrative and classic poetry. They are introduced to SMUGGLER'S SONG and compare the structure to recently read poetry. They join in on the refrain reading the story together as a class.
Curated OER
Fractals and the Chaos Game
Pupils explore the concept of fractals. In this fractals instructional activity, students play the "Chaos Game" via an applet. Pupils place dots on the screen to recognize that they have created Sierpinski's Triangle.
Curated OER
Comparison of Human and Chimpanzee Chromosomes
Students actively engage in the careful analysis of chromosome banding patterns and identify examples of inversion in homologous chromosomes.
Curated OER
Mapping Counties
Students practice reading a map. In this mapping lesson, students illustrate a map and compare and contrast the counties based on their population. Students also explore what a census is and read census data on a map. A student...
Curated OER
Lesson 2: Mapping Sub-districts
Learners learn more about the census. For this mapping sub-districts lesson plan, students visualize census data on a map, use a map key to read a population map, and better understand the concept of population density.
Curated OER
Seeing Double
Students develop an intuitive definition for symmetry after viewing a PBS video. They examine asymmetrical patterns and demonstrate their knowledge by changing them to symmytrical.
Curated OER
Getting Familiar with Fractals
Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.
Curated OER
