Curated OER
Fabulous Fractals
Students view a video to discover how patterns in nature relate to math. They explore the concept of exponential growth by observing and creating fractals. They solve and design word problems.
Curated OER
Design Patterns
Students extend and create patterns. Through a variety of activities, they discover patterns as they exist in math and their everyday lives. Students create a necklace that represents a pattern.
Improving Measurement and Geometry in Elementary Schools
The Sum of the Interior Angles of a Polygon
Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...
Curated OER
Fraction Strips
Get a handle on equivalent fractions through the use of manipulatives. Using area models, sets, and length manipulatives like fraction strips and Cuisenaire rods, the class will gain a deeper understanding of equivalent fractions....
Curated OER
Measure Up!
Discover ways to measure items without standard tools. In this measurements instructional activity, learners estimate how long certain objects are by measuring with a non-standard measuring tool. Young scholars check their estimates with...
Curated OER
Investigation- On The Surface
Students will examine solids to determine which has the least surface area. They will also understand the use of units, square units, and cubic units. There is also the teaching and application of geometry formulas to perform calculations.
Curated OER
Fractions and Paper Folding
In this fraction lesson, pupils manipulate paper by folding it to create different shapes and sizes, they explore the concept of fractions, and discuss their observations as a class. This is a great lesson for getting students interested...
Curated OER
Fatal Accident
Eleventh graders explore, examine and study the impact of personal decisions on the safety and health of self and others. They assess how to evaluate individual coping skills to manage life-changing events. Each student defines and...
Curated OER
The Trapping of Trapezoids
This is a nice hands-on activity where young geometers create trapezoids and calculate their area by looking at areas of quadrilaterals and triangles.
Curated OER
Study Guide for the Advanced Placement Calculus AB Examination
Is this going to be on the test? A calculus study guide provides an organized list of important topics and a few examples with answers. The topics include elementary functions, limits, differential calculus, and...
Curated OER
Using Integer Tiles
Demonstrate how to add and subtract positive and negative numbers using tiles. Pupils complete a variety of activities on a worksheet, including mixed addition and subtraction problems, subtracting and adding opposites, and magic squares...
Curated OER
Fraction Animals
Second, third, and fourth graders explore fraction strategies and division by splitting sets of farm animals into equal numbers. Independently, they read word problems, solve them, and check their answers.
Alabama Learning Exchange
Systems on a Mission
Solve systems of equation problems using four different methods: elimination by addition or subtraction, graphing, elimination by multiplication, and substitution. Middle schoolers are then given a series of "missions" to complete.
Curated OER
Equivalent Algebraic Expressions
This online worksheet can be printed, projected on the board, or used as example problems for the class to solve. They write equivalent expressions for a set of given equations, 14 total. This page contains an answer link and links to...
Curated OER
Add or Subtract Whole Numbers Up to 1000
Elementary schoolers solve practice problems on the board and are shown how to line up the numbers for addition. They solve various addition problems in small groups. Everyone continues the same process for solving subtraction problems.
Curated OER
Garden Scavenger Hunt
Second graders examine the metric system. In this metric system lesson, 2nd graders compare measurements of common objects in metric units. Students compete in a garden scavenger hunt.
Curated OER
Graphing and Analyzing
In this graphing and analyzing worksheet, 9th graders first state if each graph represents a linear or nonlinear relationship. Second, they create a difference table for each set of data presented and determine whether it represents a...
Curated OER
Precalculus Exam
In this precalc lesson, students write out definitions, identify functions, solve integrals and derivatives and graph trig functions as they relate to angles. This is a final exam for precalculus. There are 80 questions on this exam.
Curated OER
Water Conservation
Learners explore types of water reserves. In this water conservation lesson, students brainstorm ways water are used in their homes. Learners use a graduated cylinder to simulate the amount of water on Earth and the amount that humans use.
Curated OER
An Introduction to Quadrilaterals
Students explore the concept of quadrilaterals. In this quadrilateral lesson, students play with a floor tile applet to see that there are many types and characteristics of quadrilaterals including parallelograms, trapezoids, rectangles,...
Curated OER
Which Quadrilateral Is It?
Students prove conjectures about geometric figures on the plane or in space using coordinate geometry. They develop fluency in operations with real numbers, vectors and matrices using mental computation or paper-and-pencil calculations...
Curated OER
How many isosceles triangles can you find?
Seventh graders recognize the characteristics of isosceles triangles. In this isosceles triangle lesson, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.
Curated OER
Partial Quotients
Fifth graders examine the partial-quotients algorithm for finding the answer to a division problem. For this partial quotients lesson, 5th graders demonstrate the process of division through a series of estimations....
