How Much is a Million?
Students discover the magnitude of the number 100. The sense of the number is developed by allowing students to experience 100 by counting it, measuring it, feeling it, and doing it, hands-on
Illustrative Mathematics
How Many Cells Are in the Human Body?
Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some context to all...

10 Huh?
Students use powers of ten to make reasonable estimations for list of questions. They share their problem solving techniques with the class.
Curated OER
Lesson 3: Number Sense
Learners solve word problems using number sense. They convert fractions to decimals and mixed numbers. Pupils determine if a given fraction is greater or less than another fraction, and order numbers on a number line.
Curated OER
Prime and Composite Numbers
Prime and composite numbers are the focus of this mathematics lesson. In it, learners practice techniques for identifying these two types of numbers. They utilize the Inspiration program to complete a task that is clearly explained, and...
Curated OER
Fractions, Decimals and Percents
Students investigate the differences when using decimals, fractions, and percents. They focus on the process of using them in real problems and how to convert them from one form to another.
Louisiana Department of Education
Fractions, Decimals, and Percents
Fractions, decimals, and percents all say the same thing! Show your classes how to convert between the three forms using visual and numeric representations. Then lead them to an understanding of scientific notation.
Curated OER
How Many Stars are in the Sky?
In this star count learning exercise, students solve three problems using a given polynomial and its logarithm to determine the number of stars in a given area.
Curated OER
Whole Numbers
Student are assigned one of the sections on whole numbers. After reviewing the content, they teach their assigned sections to other class mates. They publish their findings on a PowerPoint slide show to use when they teach their section.
Curated OER
Riemann Sums
Students calculate the area under a curve. In this calculus lesson plan, students use Riemann Sums to find the area under a curve. They apply the boundaries of intervals as they solve for each area.
Curated OER
Riemann Rectangle Errors
High schoolers calculate the area under a curve. In this calculus lesson, students integrate the function to find the area under the curve. They use the Ti to create a visual of the graph.
Curated OER
Permeability (Magnetism)
Students investigate magnetic permeability and saturation. In this physics lesson plan, students explain how current carrying wire coils create magnetic forces. They interpret normal magnetization curves.
Curated OER
Too Many Tens
Students practice grouping in different ways by putting numbers up to 1,000 in the correct place value. In this place value lesson plan, students estimate items in a jar and then count them out by grouping them by 10s.
Curated OER
Using Inequalities to Problem Solve
Learners explore inequalities. In this Algebra I lesson, students solve and graph linear inequalities involving addition, subtraction, multiplication, or division. Learners use inequalities to solve and graph real-world problems.
Curated OER
Regressive Music
Student use the Ti calculator to graph sinusoidal graphs. In this calculus lesson, students use the CBL to collect and analyze data of sinusoidal graphs. They manipulate their collected data and make predictions.
Curated OER
Zeros and Blackbirds
Fifth graders convert kilometers to miles and calculate the range that historical aircraft can travel. They choose destinations by distance that can be traveled without refueling.
Curated OER
Calculus
Students make an inquiry with the aid of technology into the concept of functions. The emphasis of the lesson is on the interplay between the geometric and analytic information.
