Curated OER
Worksheet 19
In this math worksheet, learners try to fit a line to a set of data. Then they use the least squares method is based on minimizing the sum of the squares of the errors.
Curated OER
Estimating Fish Populations
Students describe the mark/recapture method used to estimate fish populations. They explain the importance of being able to predict population numbers.
Curated OER
Forms of Exponential Expressions
Your young physicists analyze the forms of four equivalent exponential expressions representing an amount of a radioactive material in a substance. They show how each expression is equivalent to the others and what aspects of the decay...
Curated OER
Connecting Formulas Related to Geometric Figures
Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.
Curated OER
Symmetric Secant
Mathematicians use a symmetric secant line to prove the derivative at a point. For this trigonometry lesson, students create secant lines on the navigator to analyze the derivative. They move the lines around and make observations.
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
Light Beam
Students measure and convert between units. For this geometry lesson, students investigate through measurements of distances. They relate the properties of circle to solving problems with radius, diameter and area.
