Graph Logarithms
Mathematicians graph logarithmic equations. Teach your students how to identify the intercepts of logarithmic equations and tell whether the function is increasing or decreasing. They find the domain and range of each function.
Curated OER
Multiplication
Third graders discover a connection between numbers of things in groups and groups. They solve number line puzzles for multiplications and identify data for 3 riddles in a multiplication context. They use number lines as sources for...

Application of Properties of Quadrilaterals in the Coordinate Plane
Students apply definitions and theorems to verify special quadrilaterals
using coordinate geometry. They apply the slope formula, the midpoint
formula, and the distance formula to justify that a given quadrilateral is a
parallelogram....
Curated OER
Quadrilaterals in the Coordinate Plane
Learners find the coordinates of the vertices of special quadrilaterals placed in the coordinate plane. They find the coordinates of missing vertices of squares and parallelograms.

Multiplying and Dividing Integers/Relay Race
Give your class a list of multiplication and division sentences that contain both positive and negative integers. Have them analyze them to see if they can discover the pattern with the signs. From these patterns, help them develop the...

Bean toss
Young scholars arrive at a verifiable rule, or set of rules, to handle all addition situations with signed numbers.
Curated OER
The Circumference and Diameter of a Circle
Ninth graders investigate the finding of the diameter of a circle in order to extend the practice towards finding the circumference. They differentiate between the distance measured across a circle from that of around the perimeter.
Curated OER
Fractions and Halves
Fourth graders examine halves of a whole and discover through activities that they must be exactly equal in size. Working with Geoboards and Dot-Paper Squares, the class practices finding halves that are both congruent and incongruent.

Line Of Best Fit: Feet & Forearms
Learners actively find the line of best fit. They gather their own data and then use a calculator to find the line of best fit, as well as the equation. They see how to use the TI 81 calculator in order to find the line of best fit.
Curated OER
Linear Progression
Students use graphing calculators to graph lines and create tables of values. They perform an experiment using M&M's and slinkys, then create their tables based on their results.
