Associative Property
Here is a new twist on teaching the associative property of multiplication. The author of this presentation makes an analogy between the associative property and a couple getting married. The numbers, like people, are separate, but when...

Properties of Equality
What assumptions are made in order to solve equations? An instructional slideshow provides an overview and guided examples of how properties of equality can be used to justify each step in solving equations.
Curated OER
Multiplication is Commutative
Your class knows about the commutative property of addition - now introduce them to the commutative property of multiplication. They review the concept, work through some examples, then try a few problems out on their own. One property...
Curated OER
Factor Pairs
This presentation covers a lot of ground. Square numbers, metal math computations, commutative property, ordering positive and negative integers, factoring, and real world problem solving are all covered. Use over the course of several...
Curated OER
Counting on to add
A cute little frog helps learners hop from number to number on the number line as they count on to add. They use the commutative property of addition to add the same numbers two different ways. A cute, simple, and potentially helpful...
Curated OER
Quadrilateral Investigation
A good classroom tool is always great to have around. This tool provides learners with an opportunity to view and investigate the properties of quadrilaterals. Each slide contains images of a square as it is dissected into various...
Curated OER
Temperature
Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Magnetism
The compass was first used in 206 B.C., but we didn't discover magnetic poles until 1263 A.D. Presentation begins with the history of magnetism before continuing on to magnetic fields, magnetic forces, electromagnets, currents,...
