Completing the Square
Learners review how to use the completing-the-square method to identify maximum and minimum values of a quadratic function by watching a video. They see how the vertex form relates to the extreme values of a quadratic function, and use...

Equations Involving Factored Expressions
Be ready mathematicians of every level. This lesson leads to the discovery of the zero product property and provides challenges for early finishers along the way. At conclusion, pupils understand the process of using the zero product...
Curated OER
Properties of Operations as Strategies
Which property is shown? Scholars examine 10 multiplication equations to determine which property each displays. The properties aren't written for them, so this is a little more challenging. There are no numbers over 12 here.
Curated OER
Properties of Operations as Strategies
These multiplication problems give scholars a chance to display their knowledge of math properties. They use the zero property to solve one problem, write a related multiplication fact for a division problem, and complete a final...
Curated OER
Hands-On Equations: Teacher Notes
Math manipulatives are wonderful for demonstrating any number of mathematical concepts in a concrete and visual way. Learners review the addition property of equality and the zero property using a scale model kit (not shown). They...
