Texas Gateway: Using Geometric Concepts and Properties to Solve Problems

Address any kind of math concept or problem with a series of problem-solving strategies. Over 12 days of different activities and increasing skills, learners practice different ways to solve problems, check their answers, and reflect...

Sal illustrates more involved equations in this last video in a series. It follows "Simple Equations" and "Equations 2". He continues using color-coded markings to help increase students' understanding of a more complicated equation:...

Sal dissects basic algebraic equations of the form Ax=B. He encourages viewers to fully understand the equations before learning how to manipulate them. Furthermore, he teaches students how to solve the equations systematically. The...

The instructor demonstrates how to use the distributive property to eliminate fractions in an equation. Remember to have learners plug their answers into the original equation to check their work.

Solve this real world word problem in just one written step. The original inequality is a division problem, so to solve it, use the multiplication property of inequality. Was the problem solved by multiplying a negative number? Yes! So...

A word problem that needs to be written as an inequality to solve. This expression seems pretty straightforward and only takes one step to solve. But wait, the division property was used with a negative number so the inequality sign has...

A word problem with one variable and two given numbers. This word problem seems doable from the start. Wait, it's an inequality. Don't worry about that piece, just get the expression written and do the math. Watch this video and see how...

Given problem situations involving rational numbers, the student will select and use appropriate methods to solve the problems.

Given real-life problems, the student will use the Pythagorean Theorem to solve the problems.

Given a problem, the student will use concrete and pictorial models to solve equations and use symbols to record their actions.
