Math Mondays: Teaching Work, Motion and Mixture Problems in Algebra 2
As part of our rational functions unit in Algebra 2, we stumble on the troubling work, mixture and motion word problems. You know, if train a leaves at 1 and train b leaves at 3 and...or if one pipe fills a tub at a rate of 20 liters per minute and another pipe drains it at 12 liters per minute... my students groan when we get to these. Despite having worked with word problems and real world applications for years leading up to this topic, it is still a struggle for many students.
Math Mondays: Multiple options for Systems of Equations
Systems of equations is a great, open-ended math topic to work with. Over the years, I have developed multiple assessment projects for systems of equations. I like to give students choice of projects. Here's a brief introduction to 5 project to use in your own classroom:
Math Mondays: Raising the Roof with Trigonometry
Trigonometry is covered over three units in my Precalculus class. In the first unit we work on graphing trigonometry and trigonometric functions. The second trigonometry unit includes such topics of angles of depression and elevation, identities and the law of sines and cosines. The final trigonometry unit works with vectors.
