Practice 8-3: The Tangent Ratio

This second of twelve algebra 2 units continues the first section's emphasis on matrices and using technology tools. Through these lessons, the class will manipulate polynomials and solve systems of equations, convert units, find...

What does geometry have to do with depression? It's an angle of course! Learners apply the tangent ratio to problem solving questions by finding missing lengths. Problems include angles of elevation and angles of depression. Pupils make...

Discover the relationship between tangent lines and the tangent function. Class members develop the idea of the tangent function using the unit circle. They create tables of values and explore the domain, range, and end behavior of the...

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....

From exponents to slope-intercept form, an array of extra practice exercises will reinforce necessary skills for your middle and high schoolers. The worksheets include practice with order of operations, graphing equations, scientific...

Making the transition from two-dimensional shapes to three-dimensional solids can be difficult for many geometry students. This comprehensive Common Core lesson starts with writing and graphing linear equations to define a bounded region...

Introduce your classes to a new world of mathematics. Pupils learn to call trigonometric ratios by their given names: sine, cosine, and tangent. They find ratios and use known ratios to discover missing sides of similar triangles. 

Is it possible that 8:4, 8/4, and 8 to 4 all mean the same thing? Young mathematicians explore the idea of a ratio. They then use their understanding of equivalence to solve for an unknown value in proportion. 

After viewing a nutritious presentation on salads as any part of a meal, viewers participate in a paper-folding activity to prepare them to calculate ratios of salad dressing ingredients. As an assessment, they actually make a...
