# eMATH March 2023 Newsletter

Posted on

Spring has finally arrived, at least on the calendar. Of course, we hope you all had a great Pi Day on March 14th (check out these fun pi facts that may just blow your mind). We’re excited to be moving through the second half of the school year and can see the end approaching. We’ve got a few more new resources to post before the year is over, so let’s get right into our new additions.

### NEW MATERIALS FOR TEACHERS

Here are the new teacher tools to use in the classroom for each of our courses:

• Unit 9 (Area) – Form B Unit Assessment
• Unit 10 (Solids) – Practice with Surface Area. This is a great set of problems to give students practice on drawing surface area nets and calculating the surface area of prisms.
• Unit 9 (The Geometry of Angles and Triangles) – Form B Unit Assessment
• Unit 9 (The Geometry of Angles and Triangles) – Practice with Supplementary and Complementary Angle Pairs. In this worksheet, students get a chance to reinforce their understanding of supplementary and complementary angle pairs through both numerical work and some algebraic work.
• Unit 7 (Exponents and Roots) – Solving Equations Using Square Roots and Cube Roots (Enrichment). This worksheets gives your students who need more of a challenge a chance to solve multistep equations where they must take either a square root or cube root to solve.
• Unit 8 (The Pythagorean Theorem) – Form B Unit Assessment
• Unit 9 (Volume and Surface Area of Solids) – Form B Unit Assessment
• Unit 9 (Volume and Surface Area of Solids) – Basic Volume Practice. In this worksheet, students get practice calculating the volume of all of the solids they saw in Unit 9, including leaving some answers in terms of pi.
• Unit 9 (Roots and Irrational Numbers) – Form A Unit Assessment
• Unit 9 (Roots and Irrational Numbers) – Exit Tickets
• Unit 9 (Roots and Irrational Number) – Designing a Fenced in Area – Modeling Problem. In this extended modeling problem, students determine the dimensions of a fenced in area based on the amount of fencing and the area enclosed. Solutions are irrational and force the students to use the quadratic formula or completing the square.
• Unit 8 (Right Triangle Trigonometry) – Form D Mid-Unit Quiz
• Unit 8 (Right Triangle Trigonometry) – Multistep Right Triangle Trigonometry Practice. In this worksheet, students are given the chance to solve trigonometry problems that require more than one trigonometric ratio.
• Unit 10 (Polynomial and Rational Functions) – Practice Finding the Zeros of a Polynomial Algebraically. In this lesson, students find the zeros of quadratic, cubic, and quartic polynomials by factoring, including factoring by grouping.
• Unit 11 (The Circular Functions) – Form D Mid-Unit Quiz

### THE PEN(CIL) IS MIGHTIER THAN THE SCREEN

In case you missed our latest blog post, read HERE about why it’s so important for math to be written out. Hint: it’s not just because Good Will Hunting wouldn’t have won an Oscar if Matt Damon had done his calculations on a smartphone.

### Have You Heard of Any of These Mathematicians?

Well, you should have! They’re some of the most important mathematicians in the history of math, and not just because they’re women. Learn more about Hypatia, Ada Lovelace, Mary Cartwright, Katherine Johnson, and more HERE. Happy Women’s History Month, y’all!

Oh, and by the way, Regents Reviews are coming in June!
