### At-home math lesson: doubling and dividing

By Michael Avidon, math editor You can calculate the square root of a number to any number of places without a calculator. If the original number is not a perfect square, then its square root will be irrational. Therefore, the decimal expansion is non-terminating and non-repeating. This method will give you the best approximation to…

### Lesson 1: Proportional Relationships

By Michael Avidon, math editor Tables and Verbal Descriptions: For Students More in this series Lesson 2. Lesson 3. If you want to help your child, use our version for guardians. Performance Expectations (CCSS) This lesson covers the following parts of 7.RP.A.2: Recognize and represent proportional relationships between quantities. Decide whether two quantities are in…

### Lesson 1: Decimal Expansions of Rational Numbers

By Michael Avidon, math editor For Students: Performance Expectations (CCSS) This lesson addresses the following Common Core State Standard (CCSS) for Grade 8: 8.NS.A.1: Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert…

### Making a Solar Cooker (For Students)

### At-home math lesson: irrationality of the square root of 2

By Michael Avidon, math editor How do we know that √2 is irrational? This page provides an indirect proof (also known as a “proof by contradiction”). In general, to give an indirect proof of “Statement A,” you start with the assumption “Statement A is false.” Then you proceed logically until you obtain a contradiction —…

### At-home math lesson: Approximation of pi

By Michael Avidon, math editor You have been told that π = 3.14, but have not been shown where this number comes from. Here you will be shown a simple proof that 3 < π < 2√3 = 3.464. A similar, but more complicated, procedure could be used to get a better approximation. More in…

### How the flu pandemics compare

By Shawn Downes, English Language Arts editor Back in 1918, social distancing helped flatten the curve to allow life to return to normal. On Nov. 11, 1918, World War I officially ended. Many people were celebrating as one of the worst wars the world had ever seen came to a close. However, just as the…

### How to prepare for Grade 8 state assessment math exams

By Michael Avidon, math editor Knowing the format of the questions will help students succeed A good part of the work we do here is writing and editing items (questions) for high-stakes statewide exams.
