Number and Number Relations: Lesson 2

Don't wait for a crisis to get your finances together. An economics lesson demonstrates the importance of understanding crucial documents, banking basics, and financial tools with the focus on Hurricane Katrina in 2005 and its effects.

There are four irrational numbers that participants need to graph. Pi(π), -(½ x π), and √17 are easy to approximate with common rational numbers. On the other hand, the commentary describing the irrational number 2√2 is not clear. It...

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...

Develop another way to find the equation of a line. The lesson introduces the procedure to find the equation of a line given two points on the line. Pupils determine the two points from the graph of the line.

Be sure to look both ways when making a two-way table. In the lesson plan, scholars learn to create two-way tables to display bivariate data. They calculate relative frequencies to answer questions of interest in the 14th part of the...

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Math wizards begin the lesson plan by comparing and ordering rational numbers. Using a number line, they discover the relationship between the numbers and practice ordering them in the correct way. They also review proper techniques for...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps - though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...

Students investigate place value in base ten. In this number sense lesson, students participate in an online lesson at www.shodor.org/interactivate/activities/NumberBaseClocks and demonstrate how to convert numbers from base ten to other...

Organization is the best way to make sure that ratios are set up correctly to be proportional. This video reviews how to solve ratio problems with addition and multiplication, shown in more detail in the prior two videos of this series,...
