Chapter 1, Lesson 2 is a lesson in which you will learn how to compare the information in different columns in a table of values. We continue to look for patterns that might help us predict what is going to happen in the future, if the pattern continues.
Chapter 1, Lesson 3 is about how expressions can help us solve problems. For instance, if we were to join a hiking club with an annual fee and a charge for each hike, how much would it cost us to go on 15 hikes? Could we write an expression that would help us solve the answer for 2 hikes? For 3 hikes? Listen on!
In Chapter 1, Lesson 4 you will experiment a little with expressions after you view an example. You will need some kind of blocks (around 50 will be nice, so try Lego), a piece of paper and a pencil. It is important that you experiment for this lesson so make sure you have your materials ready.
Chapter 1, Lesson 5 is about Equivalent Equations. I can't tell you enough how important this concept is to the rest of our unit and the rest of your life as a mathematician. You will need to understand this concept in junior high, high school and throughout university math, should you decide to go that far! Just keep in mind that whatever you do to one side of an equation (such as 2 + 2 = 4, for instance), you have to do to the other side to keep it balanced. We're going to use the image of a balancing scale to help us with this lesson.
In Chapter 1, Lesson 6 you will be pulling together some of the concepts that we've covered over the last five lessons. You will need a pencil and a piece of paper (a calculator is probably not necessary but if you'd like to use one you may). We're going to look at a problem that is dear to your parents' hearts: one group starts at point A and another group starts at point B; at what time will they meet up? This is actually a very practical problem and you have all the knowledge and tools you need to find the answer.
