Additional Notes

Chapter 1: This chapter is mostly reading for the students. Class time can be spent doing explorations as groups with some lecture. Problems from Chapter 1 may be best utilized if spread throughout the course.

Chapter 2: This chapter should emphasize sets as a means of classifying and de-emphasize extensive work with formal set notation. Venn diagrams should be introduced as an organizational strategy to assist in classification. If scheduling permits, you should start 2.3 during Week 3 to allow more time for Explorations 2.8 and 2.9.

Chapter 3: Preservice elementary teachers need to understand the connections between the arithmetic operations. They should study the properties of addition, subtraction, multiplication, and division, and understand why addition and multiplication share properties that subtraction and division do not.

In sections 3.1 and 3.2, students will learn and use algorithms for performing the arithmetic operations different from the standard algorithms used in the United States. Using and understanding unfamiliar algorithms will deepen their understanding of arithmetic.

One of the most important lessons learned from sections 3.1 and 3.2 is that it is not good enough for our preservice teachers to understand the "hows" of an algorithm, but they must understand the "whys."

Base 10 blocks would be very effective for sections 3.1 and 3.2. Exploration 2.8 (Alphabitia) should be done before chapter 3 is started. This exploration is referred to repeatedly throughout sections 3.1 and 3.2

Section 3.3 pulls together knowledge and skills from 3.1 and 3.2 to perform mental arithmetic and estimation.

Chapter 4: The explorations for this chapter should precede the textbook material. You will probably want to allow 3 1-hour classes for exploration 4.4. The instructors manual has very helpful information on this exploration. If there is time, you should do exploration 4.5.

The investigations in chapter 4 can be done either as homework or as group activities to turn in. You will probably want to emphasize the Sieve of Eratosthenes. Vera Prestion and Mary Hannigan have "hundreds" charts for the Sieve of Eratosthenes projects.

While there are interesting homework problems in the text, they may be best if done only if there is extra time after completing the explorations and investigations.

The units blocks or color tiles can be used to form rectangles from a given number of blocks/tiles. Use graph paper to record the various rectangles after they are built with the manipulatives. Cuisenaire rods are very useful for determining greatest common factor and least common multiple.

Chapter 5: Students need to develop strong understandings of the connections between the subsets of numbers in the real number system. They need to deepen and expand their understanding of the uses and meanings of the operations with these subsets.

Chapter 6: Emphasize proportional reasoning, rather than computational proportions. If students understand proportions, they will find themselves reasoning proportionally more often. Discuss and develop the idea that percents are ratios that are based on 100 rather than some other number.
