algorithm. Discussed multiplication using duplication. Homework: Section 2.1 – 1, 11, 12a and 14. Assignments for
philosophy of mathematics were given. Reports are due September 10 (written and oral). Students are to find
“uses of number” from Numbers by Friday.

solving equations by the method of False Position. Discussed the dates from artifacts. Homework: Section 2.3 - 2(as
many as you need), 6, 7, 9, 12b, 16 (if you need it) 19 and 20.
September 3 – Collect the homework – students selected two parts that had no answers in the back. Discuss
decomposition of a frustum of a square pyramid to derive the formula for its volume. Discussed pi values for Egyptians,
Babylonians, and even the Hebrews from 3000 BC to about 650 BC. Looked at several formulas for volume that were
used in this time period. Homework: Section 2.3 – 21 and 22. Section 2.4 – 1a, 2a, 9a and b if you have time. Finish
reading Chapter 2 – reading lightly.
September 8 – Gave homework hints about # 19 from 2.3 and # 9a from 2.4. Discussed how Babylonians solved a
special quadratic equation, and three different systems of linear and quadratic equations. Homework: Verify that the
Babylonian quadratic formula used is equivalent to the one we use today. Section 2.5 – 4, 6, and 12. Moved the
deadline for reports to Monday September 13.
September 10 – Discussed last section of Chapter. Set Test date for 20th of September. Answered questions about
homework. Homework: Section 2.5 - #13 – work a couple of parts. Section 2.6 work 2 of the first four problems.
Google to see when & why the prime meridian is where it is. Verify the formula for the volume of a frustum of a square
pyramid.
September 13 – Discussed Ptolemy’s Table of Chords, Thales and the early Greeks. Students should have read through
section 3.1 – Test is Monday, September 20 on Chapters 1, 2, and section 3.1
September 15 – Reviewed what Thales knew. Began the discussion of the Pythagoreans, a video about the
Pythagoreans was played; saw a demonstration of a Pythagorean cup. Read about the Pythagoreans; be prepared to ask
any questions that you want to on Friday.
September 17 – Discussed when Thales and the Pythagoreans lived in reference to the Old Testament names students
know. Discussed prime, perfect, abundant, deficient, and amicable (friendly) numbers. Discussed how the
Pythagoreans might have constructed segments that have irrational numbers for the measure of their length.
Homework: TEST ON MONDAY 1-section 3.1. BY Wednesday, using a given segment whose length you call “one”,
construct the √2 ,√3, and √5. Discern which of the natural numbers 1-15 are perfect, abundant or deficient. READ
about Jacob and Esau’s reconciliation. How many critters were in the first herd that Jacob sent to Esau?
September 20 – TEST
September 22 - Tests and philosophy reports were returned. Discussion included friendly numbers, triangular
numbers, square numbers and several theorems about the figurate numbers. Homework: Section 3.2 – 3, 4, 6, 11a,
and find the first five Pythagorean triples generated by the forms used by Pythagoras, Plato, and Euclid.
September 24 – Discussed Athens a bit, the Platonic solids and Greek mathematicians. Homework: Section 3.2 - 8 and
another part of 11. Reports assigned today are due October 6.
September 27 – Discussed three famous problems of antiquity. Students should know what the problems were, who
created a solution, and what the solution was. Discussed the technique in Problem 8 on page 131 of constructing the 4th
proportion. Suggested students read #3, 4, 6, and 7 from Section 3.4 to see solutions proposed to the three famous
problems. Homework: Section 3.3 – 1, 4, 5b, read #17.
October 6 – Three students gave their reports. Discussed construction of a geometric mean, and where the arithmetic
mean is. Discussed contents of Euclid’s Elements. Homework: Section 4.2 – 7-11 and practice construction of the
geometric mean. Read about constructing the golden section/golden ratio (φ) and what its value is.
October 8 – Discussed number theory concepts included in Euclid’s Elements. Corrected what is a typing error. TEST ON
SECTIONS 3.2 THROUGH CHAPTER 4 IS SCHEDULED FOR OCTOBER 20. Homework: handout sheet on constructions,
Construct a regular pentagon using the method in the text. Finish the proofs that were assigned from last class. Section
4.3 -1, 6, 7, 11, 16 parts a and c at least.
October 11 – Quiz on construction with open notes. Discussed :another way to construct a regular pentagon;
Eratosthenes’ accomplishments and his sieve; and works of Archimedes. Since test is next week, the section of Chapter
5 (5.2) that has Diophantus will be included on the test. Homework: Pick up a sheet outside Dr. Floyd’s door to use to
