2.4 Algebraic Reasoning

EQ: How can you show your algebraic reasoning in a 2-column proof format?

Review algebraic properties of equality (addition, subtraction, multiplication and division) along with substitution and the distributive property. Additional properties covered include reflexive, symmetric and transitive (for algebraic equations, segments and angles).

Prep work: p96(3-6, 13-14, 19-42, 46-47)

Retake assignment for Ch. 1 – only for those wanting to retake the Ch. 1 Assessment. You also need to complete a majority of the problems on any missing assignment.

18 players competed in 3 quads and a swiss six on September 22nd. October’s winners were: Jack Woo McClain (Q1), Owen Young-Flynn (Q2) and a 3-way tie in Quad #3 between Alan Compton, Jimmy Hicks & McRey Moyer. Kevin McCoy and Sheldon Van Enk tied with 2.5 wins each in the swiss six.

Complete results from the September’s Quads can be found at: NWSRS results

All quads are OSCF qualifiers and NWSRS rated. Quads are also USCF rated when all members of a quad are USCF members.

The next quads are coming up on October 20th from 1:30 to 4:30. Just $10 to enter with the winner of each quad getting $10 and free admission to the next Bethel Quad. Remember if a quad chooses a longer time control, it will likely run later than 4:30.

Send an email to mike.myers@bethel.k12.or.us to reserve a spot. Onsite registration between 12:30 – 1:15.
