ManipulativesAll manipulatives for the workshop will be supplied by the host schools and the publishers. The Lab GearThere is a fair amount of info about the Lab Gear at the link above, and links to a book of activities from 1990 (Algebra Lab: High School), a SmartBoard "Gallery", and the animations I used in the workshop.Our worksheets (see Handouts) are from the two Algebra Lab Gear books, both available from Didax: Basic Algebra, and Algebra 1. Both include a Common Core correlation. I recommend getting both books. While there is overlap between them on the main topics, they differ in what they cover, in their sequencing, and in their style. Having both will give you maximum flexibility. Either of them is a lot more userfriendly than the 1990 book, and moreover all their problems will work with the distribution of blocks offered by Didax. Note also that the free online book does not include the 3D blocks.The blocks are also available from Didax. Each "student pair" box contains 24 ones, 8 fives, 2 twentyfives, 18 x, four 5x, eight x^2, 4 xy, 8 y, two 5y, two y^2, one x^3, three x^2y, three xy^2, one y^3, and two corner pieces.A class set includes twelve student pair boxes and both books. Workshop participants will be able to purchase those, and the Lab Gear books, at a discounted price (20% off!) Other Manipulatives11 by 11 Geoboards and rubber bands — should be available from many sources. Many geoboard lessons are in my Geometry Labs book. (See below.) Other lessons (geometry, trig) in Geometry Labs involve a 10cm circle geoboard I designed. It is on the back of a standard 11 by 11 board, and it is called the CircleTrig Geoboard. It is available from Nasco, at a 15% discount for workshop participants. Online Manipulatives: For a free online 11 by 11 board, you should go to Didax. BooksAlgebra: Themes, Tools, ConceptsSome of the work we will do is drawn from Algebra: Themes, Tools, Concepts (ATTC), an algebra textbook I coauthored with Anita Wah in the early 90's. It was groundbreaking in some ways, includes many extraordinarily effective approaches to the teaching of algebra, and is very compatible with the Common Core State Standards. On the other hand, it is not particularly easy to use as a textbook, and never became a bestseller. It is available absolutely free on my Web site, along with its Teacher’s Edition and more.
Also: Stairs and Squares (includes Geoboard Diagonals, and Donna's Stairs) Related lessons in ATTC: The whole book, by lessons or chapters. ATTC is not easy to navigate. Here's a onepage index to selected topics and tools. Geometry LabsSome of the work we will do is based on my book Geometry Labs:
The book includes many more labs, plus answers and teacher notes. It is available for free download on my Web site. In the fourday version of this workshop, we also explore: Area on the Geoboard (Lab 8.4 and 8.6)) Geoboard Squares (leading to the Pythagorean theorem) (Labs 8.5, 9.2) Simplifying Radicals (Lab 9.3) Distance from the Origin (Lab 9.4) My Math Education PageSome of the work will be based on material that is available elsewhere on my Web site. On some of those topics, there are more curriculum files available on the site than you have in your binder. You'll also find teacher notes, some answers / solutions, and pedagogical / philosophical comments there. Good places to start:
(includes teacher notes for the activity, plus specific worksheets for TI calculators, or Desmos, or GeoGebra)
