2. Warm-Ups: 2-step all
3. Create a dot to dot puzzle

OBJECTIVE: 1.3.3 Understand the location of points on a coordinate grid in any of the four quadrants. 1.5.6 Understand and apply a variety of strategies to solve two-step equations with one variable. ACTIVITIES/ASSESSMENT: Evaluationof process for solving 2-step equations. Students will enhance skills in 4 quadrant graphing by creating a dod to dot puzzle according to the posted guidelines. Students must complet 2 separate items - the picture and then a list of coordinates on a separate sheet. NOTES: Use the Shodor link to check. HOMEWORK: Finish Coordinate list on separate sheet

The guidelines for the dot-to-dot picture: Set up a piece of 1/4 inch square graph paper with an x and y axis in the center.

1. Must have points in all 4 quadrants
2. Minimum of 30 points
3. Points must be in order and numbered. You cannot pick up the pencil and move to another place.
4. Lines MUST change direction at a point (i.e., a staight line only has points at the end - no intermediary points)
5. Retracing a line is allowed, but remember the line must change directions at a point.

The picture must be something recognizeable. Some exclusions include:

• no logos
• no letters, initials, words
• no robots or space aliens
• no designs

Some acceptable designs might be vehicles, buildings, plants, animals, people and cartoon type characters.

2. Warm-Ups: Assessment - 2 step equations
3. Reconstruct Dot to dot
4. Intoduce plotting equations Start 5.1 on page 62

OBJECTIVE: 1.3.3 Understand the location of points on a coordinate grid in any of the four quadrants. 1.5.6 Understand and apply a variety of strategies to solve two-step equations with one variable. ACTIVITIES/ASSESSMENT: Students will reconstruct their dot-to-dot puzzles from a list of coordinates. PInvestigation 5 will involve pltting equations manually and on the computer - the primary emphasis will be to create tables form equations by substitution.
