**Save the Zogs [[]]**
Use this interactive to practice identifying linear equations and their graphs. This interactive provides excellent visuals which allow the user to see the effects of coefficient and slope changes. There are nine levels altogether. To advance to the next level, the user must answer 3 questions correctly. The objectives for the nine levels are outlined below: Level 1: Identify equations that describe horizontal and vertical lines (four multiple choice answers) Level 2: Write equations that describe horizontal and vertical lines Level 3: Create a line based on its linear equation (horizontal and vertical lines) Level 4: Identify equations that have non-zero slopes (four multiple choice answers) Level 5: Write equations that describe lines with non-zero slopes Level 6: Create a line based on its linear equation (non-zero slopes) Level 7: Identify equations that have non-zero slopes and non-zero y-intercepts (four multiple choice answers) Level 8: Write equations that have non-zero slopes and non-zero y-intercepts Level 9: Create a line based on its linear equation (non-zero slopes and non-zero y-intercepts)

Notes:


 * Students CAN guess on the "identify equations" mutliple choice parts. Therefore, teachers would have to monitor students closely if using this as an assessment or grade. The incorrect answers remain highlighted, so if the teacher did this in small enough groups, he/she could easily check for accuracy by requiring the student(s) to show the teacher before pressing "next" during the mutliple choice parts of the activity (Level 1, Level 4, and Level 7).
 * If a student creates a graph that is incorrect, the computer gives a tip at the bottom of the screen.
 * If a student chooses an incorrect slope and/or y-intercept, the computer reminds the student to use the tracker to fine a best line.

**Modelling Word Problems [[]]**
This site shows students the value of modelling word problems, and encourages logical thinking by walking students through each step. Quote from the site ...."Algebra is easy when you can visualize the relationships presented in the problems." There are 8 problems altogether. The problems deal with multiplication and division. Great for use with an interactive white board (a lot of dragging).

This site also has two great videos to show the best use of the online modelling tool. The videos are at [[]]

Go here [[]] to see the pre-algebra examples and use the modelling tool for your own problems.

This site would be good to use in podcasts with Jing, etc.

Zona Land ... Definition of Function[[]]
Plan to create a cloze activity to go along with this site to promote reading strategies.
