The Objective Browser makes it easy to find specific games and play them for yourself. You can access individual games by clicking on 'Curriculum' at the top of the screen and selecting 'All Learning Objectives'.
Objectives are sorted by grade. Click the blue expand arrow to the right of a grade to display all of the objectives in that grade.
Then click the objective you're interested in to see more information, including the purpose of the objective and the number of puzzles it contains.
Selecting the 'Games' tab at the top of this screen will list all of the games in the objective. Each game will have a summary as well as show the number of levels the game contains. Click on a level to open a new browser tab where you can play the game in Test Drive.
When you are done playing the level, you can continue browsing that objective or close the tab to return to the Browse and Test Games screen.
